I have biochemistry every weekday at 8am in the morning because my professor is just cruel like that (though he's really good at teaching). We just finished learning about the electron transport chain.
Though his exams aren't so bad, since he tends to recycle questions from his quizzes (that essentially don't count as long as we take all of them and we do well on the exams).
He finds it amusing that he gets so many negative reviews each quarter though.
Yeah, my professor is a bit crazy. She has constant typos in her notes. While this isn't bad, she usually backs it up with an excuse like, "Oh...it was late when I was doing this" or "Oh, this is what happens when you copy and paste."
I do not give a rat's ass if you make a typo or mistake. Just TELL US and say "Sorry, there's a typo". I don't need a bloody excuse.
