CollegeGreat 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.
When I went into this class, I was a little bit spooked by the RMP reviews. However, after a little bit of being in this class, I really like it. Easy lectures and the professor clearly cares about improving and making her class a clear and fair experience. Of course, MATH 4B is going to be difficult, but study and you will be perfectly fine.
Maybe Prof. Wei used a different grading system in the past, but Math 4B in W24 was reasonable. Tests are reasonable, lectures are good, and quizzes are normally reasonable. Lectures can be a bit hard to understand, but she posts everything. Easy to piece together yourself. Would take again over some other math profs. Rating 4 to boost.
