Reviews of professor Yi-Wei Liu

Rating: 4.0/5, difficulty: 4.0/5
He is caring and sweet! Very very nice. Exams are difficult but if you redo all the example problems in lectures, the study guide, and the problem sets then you will ace the exams. Come to his OH for questions! The class is not hard tbh.

Ive taken stats classes before and enjoyed them but this professor made his test so much harder than the work we did in the homeworks and in discussion that I was so lost during the whole quarter. If you asked questions during class he wasnt able to help you either so you were pretty much on your own if you didnt go to the TAs office hours.

Very nice and wants students to do well, but lectures are more statements of content than teaching.

I enjoyed the Statistics class before I take this class, this is Yi-Wei's first teaching and I didn't enjoy it. No online notes/PPT, hard homework, very difficult final. His curve is small and the average for the final is 40 percent. I won't recommend to take this class because no matter how hard you working you will not get a grade you satisfy.

His lecture is clear and he is helpful during office hours. His exams are extremely tricky.
