She is really hard to understand. (Heavy Chinese accent) Lecture is pointless. Powerpoint slides are redundant, and she hardly elaborates on difficult concepts. When she does elaborate she writes on the white board with an already dried up marker and in the tiniest handwriting. I was shocked at, what seemed to be, her lack of wanting to teach.

Professor Liao has an incredibly heavy accent. I cannot understand her at all. She should not be a professor. The slides are very repetitive, simply stating formulas over and over. I cannot understand her, and the slides are not sufficient to learn from on their own. Her work on the board is feint and tiny. Overall, very poor learning experience.

She does not know how to teach.

Professor Liao clearly introduces new concepts and provides amble examples for every new piece. She's amazingly organized and thorough in her presentation. She also has a really chill, fun personality. If you're into stats and you want to really learn, take her class. She's a rockstar.

At beginging of the class, you may doubout whether she is good enough to teach students, while the longer you take her classes, you will like her more. Very logical lecture notes, the course it self may be difficult by itself but with her detailed and well-organized instruction, it becomes easy understood, the test is easy, practial test provided.

She acts and talks like a zombie so that normal humans can hardly stay focus on her classes. However, she has good lecture slides and really easy finals(exact the same as the practice final).
