First of all, Meier has a very thick German accent and talks very quietly and quickly, so even if you could understand the math, you can't understand what he is saying, so its almost impossible to follow in class. We had quizzes every discussion section, and they were on anything we'd learned up to that point, but never actually related to what we were learning. Same goes for homework. I would spend so much time with classmates or myself trying to figure out what he wanted on written homework, especially since a lot of grading seemed to be arbitrary. Midterms and the final were impossible. The curve on our midterms was so bad that a 55/80 became a B...Basically take it from a different teacher unless you took Calc 3 before, and even then I knew people who were still struggling with material they'd already learned.
