She's nice but her lectures are unclear. If you've taken calculus before, you'll do well. If you haven't, prepare to do a lot of self-learning. The directions for the final presentation are unclear. She told my group we did it wrong, so the other groups changed their projects according to what she told us, but still told them they did it wrong.

Rekha is a very good professor, I would say I am willing to take her course again so many time. I like her teaching style, she will show you the definition of sth and then go through enough examples to help you understand it. I like her class so much. I could say she inspired me a lot on math, and I change my major to math after taking her class.

Taking calc with her will be your worst nightmare if you have never taken calculus before/if you are an international student. Professor has a very hard to understand accent, so you have to do a lot of self-learning. She covers the material in class very quickly and you can't join the class online; wouldn't help you if you are struggling in class.

Professor Bai is a really sweet and caring professor. Unfortunately, I just failed to understand her lectures, even as someone who took calculus in high school. She goes really fast and I can never write notes fast enough to keep up with her. If you zone out for even a second, she's already explained two topics and moved onto the next.

if you've taken calc before, it is very doable and honestly shouldn't be that hard. Her lectures were useless to me so I stopped going and relied heavily on the textbook to learn. Her quizzes are usually 15 minutes and 5 questions. Grade is heavily relied on the weekly quizzes and final.

Dr. Bai is very caring, wants to see her students succeed in class, and she uploads the lecture notes on Canvas. Not a difficult class if you've taken Calc in high school. Quizzes every week (40% of your grade), 20 points each, 1 midterm and 1 final exam. However, she moves too fast on important topics sometimes. All/most exams graded by her TA.

terrible at teaching w/ a heavy accent. goes too fast. If you leave for 5 mins she literally jumped 5 topics ahead. Quizzes every week, She moves onto the next topic before the quiz. Some of the things on the quizzes isn't even taught. Grade only depends on exams. Office hours didn't help. She includes Calc 2 & 3 into a Calc 1 course for business.

Do not take if you've never taken pre-calc or calc before. She's hard to understand and moves onto different topics really fast. Quizzes (no calculator) are in the first 15 mins of class and tests are 45 mins. The examples done in class jump from 0 to 100 on the actual tests. I've never felt so dumb as much as I do sitting in that class...

Honestly, if you're anxious about math or calc, this class is HARD. I am struggling so much. She doesn't answer questions directly, instead says "we covered it in class." The final (cummulative) is worth 40% which I think is abismal. Idk if all professors are teaching the concepts she is, but it honestly all seems more complicated than it should.

I don't understand the negative reviews! She is very patient and open to answer questions. As someone who isn't naturally great in math, I found this class one of the best I've taken.
