Reviews of professor Xiao Tang

Rating: 1.0/5, difficulty: 4.0/5
I'm in my fourth year of college and this is the worst professor I've ever had. She changed the textbook requirements for the class two weeks in. Notes are very unclear; some example problems are only half-solved. The organization of her class as well as her answers to questions are very vague and confusing.

This professor is the epitome of unprofessional. Taking this class in person was the worst idea I could have chosen. Lectures were a hodge podge of powerpoints and gibberish written on the white board. It was impossible to follow. Unclear guidelines for every assignment and test, and a unclear schedule that constantly changed. Find another Prof.!

Best teacher, easiest class, made an A with zero trouble. There is one piece of homework per test (4 tests and a final) and all homework can be found online, tests are open and extremely easy. Don't worry about this class.
