Reviews of professor Jiangwen Sun

Rating: 1.0/5, difficulty: 5.0/5
This professor honestly made me wonder why he was getting paid. He uses the same Zeil lectures and assignments and does nothing to expand on them. He did nothing throughout the entirety of the course aside from timely email responses with vague relation to a question being asked. Don't take this professor, you will be learning it by yourself.

He is basically Professor Zeil. They use the same course website and materials.
