Unless there is a pop quiz all you are graded on is tests and the quizzes are few and fairly easy to predict. The only way he can be tricky is if you have to miss class for something like hospitalization. He is very unhelpful for telling you what you will miss and need to do even if you see him ahead of time. Otherwise he is probably the best.

Mr. Lim explains the material very clearly. All you need to do is attend class and carefully write down everything he puts on the board. His exams closely match the notes, and if you study the problems he explains in class, you can expect similar questions on the test. He gives homework to help us study, not to turn in. He is an excellent teacher.
