The videos on this page were recorded in class, and they are intended to remind students of some (not all) of the key concepts that we learned together. They are clips of lectures and are not comprehensive or complete lessons of topics and concepts. These videos are intended to help students as they work through questions and assignments on their own. One thing they are NOT intended to do is replace classroom learning - they are a review of some topics - daily attendance, attention and consistent effort are the keys to success.
