Reviews of professor Changhui Tan

Rating: 4.0/5, difficulty: 4.0/5
The course in itself is hard, but going to lectures will help understand the material. He will give you as many points as he can, and he allows cheat sheets for exams which are as helpful as you make them. He only really uses examples to teach, so it can be hard to put two and two together. The content will require lots of practice problems.

Dr. Tan is a professor who is excited to teach students and is very passionate about mathematics! He provides words of encouragement to students and helps the best he can to give them good grades. Exams are difficult but are  based off of quizzes and we are given the opportunity to create notes for the exams.

Professor Tan is a very nice and understanding man, but his lectures are very hard to follow. He never fully explained the examples he gave. The exams were extremely challenging. Homework was optional, but I suggest that you do it to get more practice. He tries to give you as much credit as he can on exams, so at least attempt the problems.

I think that he is a very fair professor. His lectures can get a little messy and confusing sometimes, but overall he teaches you what you need to know and it is clear what the exams will be on. You also get formula sheets which help a lot. As long as you put time into practicing the material outside of class, you will be okay.

Calc 2 is a very difficult class, but Professor Tan tries his hardest to make sure everyone succeeds. Partial credit, cheat sheets, etc. Lectures are example heavy and I went to many SI sessions for extra practice. Study hard for the exams and at least attempt every problem. HW is not turned in and I didn't do it for most of the semester.

Tan is an amazing dude. Great professor however he can sometimes move through difficult concepts very quickly. Very knowledgeable and wants to work to help you. The exams are very difficult but he is a very fair grader and gives partial credit

He's a really good professor. His quizzes are simple and just the examples he goes over in the previous class. His exams are just the quizzes. You should be able to pass this class and do fairly well as long you attend lectures and take notes.

Dr. Tan is a very kind professor yet a mediocre lecturer who doesn't give good examples. I found his lectures hard to follow and they didn't do a good job of preparing us for the exams. The 'recommended' textbook was the most useless textbook ever. However, Dr. Tan was very flexible and willing to allow us to exceed the time limit on the final.

Dr. Tan is an excellent calc professor. Calc 2 is a very difficult class, however Dr. Tan does his best to make it doable. He allows you to create cheat sheets for both exams and the final. Exams can be difficult however that is to be expected for the subject matter. He is also an extremely flexible grader and generous with partial credit.
