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.

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.

The lectures were clear and engaging, significantly enhancing my comprehension of the material. Additionally, Prof Zhou's generosity with extra credit opportunities reflected a sincere commitment to student success.

Excellent teaching. Patient and welcoming to students' questions, and explain concepts in detail. He motivates students to really understand the concepts instead of memorizing them. These negative comments are only due to the difficulty of his exam, but he made it clear from the start that there won't be repetitive questions. Will take again.

Excellent in teaching. Patient, welcoming students' questions, and put efforts in lectures to explain concepts in detail. He motivates students to really understand the concepts instead of memorizing them. Negative comments are only due to the difficulty of his exam, but he made it clear from the start that there won't be any repetitive questions.

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.

Really accessible after class and kind, you can always attend his OH, and he's willing to help. You can get bonus points for midterms by presenting in class or in OH. Lectures make the textbook more understandable.

Professor Zhou is a very kind person, and I can tell he really wants his students to succeed. He lectures by doing problems on lecture notes. The class was easy and the practice tests provided were very helpful. I definitely recommend professor Zhou's class.

I had a hard time because I did not find his lectures engaging. However, he was willing to adjust his plan for the class in order to help us succeed. I think he was very kind but I would avoid taking his class in the future if I can.

I really appreciated the course's structure. The professor delivered detailed, clear lectures that made tough concepts manageable and provided a solid foundation for homework and exams. He was also highly accessible for help outside class.

I really did appreciate how kind Prof. Zhou was and how open he was to making changes to the course/exams in order to help the class succeed.
