Reviews of professor Luken Zheng

Rating: 3.0/5, difficulty: 4.0/5
Very nice guy, not the best teacher. Slightly hard to understand, and talks quite fast.

I went to his class everyday and asked for help yet I still failed. Attendance is mandatory but it doesnt help your grade. He doesnt lay out what tests are worth up front and I thought I had a C but ended with a 40 but didnt know that until right before the final.

hes a pretty decent teacher. His accent makes it a bit hard to understand sometimes but he's very aware and takes feedback on how to teach better. you have one quiz after each day and it's one question. the tests are 6-8 questions and pretty easy. attendance only counts for one point so attendance isnt necessarly mandatory

Very easy class. He makes statistics understandable and easy.

Going to his class felt pointless because he had his notes online and every assignment and test was online too. Not very good at answering questions so you basically teach yourself but I did learn a lot with the homeworks.
