Reviews of professor Ning Liao

Rating: 4.0/5, difficulty: 3.0/5
Great professor; will offer feedback and help you with any questions you might have. Be aware of pop quizzes (maybe 1-2), therefore read the first slides of the topic being covered that day. The exams are tough, but he would give you a fair grade. If you are not interested in the topic, you might find it challenging due to the lack of enthusiasm.

I took global changes. I really enjoyed the content of the class, but it was pretty difficult and time consuming. I would say if you are interested in the topic it is definitely an interesting class. But if you don't then its probably not worth it. Liao is helpful and a fair grader. Be prepared for a lot of reading.

Liao is a good professor but the problem is the subject itself. Dont get me wrong he really knows what he is talking about, but the work and class really is hard to follow. So many names and concepts to remember and he gives study guides with way to many things to study that wont be on tests and quizzes. I only took this class because honors
