Reviews of professor Xiaofeng Xu

Rating: 1.0/5, difficulty: 5.0/5
Lecture slides are absolutely useless. Attending lecture other than days with in-class assignments is absolutely useless. Test questions are confusing and contain many errors which lead to further confusion. Some test questions contain answers that have clear contradictions with his own slides. Good luck.

Dr. XU is a good statistics prof. He has an accent, but just rewatch the videos if you don't understand the first time. Exam #2 is the hardest. He reviews with us before every exam. There is two exams, final, quizzes (60%) and lab section (40%). He very understanding cuz of covid. Overall, great person and descent lecturer.

He knows a lot about statistics and includes a lot of information and examples on the slides. But it's 60 slides and he reads off them so it can be boring. His accent could be difficult to understand. Lab is using the R program which is the homework. Other than that, no textbook+no homework. There are pop-quizzes, he announces them the day before.

The class is split by two professors. I like Dr Xu better, he teaches clearly and the exam is worded clearly. Lectures are just the book, so memorize it. The class itself is quizzes and tests, all open note open book. The lab is a lot of busy work and a 10 pg research paper. You have to read the book before the exams, they're kind of hard.

 The way he presented the material was not engaging. He mostly read off the slides. Read the textbook to understand better. He was difficult to understand because he did not speak loudly enough. The tests are pretty easy if you listen. The lectures are kind of boring, maybe if you like ecology you'll like it better.
