Honestly, his lectures were not even bad. He genuinely cares about his students and is very passionate about math. His tests and stuff weren't even hard. If you pay attention in the lecture where he goes over examples then you will be set. I think all the bad reviews are just salty people who didn't get a good grade.

hard to understand with his thick accent. his notes are one of the worst ive seen. I dreaded this class and the way he taught linear algebra. Avoid this man unless you are korean and understand his accent.

He's really sweet and tests and HW are reasonable, lectures and notes are definitely a bit scattered and messy but overall had a good time.

He made his class a lot harder than last quarter. His notes were terrible and his lectures were a pain to sit through. He also doesn't provide an answer key for his study guides in order to "relieve stress" on the students. Overall, the homework and quizzes were pretty easy and the tests were fair for the most part.

He was sweet and tried making himself available, but he always went off on a tangent which made it frustrating to write notes. The grade consisted of many things such as iClicker, Quizzes (in class), and the Exams. Section attendance wasn't mandatory, so I stopped showing up. Had Webwork due before every lecture too.

Fairly easy homework and quizzes. Study practice exams and you will be fine on the midterms and final. Very cool person and extremely nice professor.
