Reviews of professor Cheon-sig Lee

Rating: 5.0/5, difficulty: 3.0/5
I took Precalculus online. The only material besides the lectures (which go over exercises) was the free openstax textbook, so it was very streamlined. The quizzes consist of questions from the exercises, and the tests are from quizzes. He goes over many exercise questions (sometimes he skips), but he has an accent that could be hard to understand.

I noticed that many students criticize Professor Lee, claiming he is a bad teacher due to his accent and unclear explanations. However, I disagree with these comments. In my experience, Professor Lee is a kind and caring teacher who genuinely cares about his students. If you fail his class, it is likely due to lack of effort. Give it a try trust me

Professor Lee is a great guy but is horrible to teach or follow. The man has a heavy accent that you can't understand. He will skip questions to get everything done on time. I advise you to have Professor Danielle Keenan. She breaks every question down and will ask any question if you need help. The bestProfessor of San Jac. I made an A with her.

PAY ATTENTION TO LECTURES! He goes over every problem!! Lectures are recorded and posted into Blackboard. He is very strict on deadlines unless its a major emergency. What I did that really helped me was write down how to solve each problem on the homeworks so I could look back at them know how to solve them when it was time to test. HELPED ALOT!!!

 Very nice and funny, but extremely hard to learn from. Most questions from his lectures were left unsolved and skipped and I never go to grasp onto it. He did provide other sources and YouTube videos,  but neither of them were taught the same way he taught. So it was like you weren't sure the right way to the answer. It was very frustrating.

Lots of homework and if you don't show work, you get no credit.
