 What is up guys karma medic here and welcome back to another dose today? I have an incredibly exciting video to make I'm finally gonna be doing the decision-making section I can't even count how many comments I've gotten asked me to do decision-making so the videos finally here if you guys haven't noticed The channel is growing at an alarming rate probably by the time I upload this video will have reached a thousand subscribers Which is crazy can't believe it's gone in this far And I just want to say thank you guys for watching the videos and continuing to support me also I'll be doing a Q&A video soon, so make sure you leave questions down in the comment section below Follow me on Instagram and let's get right into the video So guys as a lot of you know when I wrote the UK cab back in 2016 the decision-making section wasn't part of the UK cat exam We had it on our test, but it would they were just piloting it with us So we had the option to do the questions, but they didn't count towards anything So I just skipped right past it forgot about it and moved on with my life when you guys were requesting for me to Do decision-making videos there was a problem because I hadn't done decision-making before what I decided to do was collaborate with Medify so that I could use their UK cat resources to learn all the theory behind the decision-making section and then use their questions that I could Practice them and prepare myself for making this video now before we get into the video where I solve questions live on camera I wanted to give you guys a couple of general tips I've been doing questions using the question bank for a couple of days now And I've come across a couple of patterns and things that I think will be very useful My first tip is to be very aware of confusing phrases or very aware of phrases that have very specific meanings And you want to know exactly what it is that they mean for example when I was doing the questions I came across the word some means any number above zero It doesn't mean more than 50. It doesn't mean less than 50 It could be any number more than zero but not equal to zero something else that I found kind of confusing when they said less than 10 It's important to keep in mind that less than 10 could mean zero the second tip I would give is to definitely learn Venn diagrams and probabilities These are topics that tend to come up in quite a lot of questions and it's fairly simple maths But basically in invent diagrams if you're ever making an or statement Then you're adding the two probabilities and if you're ever making an and statement, then you're multiplying them That's pretty much all you need to know, but I'll go into more depth in the video Okay, third and most importantly what I found when doing decision-making questions is that you really needed to follow a Line of logic very clearly and the way that I did this was to use diagrams Very very simple diagrams similar to this just with letters arrows Maybe some crosses just to indicate exactly how the logic flows from one part of the question to the next practice reading the question And summarizing it into a small diagram Then when you read the different statements You can take them use your diagram to figure out where they fit or if they don't fit and answer the question really quickly My fourth tip is to not make any Assumptions if you can't conclude a statement directly from the question or from the paragraph that's given to you Then it's wrong and my fifth and final tip is to just follow simple logical trains of thought Trails of thought don't make the question process more difficult for yourself Don't complicate things just make it in a step a step B step C fashion so that you can follow everything simply now with the General tips out of the way. Let's jump straight into the questions and go to my computer So here we are on the medified dashboard This is where you can see all the tutorials for the different sections of the UK cat And you can also see down here how you're doing compared to other students on medify So this is the tutorial for the decision-making section that I've watched in full to prepare for this video And it teaches you the theory behind the decision-making section It goes through a couple of questions too and over here. There's hundreds and hundreds of questions for each section I've mainly focused on the decision-making you guys can see that I've been doing pretty well in the decision-making section These questions where I got a zero out of one I've actually gone in four out of five But if you get one of the five questions wrong it marks as a zero so as you can see here I got four out of five right. I'm actually pretty surprised with how quickly I've been able to do well in decision-making I found the questions kind of fun almost like a game. And so it's been it's been really interesting for me to solve them Let's do some practice questions and go down to the decision-making section And I'm gonna choose the general one that has all the questions included together. And yeah, let's get started So these kinds of questions where you're asked to select the strongest argument from the statements below You want to make sure you make as little assumptions as possible You want to pick answers that are based on statistics or based on facts and that directly relate to the question directly try and solve A problem that's in the question something like that You don't want to do anything that's opinion-based or something. That's just not relevant So let's read the question should people who are addicted to illegal drugs be treated for their addiction to the NHS rather than Imprisoned if called by by the police. Yes, people who are addicted to illegal drugs recover much more quickly with the help of NHS Okay, not bad. Yes success or recovering from addiction has proven to be 55% when treated by the NHS But only 21% when released from prison That's a great answer because it's saying that it's a good idea to be treated by the NHS and it gives statistics to back up that claim There's no point these drugs being illegal if the police will not imprison them. It's an opinion These people may also be selling drugs to others. This is based on no facts It's just an opinion I think the first one is pretty good, but the second one is even better next question Should the NHS stop the funding of PrEP which can Protect the partners of people with HIV from infection in order to save money which can be spent on treating patients with cancer Yes, because a report found that there are other cheaper ways of preventing the transmission of HIV But no other cost-effective ways to treat cancer patient That's a very good answer because it shows a that there's a report so there's been some research and It answers the question directly that we can use other more cheaper methods to protect from HIV Whereas we can't do that for cancer. So we want to save where we can and keep using the money where we can't Yes, because PrEP prevents infection rather than treating it Okay, I mean that's a good answer, but not as good as this. No, because it's discriminating opinion No, because there's strong evidence to suggest that this can drastically reduce transmission This is a good, but it only answers the first part of the question. It doesn't have anything to do with patients Who need to be treated for cancer? Okay, so these types of questions where you're asked to choose if a conclusion can follow from the passage You definitely want to read the passage first So you understand what the context is that's going on and me personally I like to draw diagrams so I can just quickly follow the logic that's in the question Sometimes there's a ton and ton of information and I find that simplifying it into a diagram is really helpful So let me show you guys and you'll see what I mean conformists aren't always weak, but they are always ignorant so see to I Sometimes weak not all those that are ignorant are weak, but they will be arrogant. So some ignorant weak or Ignorant arrogant. So this is what I've drawn on my piece of paper. Okay, it's very simple very meaningless to anyone else it makes perfect sense to me and It helps simplify all the different things that I read in the passage into a diagram form It makes it easier for me to follow Maybe try this out if it helps you then great if it doesn't don't worry You don't need to use it so this first statement This is all those that are ignorant are conformists the passage at the very beginning says the opposite thing and if the passage says Conformists are always ignorant. It doesn't follow that ignorant people are always conformists So keep that in mind this the the sentence doesn't go both ways So this is a no a weak conformist will be ignorant conformists aren't always weak, but they are always ignorant So whether they're weak or not, they're still going to be ignorant. So this is true a weak person cannot be arrogant all those that are ignorant are weak Not all those are ignorant are weak, but they will be arrogant So if you're ignorant you are arrogant and here it says a weak person cannot be arrogant. That's not true We know it's the opposite Some arrogant people will be conformists conformists are always ignorant. Okay Not all those that are ignorant are weak, but they will be ignorant arrogant, so if you're ignorant you're arrogant and Conformists are always ignorant. So some arrogant people will be conformist. I think it's true More ignorant people are weak than arrogant. Well, this is confusing No, those that are ignorant are weak, but they will be arrogant. So more people are arrogant So this is a no this last sentence is that more people are arrogant than they are weak If they're already ignorant, I know that's a lot of words that sound very similar. So hopefully it makes sense So now we have a Venn diagram question I strongly suggest that you read the question first so that you know exactly what relevant information to go look for in the Passage and then you pick out the relevant information based on the diagram, which statement is true survey I don't care multiple types. So these are all the different Venn diagrams and their corresponding things So let's go through the statements one by one and decide if they're true or false six people like just nature So which one's nature triangle six people like just nature that is very true and We can stop right there because there's six here that fall into this triangle that don't fall into the circle rectangle or this trapezoid here So six people like just nature that is true And we'll stop there or we'll do the rest two people like game shows and period piece dramas So game show is this period piece drama is the rectangle So people who like both period these drama and game shows is four so that's false eight people like game shows game shows a circle If you add all these numbers up that's when eight nine people like soap operas if you add these up somewhere tonight So it's just that first one next question Amy's buying an external hard drive. She has the choice of either magnetic or solid state So magnetic solid state the probability that a hard drive will be damaged is 0.6 for magnetic 0.3 for a solid state Probably the harder will fill up before six months is 60 percent for magnetic and three fifths for solid state Three fifths is also the same as 60 percent. Hopefully you guys know that so considering only the likelihood of the hard drive being damaged Or filled up before six months should Amy buy the solid state hard drive So it damaged or filled up before six months. Let's see which one happens first. So That means you have to add the two probabilities. So the probability for the magnetic one is 0.6 plus 0.6 Which is equal to 1.2 and the probability for the solid state is 0.3 plus 0.6, which is 0.9 So should she buy the solid state hard drive? I would say yes The solid state hard drive is less likely to be damaged. That is true Yes, this also hard drive is more likely to fill up slower than a magnetic hard drive No, they're likely to fill up at the same rate. So the answer is a the first one Okay, we have another one of these yes. No questions. So let's read the passage first Only either Ian or Carl was successful for a job Okay, after they both had an interview on Thursday all the applicants except for Carl had over a 10-year experience applicants greater than 10 years except Carl some applicants with experience have excellent communication skills some applicants with experience communication No applicants from Manchester received an interview. Okay. I think my diagrams aren't going to be very useful for this one So I'm just going to look at the passage. Ian has over 10 years experience All applicants except for Carl had over 10 years experience So that means that Ian had over 10 years experience if Carl was successful at interview He Ian must have been from Manchester only one of them was successful. No applicants from Manchester received an interview So if Carl was successful at interview Ian must be from Manchester Could he have been from somewhere else and not received an interview? After they both had an interview so he can't be okay So since we know Ian and Carl both had an interview and no applicants from Manchester received an interview Then Ian cannot be from Manchester. Otherwise, he would have not had an interview, but we know that he did Carl does not have experience. So he does not have excellent communication skills Some applicants with experience have excellent communication skills. So some of them do some of them don't so we can't say Oh, Carl does not have experience. He does not have excellent some applicants with experience have excellent But it doesn't say anything about applicants without experience Some applicants without experience could also have excellent communication skills. So we can't say that this is true Yeah, it's not true. Ian is not from Manchester Let's see. What do we know about Ian? One of them was successful All applicants except for Carl had over 10 years experience. So Ian has 10 years experience I don't know if we can make this statement. I'm gonna go with no because we don't know if he was success. Oh Yes, of course, we know so They both had an interview and no applicants from Manchester received an interview So Ian is not from Manchester because we know that he had an interview. That was similar to this question here Applicants interviewed on Wednesday. We're not successful. We don't know anything about that We just know that they these two people had an interview on Thursday Okay, so it turns out that I got this question partially correct Let's see which question I got wrong. So this one applicants interviewed on Wednesday. We're not successful This can be concluded as the stem states that only either Ian or Carl were successful and they were both interviewed on Thursday So everyone interviewed on Wednesday must have not been successful Okay, fine given given the the assumption that there is only one job Taken up for a successful job Okay, and they both had an interview on Thursday and only one was successful Which means that anyone who interviewed on other days was not successful. So that's my bad in the reasoning Hopefully, that's okay. Anyway, let's move on to more decision-making questions So should a Prime Minister require political experience before leading the country again with these questions Don't make any assumptions try and look for answers that involve statistics involve reports involve research involve facts Should a Prime Minister require political experience? Yes Most jobs require experience before being accepted the role of Prime Minister is no different This is an opinion having a background in politics is most likely to provide a potential Prime Minister with the relevant skills required The role okay an opinion but seems pretty good No in the past Prime Ministers with political experience have been no more effective statistically than Prime Ministers without political experience No, the most important thing is that they understand the needs of countries whole okay So three is definitely the correct answer and here's why So you really need to keep your personal opinion out of these questions for example For me if I was going on personal opinion I would have easily just quickly chose this answer and been and moved on in this question The third answer shows that in the past from experience from evidence from research that it hasn't been as effective And that's the one we're going to choose more of these questions Either Zoe or Rachel raised the money raised the most money at the student bake sale for the charity committee All of the students except Rachel are graduates some of the graduates are also on the netball team No students studying chemistry raised the most money at the bake sale Zoe is a graduate So she's on the netball team some of the graduates are also on the netball team So it you don't have to be on the netball team if you're a graduate if Rachel raised the most money at the bake sale Zoe is studying chemistry either Zoe or Rachel raised the most money at the bake sale No students studying chemistry raised the most so if Rachel raised the most money then Zoe is studying chemistry true Rachel is not a graduate. So she is not on the netball team We know that some of the graduates are on the netball team, but it doesn't mean that a non-graduate Could not also be on the netball team So that's a no Zoe raised them the most money at the bake sale. She's not studying chemistry That's true because no students something studying chemistry raised the most money at the bake sale If a graduate raised the most money at the bake sale Zoe does not study chemistry Graduate all the students except Rachel are graduates So if it was a graduate then it could have been Zoe If Zoe if a graduate raised the most money in the bake sale Zoe does not study chemistry Yes, this is true All right, let's see. I've gone four out of five correct on this question Let's see which one I got wrong If Rachel raised the most money at the bake sale Zoe is studying chemistry If Rachel raised the most money at the bake sale we could conclude that she is not studying chemistry Yeah, but Zoe may or may not be studying chemistry and the text does not specify. Oh My mistake. Yeah, so if we if we know that Rachel is not studying chemistry, but we don't know about Zoe My bad homework should be banned in order to give students more time for extracurricular activities Personal opinion, of course, I'm gonna say yes No student wants homework, but try and push that aside when you read through the question and look for anything that involves statistics or past Research. Yes, most children find that they spend most of their free time completing the homework that they have been sent Okay opinion. It's just statistically homework has been shown not to improve academic performance It would be better for children to spend their time on activities that develop extracurricular skills instead It sounds pretty good. No, most parents think that if their children manage parents thinking it's an opinion It's no children in countries where homework is not generally given have similar levels of academic performance to those in countries where homework is encouraged Okay, that's also pretty good Homework has been shown not to improve academic performance. It would be better for children spend their time on activities So this part here is an opinion and it addresses extracurricular activities The read this one sounds good too But the reason I'm not gonna choose it is because it doesn't do anything to address the second part of the question Which is extracurricular activities? So I'm gonna go with the second option next question So an audit was performed detailing the number of surgeries performed by each individual surgeon in the past few months It was found that a total of this many surgeries were performed by four members Surgeon X surgeon Y Whatever which the following must be true surgeon Y performed the most Y performed a third of all and There was total was three three nine so three three nine times zero point three three three three So surgeon Y did a hundred and twelve. Let's call it hundred and thirteen and didn't do more thirty five a third of all 27 and the remaining so Let's see a hundred and thirteen plus thirty five plus twenty seven and 175 let's call that three Three nine minus one seventy five So we know that surgeon Z performed a hundred and sixty four So the first option can't be true at least a hundred surgeries were performed each month This was over the last three months We don't know if all of these were performed in one month or in half a month or over three months So I don't think we can answer that Surgeon Z performed the most we already know this is true from before so that's what I'm gonna go with Okay, next question So all adults that watch horror movies also enjoy thriller All the adults in the cinema are over 20 a Few of the adults in the cinema do not enjoy watching comedy and none of the adults that enjoy sci-fi have children So there are only adults in the cinema. I don't think we can say that it doesn't tell us whether there are children Are not also in the cinema Horror movies are more popular among adults than comedy movies all adults that watch horror movies enjoy thriller Okay, the adults in the cinema are over 20 a few of the adults do not enjoy watching comedy So I would say it's the opposite. I would say comedy is more popular The adults in the cinema may have children all adults that watch horror movies all the all the adults in the cinema over 20 Yeah, they could they could have children None of the adults that enjoy sci-fi have children but adults that enjoy other kinds of genres could have children Tony is an adult in The cinema he cannot be watching comedy a few of the adults in the cinema do not enjoy watching comedy But there are still adults that do enjoy it. So this is not true thriller TV series are popular amongst adults that watch horror movies All adults that watch horror movies also enjoy thriller. So that's true Great, I'm gonna read the questions and then go to the graph and the passage and pick out the meaningful and relevant information So secretion of growth hormone stops in the afternoon between 12 and 2 growth hormone between 12 and 2 in the afternoon p.m. It Stops, okay. It definitely decreases, but I don't know if it stops It just might be at a lower level. So I'm gonna say no Yeah, I'm not gonna say it stops because even at 2 there is still a basal level So I'm gonna say no strenuous exercise can lead to acromegaly in adults acromegaly Here high levels of constant secretion of growth hormone causes acromegaly. Okay does strenuous exercise lead to High concentrations. So here we see that strenuous exercise decreases the concentration So I'm gonna go with no blood concentrations of growth hormone. We're lowest at 10 a.m 10 a.m. Is somewhere here and that seems to be the lowest. I'm gonna go. Yes The average adult exercises I mean, I don't know anything about the average adult Hypoglycemia during street caused secretion during the midnight Okay Hypoglycemia so not eating or having low blood sugar levels during sleep caused secretion at midnight During midnight we stopped secretion. In fact, we were increasing previously to midnight at midnight We stopped so I'm gonna go with no, okay So again, I've managed to get one out of the five questions wrong in these types of questions average adult exercises I said no the correct answer was yes If you get any question wrong or if you're really really struggling on a question Just answer it guess it skip and move on because there'll be plenty of questions that are easier to answer Simpler and all questions are worth the same mark. All right guys So I've done quite a few questions as you can see down here I've done 30 questions today the sort of keeps track of how many questions you're doing over time So you know if you've been consistent in your studying. That's it for me That's enough decision-making questions in one day I learned everything about the decision-making questions from medify I watched their tutorial the video that they have to sort of explain the theory behind the section And then I did some practice questions over the last couple of days before recording this video And yeah, hopefully you guys can see that I've been able to do well and my progression over time I hope you guys were able to follow my logic I hope it all made sense and I hope that you found this video useful and interesting Thanks so much for watching make sure you leave a like on this video subscribe to the channel If you want to see more videos from me have a lot of exciting things coming in the future I'll see you guys in the next one. Peace
