Nice professor. Contents are well–organized and explanation are clear.

He is always caring for students and willing to help them. Exams are somewhat difficult but he offers bonus points as long as you would like to put efforts.

His low reviews are just people who have low grades. Yes his exams are difficult and he actually grades your homework on accuracy but you get what you put into the class. Prof Zhou is amazing and I would take his class if the opportunity ever arises again.

Couldn't ask for more in a professor. Explained everything you needed to know, and the homework and exams weren't too bad.

Dr. Zhou is super accessible outside of class in office hours. His midterm extra credit is helpful, and his in depth study guides make sure students know the general flavor of exams. He will never give you a problem you have seen before on an exam, but with studying, they are certainly do-able.

its a really hard class but prof zhou is super understanding, is willing to help you understand the material, and is very accessible outside of lectures. he also offered extra credit opportunities for the midterms by doing reflections and presentations.
