Reviews of professor Cheon-sig Lee

Rating: 1.0/5, difficulty: 4.0/5
This professor is not worth the class. He is obviously a very smart individual, but he is not good at actually teaching that intelligence. Comparing his speed versus other teachers, he rushes through everything and even if obviously no one gets it, he just says that we need to look it up ourselves. Heavy accent, no extra credit, and very demeaning.

Prof. Lee has a thick accent, you can't understand anything he says. He is consistently off topic, usually bantering his own students. He is not professional at all, does not clearly explain topics, sets you up for failure. I was forced to ignore his unusable lectures, self teach, and pay for lots of 1 on 1 third party tutoring just to pass.

He's a good teacher. The test are a bit difficult, and you get a lot of homework, but his lectures are easy to understand, and are very interesting.
