Interactive video notes

I will create interactive videos to teach you the material of this course going forward. We will go over this video together. In it will be videos explaining the new material, followed by questions you have to answer to show you understand. Completing this is work 100 points and you must get at least half the questions right. You can open the completed notes if you would like to help you.
