Hi there. I just want to give a little bit of a video about the final exam. I just want to thank you for taking the time and sticking with this course as long as you have. We have several thousand people still actively on the way to a certificate and finishing up the last week, and then doing the final exam. the final exam will be a little bit different than the quizzes. The quizzes, you've been able to retake them over and over keeping the highest score until the deadline. and that's really because my goal for the quizzes is for you to learn and I feel like if you take the quiz more than once, especially the questions change a little bit you're learning, and so that's the idea. the final exam, I'm going to change it. You have a two-week period, and during that two-week period, you pick the time that you want to start the exam. And then a 24-hour timer starts, and you have to finish within 24 hours and submit it. You can log in. You can look at the exam. You can start answering the questions. You can save the questions, and then you just have to save and submit your final answers. The other thing that happens is the questions don't change. So you see one set of questions when you first look at it, and you could print it out, or do whatever. And so the questions aren't going to change, unlike the quiz, where the questions changed every time you took a look. I also am trying to, and I, as best I can to make the questions on the final more factual. I, I don't mind having a questions on the mid-term, on the, on the, on the quizzes that is kind of thought question where it makes you think or curious or bounce around or ask somebody because that, that, that triggers learning in ways that I couldn't have imagined. but on the final, on the final, I want you to, you know, be able to look at the question, and hopefully, it's a relatively factual question and just answer it. of course, a good way to study for the final is to take a look at the quizzes and look at the quizzes you know check the lectures again do quick review. That's why I give you some time. but once you start taking the exam, once you start it, you have 24 hours to finish it. And so, again, thank you. I look forward to seeing your performance on the exam. And I've got a little tiny video right after this. that kind of takes us back to the very beginning. the video of Tim Berners-Lee where he talks about his view of the future. By now, those of you who have done the peer assignment, you've also shared your view of the future. And let's let's go back and take another look at Tim's view of the future. and then after that I have a graduation video where you, we have a graduation speaker and and you can, you know, get your certificate at a real live or at least real virtual graduation ceremony. So the end of a class is sort of, sort of both a celebration. A celebration of achievement, accomplishment. it's good the classes don't last forever. We, we finish them and, and that's always wonderful and fun. but it's also kind of sad. It's kind of sad because we've come together as a community and a group of people. And it's been really wonderful and really special. And I miss it as, as soon as the class is over I can relax, but at the same time, I miss it as well. And hopefully, we'll find something we can do together whether it's you guys taking some other class on Coursera or, or perhaps my, my Python class. and but it has really been an honor and a pleasure having you in class, and I, I thank you for all your time.
