Please fill out this form from time to time -- ideally, at the end of each lab, or at the end of each day's class. This is a convenient way for me to keep track, day by day, of what my students are "getting" and what they're not. Your answers to these questions have no impact on your grade (indeed, you're not required to give your name); please be as honest as possible so I can discover and remedy misunderstandings quickly.
