It was a really hard class for me, but Professor Zhou explained the difficult concepts really well and was very fair with grading. He's also super kind, so students feel comfortable asking questions. Tough class, but an awesome professor!

Zhou teaches SOOO slowly and spends entire lectures on review, but doesn't cover the material he's supposed to. I only took 6B for the PDEs, which he didn't even get CLOSE to going over by the end >:( He does give a lot of extra credit, so if you want an A or are shaky on basic vector calc, he's fine-- but if you want rigor, look elsewhere.

Really wish to continue the series taught by Prof. Zhou. Seems he is not teaching this quarter. He is my GOAT.

love him #king

When I was looking into rate of my professor in grad school, I realized how much I appreciate Prof. Zhou. He always took the time to answer my questions until everything made sense. His constant encouragement and reminders not to doubt myself really boosted my confidence and kept me going on my path to grad school.

Everyone says 6B's kinda weird — most profs just speed-run vector calc and then randomly jump into series with zero connection. But honestly, Prof. Zhou made the class super chill and actually fun. His lectures were kinda slow sometimes, but I feel like I finally get vector calc now. Plus, the math activities were pretty entertaining

His lectures do what lectures do except his class is so slow we end up not covering Fourier series like some of the past cohorts. His exams are easy but unoriginal and uncreative, they become merely a linear combination of regurgitating facts. The worst thing? Bro uses \overrightarrow{} (not even \vec{}!) to represent UNIT vectors. As a math prof.

I have no comment on the teaching because I did not attend any lectures but the material was so easy and the exams were really straightforward. Attendance was taken purely for extra credit and you could earn up to 8% of extra credit towards the final grade outside of attendance too. Seems like a very nice guy too.

Doing the midterm reflections was a great chance to learn and hear different perspectives. It really helped create a supportive environment IMO.

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

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

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.
