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.

Very kind, Very organized, and Very engaging professor. He puts great effort into making the class interactive and accessible to students from diverse backgrounds. I gained a lot and feel inspired to continue with the linear algebra series, hoping to have him as my instructor again. I highly recommend this professor to other students!

This is my first upper course. I worried about failing this course but prof Zhou asked us to focus on learning fundamental. In the end, he curved generously. 59% of weight grades get C.

This class was really tough for me, but Professor Zhou did an amazing job explaining all the complicated terms and was super generous with grading. Plus, he is such a kind person that I never felt nervous about asking “silly” questions about basic math stuff during office hours. Hard class, but an awesome professor!

Honestly nothing to complain about. You're expected to know lecture + textbook content and that's what's on the exams. Exams consistently averaged 50-60% but curved GENEROUSLY at the end.

Well-organized lectures and clear explanations. Give make-up points for midterms. Put efforts and time to help students understand course materials.
