Reviews of professor Liyan Yang

Rating: 5.0/5, difficulty: 3.0/5
This professor is very very good at teaching, who can always illustrate the concepts in a very easy way. Be ready to do math in his class!

Its been 5 weeks, I haven't gotten anything back yet, nor done a midterm. BUT he is unbearable, I can't understand what he says with his accent (and im literally Chinese), and ive learned nothing and can't do the assignments. His lectures are all over the place.

It's nearly impossible to get a high grade in his class unless you are talented and good at self-study because his class was unorganized, he was irresponsible for the lecture content. No detailed explanation and the pace was really fast. The first time that I think carefully choosing a professor is so important...

The lecture delivery was awful. He rarely stuck to his slides; he projected his OneNote and taught by drawing ineligible equations and drawings, and he often introduced topics without a clear explanation. His English was not the greatest, which made his lectures even harder to follow. I strongly advise taking ANY other professor.

This professor was not good. I, unfortunately, could not understand nor keep up with the lectures he put out. I had to rely on another professor's recorded live lectures to save my grade (thank god).

This was the most unorganized class I've ever taken, and I took ECO204 last year. Basically everything you are graded on is a group project, so you better hope your group members pull their weight. You are being taught by two profs with live/recorded lectures and have no idea which to rely on for quizzes, which also make no sense. Take anyone else!
