took his 104A earlier so take this 104B again. getting a good grade is not easy when your TA is tough, but prof himself is not bad. hw is reasonable. if u skip his class, dont skip the review session. the grading policy is so nice. the "drop the lower mid score" literally saves my life. //will write another comment when i finish his 104c.

This professor is extremely straight-forward. The homework for his 104B class wasn't so bad either, especially if you work with your peers. His exams are awesome. He has a review lecture and goes over ALL possible questions he could ask you in the exam and goes over how to do them in detail. It seems pretty counter-intuitive, but I learned a lot.

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)

legendary. Guaranteed A if you go to lectures and put in a little effort.

Prof Xu Yang is very nice and patient. He has review sessions that help us prepare for mid & final, which is SUPER helpful. drop the lowest for one of the hw & one of the mid.

Literally just used another professor's lecture slides and notes.
