Professor makes a bad first impression, was tempted to drop on first day. But, his accent is only a problem the first day, and he teaches things very clearly. You can choose to have homework included if it benefits your grade. Very comforting environment, ended up really enjoying the class and it really changed the way I think.

Took him for Math 3A and he made it almost unnecessarily difficult to understand any concept. His accent is incredibly heavy making him nearly impossible to understand. He doesn't really know how to teach, he just starts writing on the chalkboard and doesn't explain anything. After writing something down he won't explain, and just say "y'know?"

Heavy accent and doesn't really explain things well. as others have said he copies notes/lectures from another prof and often presents incorrect information. Hw takes FOREVER to do and is very code-heavy, pain in the behind tbh. exams are pretty difficult and relies on memorization of concepts. overall do not recommend (i also took 104b with yang)

will 100% take again (ill fail)

Very difficult to understand, and unhelpful.

Professor Yang was nearly impossible to understand verbally. He would also start progressively shouting towards the end of class which gave me headaches. He didn't teach necessary math8 concepts like truth tables or different types of proof. You just copy his examples and memorize them temporarily for a good exam grade. DONT TAKE, save your sanity.
