Mrs Wang is a grad student that taught 33A Spring 2019. I personally liked Stephanie and did rly well in her class, however I must admit it is not an easy class. Stephanie's teaching style is very in depth and very fast. She will often give you very technical definitions of every theorem, sometimes with insufficient explanation so you are often left confused with a whole board of writing. There have been many times where no one in the class understood what she had just proven. However, her homework, while long and hard, is helpful with understanding the material. However, her quizzes are very fair. To study for the midterms and finals, I reviewed the quiz and hw solutions and that helped me a lot with the test. If you can understand Stephanie's lecture, you will be very knowledgeable of the material and do well.
