Class is definitely very test heavy, exams are worth a lot and composed of few problems. Homework sets vary in difficulty. Some problems are relatively easy and quick and others are incredibly long and frustrating. It is hard to get a perfect grade on those but that is more than okay with him since the curve is generally pretty generous.

He is not good at explaining things and the lecture notes are not organized. Also, his accent is pretty hard to understand.

Good Lecturer. You can tell he really enjoys what he teaches. The tests are difficult, but the curve is generous. Just spend a lot of time truly understanding the homework problems.

Very hard class and he's not very good at explaining things.

Campas' class is a difficult one. He is a super smart professor and you're best off to take his advice and really grind through, spending HOURS on one homework problem to actually understand it otherwise you likely won't succeed. Difficulty aside, Campas is a great professor and he really does want you to succeed. DO THE HOMEWORK.

It's a hard class. Campas explains well. Do the homework problems, sometimes he put some in tests
