CollegeDon't use the practice final to study, you pretty much have to know everything from the sections in the book. Final was one of the hardest finals I've taken at UCSB. Don't think she curves the class
one of the nicest and most helpful profs you will ever have. terrific during OH. class was tough, but she helped everyone on the final. dont worry about the accent.
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.
