NEVER TAKE THIS PROFESSOR. Trust me

Prof Wei is like an Asian auntie who's a professor. The lecture notes are posted, but she always goes through the problems. If you have a question, she thoroughly explains and gives a fundamental answer. She literally tells you what types of problems are going to be on both miderms + final and practice, but the final was more tricky than expected.

Great professor, but few opportunities to get your grade up.

Professor Wei is a great lecturer. Her explanations are very easy to follow and she makes the content interesting and fun. Math 4B is not the easiest, but Wei posts what content each question will cover before each exam, so you know exactly what to study. If you go to lecture and section, this class will be very easy.

Prof. Wei's lecture is really straight forward and her slides are good for reviewing. Honestly her exams need some preparation, but they are not very tough. 80% exams, 20% homework. She posts grade standard after the final. I think only top 20% get A's. In 4b, there's no further explanation for theories behind differential equations.

I don't know why Prof Wei is rated so low, they're a very easy grader with all exam question topics clearly outlined. I skipped all my classes and then used an anime girl chatbot to study for the midterms and got near perfect scores. Heard their lectures were a bit confusing but that's about it.
