I found this class great for 3 main reasons. Firstly, due to the small class size, you have no extra discussions, and can ask all your questions in class. If Professor Wang does not have the answer, he'll make sure to find the answer before the next class and share it with you. Secondly, I enjoyed his teaching method of writing stuff down on the blackboard, as well as sharing his notes on Canvas. At times in class it could be boring, but Zitian's the boy nonetheless.
Finally, he curves around 40% of the class to -A/A range, which helps out a lot.

The class grading conssits of Participations, weekly Problem Sheets 2 Midterms worth 40% of your grade and a final worth 40% as well.
