Reviews of professor Xiaofeng Xu

Rating: 5.0/5, difficulty: 3.0/5
I thought Dr. Xu was an amazing professor, really caring for the students. He covers all aspects of content and gives us feedbacks and take home questions to help understand content. His study guides are incredibly helpful. His lectures are fun and easy.

Dr. Xu's lectures were amazing. Lots of content covered, good for learning and bad for exams. His accent is a minor problem, but it is clear enough to understand everything. Investing time to learn will earn you a decent grade.

Prof Xu is a very nice person with a strong quantitative knowledge base for stat. The lectures were clear, and the questions were fair. Come to class and ask questions you have. He is always available outside of class. Email and set up appointments to ask specific questions on the exam and he will explain it very well.

Read the textbook and you'll be fine. Dr. Xu's lectures are understandable, but he also tests on (assigned) readings that he sometimes doesn't cover in class. He was very nice and even let us decide on exam formats. Evidently, the people complaining about his accent are just xenophobes making excuses for not studying or reading the textbook.
