Easy class if you have prior calc 1 knowledge, but if not get ready to self learn. She respectfully does not teach well and you have to self teach pretty much everything.MATH1231 2026-05-04 22:39:24 +0000 UTC
She is very nice but her study materials were unhelpful, she would put things on the study guide that weren't even on the test, and word the test problems much differently than the study guide. She also moves very fast in class, so if you didn't take calc in high school I would avoid this class. But if you study you have a chance at doing well.CALC1231 2026-04-29 17:36:28 +0000 UTC
grades were hidden by prof. poor communication. not very friendly, often was rude. final worth 40% of grade and tests worth 30% of grade. rest of that is quizzes, homework, and project.BUSINESSCALC 2026-04-16 16:48:06 +0000 UTC
She does not care about her students, when I went to office hours she was very rude and when I did not understand something she said "how can you not understand?? these are the most basic things" she isn't very kind i would avoid her.BUSN1231 2025-11-20 04:08:53 +0000 UTC
This class if very manageable and actual first teacher to teach me how to use my calculator! Professor Bai provides study guides that are very similar to the exam. We have a group project that you can resubmit for better grade. There are 7 exams but she drops your lowest quiz AND test score! Caring professor and accessible outside of class!BUSCAL 2025-04-26 00:51:03 +0000 UTC
There are weekly quizzes for this class and the class is too long for what you learn every class. Sometimes we just sit there waiting for the time to end instead of her letting us leave. She is really bad at explaining the concept and the only helpful resource are the videos posted on how to do the lessons but it's not even her videos.MATH1215 2025-03-27 21:17:50 +0000 UTC
honestly, what was that?? Idk why no one tells you about how bad she is, it really is impossible to learn anything in this class because of how she teaches. I wish I had read the comments here before taking a class with her.CALC 2025-01-15 18:38:19 +0000 UTC
Very straight-shooting teacher. Works lots of examples in class, and gives very straightforward lectures. Not a super showy personality in the classroom, but she's interesting to talk to after class if you'd really like to. Classic good teacher, would take again. (Can be a bit harsh grading quizzes, but she drops the lowest 2)MATH2341 2022-08-14 05:34:52 +0000 UTC
Professor Bai is a nice person, but she is awful at explaining. If you are good at Calc or have previous knowledge, then this might not be too bad. However, if you are average at Calculus, do not take the class with her. Moves quickly, explains badly and very confusing. Do not recommend.CALC4BUSINESS 2021-01-19 05:00:24 +0000 UTC
I'm not sure why her recent ratings are low, but Professor Bai is sweet and interpersonal throughout the lectures despite the online format due to COVID-19. Textbook reading isn't needed as she provides ppt slides and worksheets (which the tests/quizzes are based on) and there aren't any graded hw assignments. Doing textbook problems will save youMATH1241 2020-06-29 18:08:52 +0000 UTC
Took the course as a 2nd year and my class was mainly freshmen. they were sometimes really rude to her, but Professor Bai was a sass master and shut them down. She was very willing to give one-on-one help and allowed you to correct mistakes in your group project for points back. I enjoyed her teaching so much that I took her for MATH 1231 as well.MATH1130 2017-11-19 14:35:45 +0000 UTC
Precalc with her was honestly a huge waste of my tuition money. Yes the class is easy, but maybe a little too easy that it makes it hard to take it seriously and stay on track. She is very condescending if you are a weak math student, and won't reply emails or provide extra help to students outside of very limited office hours.MATH1120 2017-01-17 15:50:46 +0000 UTC
Very unhelpful for those who struggle with math, doesn't reply to emails. Yeah, there tends to be the students who are more math savvy who pretty much just fly through the class and grades in success. She is dull, difficult understand and approach, and has no personality to try and be more approachable. Her explanations are unclear.MATH 2013-06-07 16:41:05 +0000 UTC
She is a solid teacher. Not exactly interesting or the best but definitely teaches you the material. Pay attention, come to class, and if you need it schedule office hours because she doesnt exist on campus otherwise. I suggest read the book if you dont understand then ask in class. She likes questions. She has an accent-meh.CALC01 2011-04-01 09:57:46 +0000 UTC
She'll like you and make an effort to help you if you show up everyday. she was really mean to the kids that didn't show up. She likes students that work hard even if your not particularly skilled. Hard to understand.CALC1200 2010-03-16 16:50:02 +0000 UTC
