Professor Erwin is really knowledgeable about the material. The homework isn't too bad and the quizzes and tests are all from the homework. As long as you do the homework, you'll do fine in the class. The class is scheduled for 3 hours, but he only takes 1-2 hours max and we get the rest of the time to work on the homework, which I appreciate.

Poorly run class if you actually want to learn, not just pass. Basically spent the class writing and solving equations on the board without teaching why. Made mistakes in almost every equation, and instead of correcting them claimed he didn't know what went wrong. Posted lecture notes online but writing was hardly legible. Dropped after 4 lectures.

Only take this math class if you're good at math. If you struggle to follow along or do webassign then this is not the class for you. He is a nice teacher, but for me, the tests and the homework were complicated to understand.
