 Good morning students. It is Tuesday, April 14th. Most of you are going to be spending today making sure that you get your exam done. You have a two-hour time block from when you open up the exam. It needs to be done today if you did not get it done yesterday. And only a handful of students did it yesterday, but it went well for all of them. If you have any technical problems, remember that you need to contact me immediately. I will deal with those on a case-by-case basis, seeing how we can work through your difficulties. I'll be monitoring email and text messages throughout the day. There will be short periods of time where I'm away and I might have to get back to you within a half an hour or so. Please don't wait until late this evening to start the test. If you wait until late this evening, I'm not going to be able to help you if you run into difficulties. And today is the deadline for that test, unless you contact me ahead of time and you've got some sort of documentable reason why you need to take the exam later tomorrow or Thursday. That would be the absolute latest. And again, that's on a case-by-case basis only for students who contact me with a credible reason why they cannot take the exam today. So make sure, get in, do your exam, do your best on it. Know that every student's going to have a slightly different exam. You need to have your own work, but you may use your notes from the class. But don't consult outside resources. If you have any difficulties, let me know. I am here for you. And then we will continue with the Unit 4 content on Wednesday. Some of you are still running behind schedule on getting some of your pre-lectures, your in-classes, and your homeworks done. You need to get on top of that, because in the end of the semester, you've got to be graded on what you've actually completed. So let me know if there's any way I can help you. But today, focus on your exam. Have a good day.
