Xudong is a nice Professor. Very kind to students and good at making difficult concept understandable. You will learn a lot through his class.

Xudong is a great professor. He communicates difficult to understand material very well. However he teaches straight out of the book which is somewhat annoying. His exams are very easy as long as you do the practice exams. Overall his class will teach you a lot without being too difficult if you show up to class.

Excellent professor who made his expectations crystal clear. You will learn a lot, but never feel like he's purposefully excluding information you need to know to do well in the class. Recommended to all those who want to learn a lot of material without being in fear of a bad grade.
