> When I was in college I would zone out in lecture and wait till I got home to do the homework because I was being graded on homework and exams

1) College is very different from high school

2) If you don't need the lecturer, then the lecturer sucks.

3) If you really understand that well, why come (I can only assume they took attendance)? I had a digital logical class that was required, but I didn't bother showing up and scored 150%. When I lecture, if you don't need to be there, don't show up. That's perfectly fine by me. However, don't expect me to have a lot of sympathy if you suddenly find that you don't really understand what I lectured on that you skipped.
