Professor Zheng knows the material very well and provided solid examples of how to do specific problems in each topic. I feel like he had a good course schedule of chapters and worked his way through each section efficiently. He was adept with Zoom from day one, asked for frequent student input, and developed an equitable, straight-scale grading format that was fair and well-suited for remote learning. The professor really cared about us learning the course material, and he shared a lot of his interesting research that related to the content learned in class, which was fun. I cannot recommend Professor Zheng enough, and I would happily take another course with him.
