 Hello, and welcome to the SE4X final live event. My name is David Corell, I'm your course lead, and I'm very excited to have with me Dr. Eva Ponce, Executive Director of the MicroMasters program. Hi everyone, and welcome to the third live event for SE4X, thank you for having me. Oh, of course. So we have I think a fun hour plan where we wrap up the course, we wrap up the fresh connection, and we talk about what happens next. So with that, I'm gonna go to the presentation and start thinking about what happens next in SE4X. So our agenda is three fold, wrap up the course, talk about the last round of the fresh connection which you played, wrap up the whole MicroMasters, talk about the CFX, and then we should have some time for your questions. Please interact with us using Slido. So you have the link there, you also have it on the platform and in your course email last night, you go to slido.com and you use hashtag SC4X to join in with us. There you can answer the polls that we've pre-populated for you and you can also submit your questions. So it's a great way to make this an interactive experience. So let's wrap up SC4X, supply chain technology and systems. I'd like you to go to Slido now if you would please while I'm talking and think about which topic interested you most in SC4X. We have a number of them here for you to choose from, database management, machine learning, ERP systems, transportation management, supply chain visibility and new trends. And you might remember if you watched our first live event that we asked you this there too. And at that time machine learning was very popular. I'll be curious to see how that comes out after you've taken the course. Personally, for me, I think database management is really fun but we wanna know what you think. So please take a look. Excellent. Remember go to the Slido.com and queue the code SC4X. Great. So our course is really divided into two sort of blocks. Block one has the database management part where we talk about data modeling, normalization and machine learning. And block two talks more about the software systems, how we choose which vendor, how we implement new software systems and new trends and technologies. I think there's two ways to think about this. One way that you might think about it is before the mid-term and after. But another way is in the first block, we're learning how to collect and appropriately store our data. And in the second block, we're learning all the powerful things that we can do sort of once we have a system set up. Okay, so I don't see anyone connected to Slido. Let's see if the technology is working for you guys. Go to a Slido.com and include the code SC4X. Capital letters does not matter. So you just need to go and include SC4X as a code and see if this is working for you. And in the meantime, we can continue with the presentation. Sure. Yeah. Just wanted to see if anyone is weird. By the way, yeah, let's see. Yeah, it looks like we have some viewers. So if you are viewing. Please vote. There's no wrong answer. You can use your cell phone. You can use your laptop. You can use any mobile device to do that. Yeah. And the questions are easy. Very easy. Okay. So I wanted to start with thinking about data management and how we talked about in the course and give you sort of a high level overview as you prepare your reviews and think about wrapping up this entire experience. Data management, we started with unstructured data or spreadsheets, which many of you are probably familiar with. And from there, we said that oftentimes the data we have needs to be cleaned up. It's not fully correct or fully complete. Companies are coming into lots and lots of data and we talked about the different sources that are happening. But we also noted that a company often doesn't have time to make sure it is correct and complete at the point that it's collected. So one of our jobs is to clean that data up and to get it ready for analysis. The second part of that is normalization and entity relationship diagrams. And to me, that's one of the funnest parts of the course because we think about essentially all of these numbers, just numbers that we have. And we try to understand the story that they're telling and the actual business that they're describing. And it's our job to organize that data into tables that make sense and that are normalized. So it's kind of a tricky part of the course, but I think a thoughtful one and a fun one. The next thing we went into was your SQL queries. This is where we learned how to query that data to get answers to important questions. And it's just sort of a side note. Some of the blended students who come to Cambridge and work with us and Ava will talk about that opportunity. Some of them have said to me, learning SQL was one of the most powerful things that I did in the MicroMasters. So I really encourage you to review that. Some of our CTAs do it just to review that experience. And I just wanted to add here that in the previous courses, we extensively use spreadsheets like Excel. But at a certain point when we have big data, tons of data, then spreadsheets are not enough. So you need to go through a database and a structured way to storage this data. SQL or any other tool to query this data is very, very useful. So especially nowadays with big data, all of the opportunities that company has to analyze these big data. Yeah, absolutely. So maybe moving on to the machine learning side. So now we have our data stored. And just like Ava said, so many companies are coming into so much data. We need a powerful way to store it and to work with it. But now that we have it, what can we do with it? And that was really a fun transition in the course to start thinking about machine learning. And just to sort of a high level overview, I broke our machine learning content up into sort of three pieces here. So the first piece is just the algorithms. We talked about a number of algorithms. You probably remember your PCA, your K-means clustering, your K nearest neighbors, your random forest. And so part of studying this material is just knowing those algorithms. Essentially, how do they work at a basic level? We didn't code them, but we understood the intuition or their logic. And what are they good for? I would especially pay attention to what could you use PCA for? Pretends like that. The next part that I wanted to make sure you thought about was measures. Just because we can do one of these algorithms, we understand how to implement it, saying orange, it doesn't mean it's the right tool or it's even a good tool. And we need to measure how well the tool performs. So there I would encourage you to think about your ROC curves. We talked about sensitivity and specificity. It was a brief conversation, but understanding that vocabulary, I think will serve you well. And we talked about overfit and underfit. So just because a model can be calibrated, it doesn't mean it's done appropriately to the question. And I really encourage you to think about those concepts at a higher level, just to understand them. And I think you'll be ready for what happens next in the course and hopefully in your career. I always suggest you to, at the end of a study when you do an analysis, ask yourself, makes sense? Does this result make sense? Because this always helps to go again through the results and try to understand what this result means that at the end is the most important part. Absolutely. And just the last part there. Oh, sorry. Oh, no. The very last part is kind of the how and why. I see sometimes where learners get very excited about learning the new algorithm or very excited about the technical information captured in the measures. But we also want to make sure that you are thinking sort of clearly about the foundational steps. What is the difference between supervised and unsupervised algorithms? How does labels or training data play into that distinction? Think about if we're making a prediction, which algorithms help us with that and which algorithms do something else? Many people are interested in point predictions, but not every algorithm serves that purpose. And think about regression. We can think about our machine learning algorithms as advancements beyond regression, but in some cases regression is a great tool for the job that you're doing. So I encourage you to think about the algorithms, what they're good for. Like Ava said, does the analysis make sense once you've done it? And what are the big conceptual differences between the algorithms and supervised and unsupervised techniques? I would say that these techniques are the most common techniques that our student at the residential program for the master degree, for the custom project are using almost all of the custom projects they are doing in order to analyze the data. Yep. So then after we talked about that, sort of in the second part of the course, we talked about another reality of working in supply chain management, which is software and working with these major software systems. So this was a fun part of the course where we talked about ERP systems. We talked about what they are, what the core functions of an ERP system are. We talked about how data can be transmitted between ERP systems. And I put in here in all capital letters because it connects to your previous coursework, the bullwhip effect. One thing to think about when you're reviewing this material is that communication can help us to reduce the impact of the bullwhip effect in really interesting ways. And so when you think about ERPs, don't lose sight of your SC3X coursework where we talk even in more detail about the bullwhip effect and how it can impact supply chains. We then went into architecture and implementation. So here we talked about how are we going to implement these programs at our company, where we have infrastructures, the service platform, software as a service, Dr. Caplus did a great job walking us through how big companies think about selecting the vendors for their software. He has a lot of experience in that. We really learned some best practices for choosing this major investment or choosing the right vendor for this major investment. And I would say here, there are different approaches. And the important thing is to understand the pros and cons for each approach and also depend on the size of the company, the complexity of the company, the supply chain in order to choose one or another. So we just provide the framework with different options and just to make you think about the pros and cons for each of these options. That's exactly right. The vocabulary gets you part of the way and then understanding the advantages and disadvantages really helps you understand the concept going forward. Yeah. And we also talked about tracking, tracing and technology. So in the track and trace, we had that great case study where we learned about when are we tracking, when are we tracing? What are the different pieces of technology that we need to execute that? We talked about control towers in this course and for our team, it was kind of fun to see all the popular press that's coming out now about control towers as a way to view that information as it comes into the company. So keeping in mind all of that going forward, I think we'll have you ready for the exam and have you ready for what people are talking about currently in supply chain management. And we closed with the discussion of new technologies you saw in that week that we're not really going to test you about those discussions that we had about new technologies, but gosh, I thought it was exciting that you get to hear from our experts here at CTL about things like drones and autonomous vehicles. Almost every time a partner company comes here to the office, someone wants to know what we think about autonomous trucks or about drones and it's really neat that we were able to share those insights with you and I hope you got a lot out of those. Definitely. Okay, so let's see the results of the first pool. So machine learning, 60% of their attendants are interested in machine learning, database management and new trends and technologies. So that's great. Excellent. So let's activate the next pool. Great. So we want you to ask in one war we are going to plot as a workload cloud. What surprised you most in SC4X? Anything new, anything that you didn't know about that really excited you were surprised you would love to know what it is. Anything you didn't expect. Yeah, yeah, yeah. Please let us know. Let us know. We are very open to any feedback. Absolutely. Always working to make the course better. Don't be shy, don't be shy to share your feedback with us. So let's see. Yeah, they are starting with the pool. Great. So while you're filling out that poll please let us know what you thought. I'm just going to talk a little bit about preparing for the exams and then what happens next for you career wise specific to the SC4X content. So I know you're thinking about your exams. You have your SC4X final coming up. It opens on July 4th. We're in our prep week now. And many of you are ready for the CFX and Ava's gonna talk a lot about that. So thinking about preparing for exams I'd encourage you to revisit your graded assignments and practice problems. Those are really helpful for understanding what could be asked of you and giving you a chance to practice executing those tasks. Definitely review your key concepts document. That's a great overview of all the most important points organized in a very distinct way so that you can sort of look through and see what the main topics covered in the course were. I put here also understanding over execution. You know, I think with some of these topics it's easy to think I'm gonna be a master of SQL and be able to do very complex queries which is a great skill to have but it's not the skill that I think we'll be testing you on as part of this course. So in this course we really wanna know that you understand is able to describe the pros and cons, the concepts but I would discourage you from thinking that being too masterful of a particular technique will get you a higher score. When you're preparing for these exams you wanna make sure you have a broad understanding of all the concepts and can execute these techniques at the level asked of you in the graded assignments and practice problems and then in the future you can build to that expertise or mastery of certain techniques. And the last part sort of pack your toolbox. What I mean here is that one of the really exciting things for me about being a part of this team and being the course lead here is that I know that all of you who studied hard and took this course can now do things in your career that you couldn't have done when we started in April and that's the goal of every teacher. So being a part of that knowing that now you can take this database management, this machine learning, all of this knowledge about software out into your careers is really exciting. So also please think about all this material not just as how it relates to the test but what you're gonna do with it in your life and I think we'll be really excited to hear from you. If you do. Yeah, spend some minutes just to have your takeaways for this course and write these takeaways. And I found myself very useful to do this kind of thing especially the future when you need to go back to your notes. Just one last point here. Yeah. This is just from some content I'm working on for the next run. So this is one of our colleagues here, the picture on the right, Michael Kress over at ABINBEV. He's the director of Tier 2 Logistics and we were talking about enrichment for SC4X and I was telling him about our course and he said this that I wanted to share with you as you're making time to study this material. He said just to analyze 16 billion rows of data then I want to process it. I want to analyze it. It's a whole new skill set. I think what's exciting for all the people taking this course is that skill set is in need. So just like we started this discussion people are coming in to lots of data and that demands new skills that people might not have. So I'm really excited about your opportunity in this course to review those skills, to learn them if you didn't have them and to take them into the workplace. Excellent. Let's have a look to the thing that surprised you most in SC4X, expert interviews. Great. Yeah, this is an effort that we did last run and we continue this run. What we want to do with that is to bring reality to the course. It's just to be the experts from the industry and to show that these techniques are currently being used in the industry. So usefulness and usability. Okay. Great. That's great. That's exactly what we were hoping would happen. I think, you know, in one of the first videos for the course, Dr. Kaplos says this is where we see how all of the things you're learning in previous courses are applied in practice. So that usefulness and usability is, I think, something we were shooting for. Definitely. Definitely. Yeah, and it's one of our approaches always. Yeah. Excellent. So let's move now to the brief of the first connection. So, excellent. So, the first connection. I'm super proud of you guys of the SC4X cohort and the previous cohort because the first time was the first time that we used the first connection in an online course. The team was selected to go to the global competition. They were selected to the final competition and finally they won the competition and it was great to see how the online technology allowed them to learn how to play the game and then they were together for a couple of days in Lisbon playing as a team physically there and then they won the war. And this happened last fall in September, 2017. The second cohort of SC4X has been also selected to go to the, were selected to go to the global competition and was selected to go to the final competition. This is going to happen in Milan, in Italy this fall, this fall, 2018. So congratulations to Amin, Adelabbi, Adelatif, Koffer and Lance that they will be representing the SC4X team in Milan this fall. So congratulations to you guys. Let's see what you did in the fourth round of the first connection. We have a total of 183 participants. 60, 76% are verified learners, 24% audit and the average score was minus 3.5%. This always happened because you know, there are people that play, there are people that they don't spend too much time playing the game, but we have very good results and also we have some outliers on the tail in the negative number. So that's why, but even in this case, the average score is not that close to the starting point but a little bit better than the starting point and the median was minus 0.28%. This is a distribution of the score. So as you can see here, even if we have some part of the population below the minus 10% of ROI in the company, most of the of you guys were above the minus 3.95, the starting point and an important part of the population was over 0%, which is we consider that a good result. If we have a close look to the result, almost 70% improve. Take different actions and in the round four, improve the initial scores. 53% score more than minus 1% of ROI and 43% more than 1%. And this, as I mentioned, is a good result. As you know, in this game, decisions are interconnected and sometimes I take one decision in one area but the impact of this decision in one area can improve this silo of the company but the impact on the ROI, since these have also impacting other areas of the company is not the one that you were expecting. And this is all about the game. The game is all about the interactions, how the decisions in certain areas of the supply chain impact in another areas in the profitability of the company. So let's have a look now to the top scores for this round number four. And we have here the three top players. We have Escudero, we have Rashad and Rafa Huysca. These are the players that play the first connection for the very first time. I know that there are some people that play for the second time, you did the last round and this round again. These people score very, very high and has a very good but to be fair with those that just take for the first time, I just pick those that take the game for the first time and this was the maximum score. 8.9% is really a very good result for the first connection. All of you were above the 7%. I also went through the average score for the four rounds. And this is what, this is a game. And what we want you is just to play, take risks and make decisions and see the effect of this decision on the impact on the company. But we really encourage you to play, to see the effect and to try to understand what is happening behind. So it's just a tool to help you to learn more about all of the different trade-offs that we are reviewing in the C4X and in the whole MicroMaster program, trade-offs between cost and service level, trade-off between the quality of the products that we receive from the supplier and the cost of this material and all of these kind of trade-offs that we have in the supply chain. Just to follow up on that, one of our CTAs is a very successful executive in online e-commerce supply chains. And I was asking him about how the fresh connection sort of related to his world. And he echoed exactly what Davis said. It really was a chance to capture trade-offs between different areas in a powerful and realistic way. So big congratulations to those of you that managed that so well in the game. Yeah. The game also illustrates that there is not one unique strategy that you need to follow in order to have a high performance in this game. There are different strategies. When I went through the top players, we can observe that. We can observe that some players choose more to go through an efficiency and focus on efficiency and reduce costs in inbound logistics, outbound logistics, every single part through the supply chain. We have also players that focus more on service level. Service level from the customer point of view in order to ensure a high service level for this customer and have also a very high service level from the supplier through the supply chain. And there are students, there are learners that focus more on a balanced strategy, just try to not be crazy with the costs and try to reduce as much as they can, but keeping a certain service level the whole time. So as I mentioned, and these three different strategies that you can see, the first one, focus on efficiency, or I was above 6%, same thing with this strategy that focus on service level or balance. So we can get same performance following different strategy, which is important here is, I don't think it's important which strategy you are, the overall strategy you are going to follow. The thing that you need to keep in mind is that every single decision that you make in each part of the supply chain need to be aligned with your overall strategy. This is a key point when you are playing this game. So in one war, I want to ask you about what was your main takeaway after playing the first connection? So I'm going to give you some time and I'm going to open this pool too. Before opening, yes, wait, we are, yes, I'm going to open this pool for you. And then in the meantime, what I'm going to do is to share the main takeaways that we had in the, this is the third time we are running the first connection in SC4x. So the main takeaways we have is strategy should be aligned. This was, I just mentioned here, there are different strategies in my war, but you pick your strategy and try to align all of the decisions with this overall strategy. Second theme is the game is all about translating the strategy into actions across all functions. So when we play this game on campus and we have been doing that for the last six years, students need to be aligned also with their partners. There are teams for people and they need to work together and each player play one role in the supply chain. In SC4x, it's different because you play the four roles. So it's much more time consuming because you need to review all of the reports, KPIs for all of the four functions in the supply chain. However, it is my understanding that it's easier for you to be aligned with yourself because it's the same person they want that is reviewed before. So it's more time consuming. You also learn more deep every single function, but I think that you are getting very good results because you are able to be aligned with your own decisions. As I mentioned, each decision represents a trade-off mainly between cost and service level. It's also a good way to illustrate how the different elements of the supply chain has an impact on the performance of the company. In this case, in this game, we measure this using the ROI. In this sense, you can see the impact of your decisions in the ROI of the company. So we found that playing the game online provide excellent results. We are very proud of how you are doing that. I also appreciate your motivation and engagement with the course. Also appreciate that some of you actively participate in the discussion forum sharing your experience. And at the end of this game, it's all about just to provide you a tool that you can apply most of the concept that you have learned across the program and see the impact on the profitability of the company. This is all about this game. Yeah, let's see what was your main takeaway from playing the first connection. We do not have results so far. Okay, so maybe we can move forward. Yeah, so let's move now to the MITx MicroMaster program. Let's see the big picture where you are, which one is the next step. So you are part of a huge community of SCX learners. There are almost a quarter of a million of learners that have taken at least one SCX courses. 15,000 of those learners are verified learners. And so far we have 1,062 cert credentials, MicroMaster certificates award. And we really hope that after August, we can add more MicroMaster credentials to this poll. So most of you already have completed the four courses. This is your fifth and last course for most of you. So I really encourage you to have time to review the whole material of SC4x to take your final exam. And I also encourage you to go through the CFX. The CFX is a comprehensive final exam. This is the final step and I know this is a long journey. I know that some of you might have started with us 18 months ago, two years ago, one year ago. And there is a lot of material to review. But in any case, I think it's worthy to, since most of you are at this point, almost at the end of the journey, just encourage you to go one more step, complete the comprehensive final exam, and then the MicroMaster credential. And why? Why you should do that? So here is the value proposition we have. It's a way to have some promote in your professional career or apply for a job in supply chain management. We have a lot of testimonials from students that are using the MicroMaster credential in order to apply for a supply chain management job. There are companies also like GE, they are granting interviews for MicroMaster holders in Massachusetts. There are also, there is a Brazilian company that they post some job openings, specifically for MicroMaster holders. We hope that more and more companies are going to do that, are going to offer specific jobs for these MicroMaster holders. So really, if you are interested in continuing in a professional way, applying this concept is an opportunity and the credential by itself is an standalone certificate that you might use for this purpose. Also, it's a pathway for a master degree here at MIT and also in any other university that are recognizing the MicroMaster as a pathway for credits. Currently, there are more than 10 universities in all over the world, all across the world. There are universities in Australia that are recognized in the MicroMaster credential, Queensland, Cartian University and Deakin University. There are universities in the United States like Purdue University, universities in South America, University of San Francisco de Quito, Galileo and Guatemala. There are also universities in Europe. There are universities, Zaragoza in Spain is also an example of that are recognized in the MicroMaster as part of the blame program. So if your goal is to continue studying and get a master degree in supply chain management, the MicroMaster is an opportunity to apply to these master's degrees in different universities. And MIT definitely is also one of these universities that are offering this master degree that we call the Blended Program because we combine the first part 100% online with the second part that is 100% on campus. Just to sort of echo that, this is such a neat thing. The MicroMaster itself was really an innovation and an exciting one and then the blended program. So for you learners who have enjoyed the content, I think it's a great opportunity and just to echo Ava's encouragement for you to join, it's such a neat way to learn the basics. You can learn things like mixed integer linear programs at your own pace here with one of our courses and then come to campus and enrich that in a really engaging environment. So if you're thinking about it, I would highly encourage you to do it. We have great fun working with the blended students here here in Cambridge and there's opportunities all over the world. So please give it a thought. It's a really neat thing. Yeah, then you are going to be part of this SCX community. We have study groups, we have meetup groups in many different cities. In Singapore, in Chicago, in Hong Kong, in Lima, Peru, in Spain, in many different cities. So really encourage you to be part, be active and take advantage of this huge community of SCX learners with one thing that is in common, that is this passion for the supply chain. So I think this is something that definitely keeping touch with us and with the community. So the next step for you guys, the first, as we mentioned, is to take the final exam in SC4X and do a great job because you need to pass SC4X as a verified student in order to be eligible for the CFX. So the CFX, what is the comprehensive final exam is the final requirement to earn the micromaster credential in supply chain management. And we are doing that because we need to ensure the value of this credential. As I mentioned, it's a standalone certificate you can use to go to the industry and say, hey, I have this knowledge in supply chain management and companies are hiding you because they rely on this institution, on this credential, on this certificate. So it's very important to guarantee that the person that earned the certificate has this knowledge. So this is one of the main purpose. The CFX is a 100% assessment. So that's why we don't share the solution. That's why it's just a pure test in order to earn the credential. The next CFX is scheduled for August 24th, 27th. We will open the exam on Friday, August 24th at 1500. And we will close the exam on Monday, August 27th at 1500 UTC. It's going to be, as always, a time exam. Yes, it's going to be also a proctor exam. And I'm going to talk a little bit more about what is a proctor exam. But all of you guys have the verified learners the opportunity to take a proctor exam in SC4x. And we did because we really want you to be prepared for the CFX. So this was a way to have an actual and real experience taking a proctor exam that we know. It's sometimes painful, there is a lot of rules, but we need to go through these rules in order to complete the credential. So who can take the CFX? Only those students that has completed by the day that we are going to enroll and verify people for the CFX, those that has completed the five SCX courses as a verified learner, you need to pass and complete as a verified learner the five SCX courses in order to qualify for the CFX. And once you are part of the CFX eligible, you definitely need to, the only way to take the exam is as a verified student. There is no way to take this exam as an audit student. So you need to always be a verified student, pay for the $200 via an ID verified student. You need to meet these two requirements plus pass the exam in order to earn the MicroMaster credential. Okay, so my question for you is, are you planning to take the next CFX in August? So let's see if you are planning or not to do that. If yes, which I expect you to do that, then you need to go through the MicroMaster portal at micromaster.mit.edu slash scm. And enroll, if you haven't done yet, please go to the MicroMaster portal and enroll there. We are going to communicate with you through that and we also want you to be in this portal because now most of you are at the end of the journey, at the end of the program and the MicroMaster portal is intended to be the space to facilitate you, discussion forums to facilitate you as space to be in touch with the SCX learners community. We are going to post and we are indeed posting the job openings in the MicroMaster portal. We are posting news related with SCM. We are posting the recent news about the blended student, whatever is happening around the SCM community, we are posting there. So I really encourage you to be there, independently if you are going to take on the CFX, just to be in touch with the SCX community and especially if you are taking the CFX. So the plan for the enrollment, so the SCX team will manually enroll all eligible learners. So we will wait until we close SC4X. We will wait until we issue the certificates for SC4X. So for those learners that after issuing the certificates for SC4X meet the requirements, that means have passed the five SCX courses as a verified learner, we will manually enroll in the CFX for August 2018. Does this mean that you need to take the CFX? No, that's not mean at all. This means that you are eligible and then you have till August 9th to make your own decision. If you want to take the CFX in August, you need to verify it in this course. If you decide for any reason not to take the CFX in August, you don't need to do anything. The only thing you need to do is not to verify because it's not your choice to take the CFX in August and then both things, you can unenroll by yourself or by after the deadline, those people that are not verified, we will unenroll them. So we are doing that just to be sure that all of eligible people have the opportunity to take the CFX. It is your decision to take or not to take. It is your decision to verify it or not. So, yeah, the next step for those that want to apply for the blended program, definitely you need to complete and pass the CFX and the micromaster credential and then you will qualify to apply for the master degree, the blended master degree at MIT or as I mentioned at any other university that is offering this pathway for credit if this is your goal. If not, I think there are many other ways to be in touch with us. We always appreciate your feedback. Do not hesitate to contact David today, to myself, to Chris Cables and share with us your feedback, how you think that we can improve the program. Be in touch with us also through the micromaster portal. Our community manager Arthur Grau, he's doing a great job keeping this community of ACX learners after the courses, engage, sharing news, organizing meeting apps, whatever. There are many, many ways that Arthur, every single day, arrive here with an idea to engage you more guys. So, I really encourage you to go through the micromaster portal. You can still collaborate with us as a CTA community teaching assistant. If you're interested, don't hesitate to send a note to us or to apply through the form we have as an ambassador. Ambassador is solely for micromaster holders, but those that are micromaster credentials holders, we also have a program in order to invite you to be our ambassador and to share with others what you learn, your takeaways about the program and let others know about this program. And we also have boot camps. Now this August, we are offering a boot camp here at MIT. This is just one week in person to allow those students that want to have the MIT experience to come on campus and learn more about that. So there are many different ways to be engaged with us. So please be in touch. Now it's time for questions and answers. So... Maybe the first thing I'll look at and I will ask able to speak to is you've responded to the question about if you will be taking these upcoming CFX and our results look like 67% yes, 33% no. Those of you that are no, maybe... What do you tell them? Yes, for the no's is a... Definitely there are many reasons. Sometimes are personal reasons. Sometimes you have an important event in your life that you cannot miss. Last year we have five people that was the wedding this weekend was like, oh my goodness, I cannot do that. But there are many, many different reasons. In any case, I want to mention you that this time for the CFX, the whole team, we have prepared new material that in order to help you to review the content. So Dr. Kaplanis, myself, we have prepared wrap ups videos for the five courses just to try to help you to say, hey, here are the main key concepts have kind of a review of this main concept in order to help you to go through the whole contents that you need to review. We are also offering this time a practice test. We have include in this practice test actual exam questions that we use for the previous round of the CFX. You will have the opportunity to download the software, the Proctor software, to take this practice test as a kind of real test because you are going to be Proctor. You're not going to be Proctor because it's just a trial but you can reproduce exactly the same scenario as the actual Proctor. Download the software, scan the room, verify, de-verify your identity and then go through some of the exam problems that we prepared for the previous round. You can, and I really encourage you to do that to try to solve by yourself and then after that and after be struggling with some of them, why not? You will have some problems solving videos that the staff has prepared for you. And this is just an example of how we think is a way to solve this problem. We also provide some tips in order to help learners to complete the CFX and to go through the process. So this is the material we just recently prepared for you in order to make the process a little bit less painful, maybe, just to help you with the review of the contents and also the review of the rules and all of the things that involve to have a Proctor test. Yeah, I think, yeah. To add to that, I would just say, those of you that said no, it could be, maybe not all of you that you're worried that it's very hard. And I do think the exam challenges you as it should and people that pass should feel very proud. But I also want those of you who might be worried to know how hard our team works to make it fair, to make sure it's correct, and to make sure you have all of the information you need to succeed on the exam. So just like Ava said, we're preparing videos, we're testing questions, we're testing our questions against the material that was in the course. So I think if you have the time to do it, we're gonna do everything on our end to make sure it's a fair passable test for students who studied hard. And I think all of you that are this far in all of your courses probably have done just that. Yeah, so we have a question, a question from Jonathan. He said that, is the CFX an open or a closed book exam? Very good question. So it is a Proctor exam and you are not allowed to use any other document more than the key concept document that we are providing through the CFX exam. And you can only use this document as a PDF in the virtual, as a digital PDF document. You cannot print the key concept document and you cannot have any other document in your desk. So it's more kind of a closed book exam. However, you are allowed to use the whole comprehensive version of the key concept document. So key concept document is allowed but only through the platform, through the document that we provide, you can download the PDF or you can just open it directly through the platform but you cannot print it. In terms of software, you are only allowed to use Excel or LibreOffice. That's all. Definitely we are designing the exam taking this into consideration. So we are not going to ask for things that you need extra or additional software because we are not allowing you to use any other software. I really encourage you to go through the rules. The rules are very clear. The things that you can do and you can't do are very clear. So during a Proctor exam, that's why the Proctor exam is a two-hours exam, exam one, we stop, then we have the second two-hours exam. During these two hours, you cannot leave the room, you cannot use your cell phone, you cannot have a cell phone or a mobile device in the room. And you just need to be focused on your exam. You need to open edX, open the course, open the key concept document through the CFX course, open Excel or LibreOffice and go through the exam just two hours. That's all. I would say that any other thing that we didn't explicitly say that it's allowed, you need to assume that it's not allowed. Sometimes I receive emails like, can I have a soda in my room? No, all of the things that are not included in the material that is allowed to use are, by default, not allowed. So yeah, there are some rules. Need to be very strict. It's a massive course. It's a proctor-virtual test and it's a 100% test. So we need to be strict for that. And I think it's a way to add also value to the certificate, you know, is that we need to ensure a rigorous assessment. So that's why we are doing that. And after that, we will celebrate. So, great. Let me follow up with just a couple more points from Jonathan. So he asked a question here about supervised versus unsupervised. That's a great question and I think you're really zooming in on the kind of things we might want to be sure that you know and we might assess you on. So there, I really encourage you to think about labels. Remember in a supervised situation, we know how the outcome variables are labeled and in an unsupervised situation, we're looking for those new relationships. So review the key concept document, review the algorithms, but I'd encourage you to think about, do we know what the outcome targets are? In that case, we're supervising or are we trying to understand them? I think approaching the problem that way will help you understand what the algorithms are trying to do. Yep. Also wanted to follow up with the comments here on the YouTube. The best thing about the course is learning how to handle the software. So thank you so much for that comment. Any other questions? It doesn't look like it. Excellent. So best of luck for the final exam. This is your immediately next step. And then I really hope and encourage you all to take the CFX, best of luck for the whole program. Hopefully by the end of August, we are celebrating that you are a MicroMaster credential. So, yep. Thank you so much. Thank you for the time and thank you for tuning in today. Bye, thank you.
