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.

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.

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!

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