Reviews of professor Li Gao

Rating: 1.0/5, difficulty: 4.0/5
Copies incorrectly prepared notes incorrectly onto the whiteboard. If you're in his class, your best bet is to sit in both his lectures and another professor.

Tests will be almost all of your grade. His accent isn't too bad, you should be able to understand most of what he says. Hard class, not an incredible teacher, but he's definitely better than a lot of the others, and actually provides examples in class. No curve or extra credit, so be ready and study a lot for the tests.

I thought he was a great professor. Only grades that really matter are four exam grades and homework grades, pretty easy to follow. As long as you keep up with homework, you'll be fine in this class. He explains the way we can understand better, and the accent isn't really the problem. I'd 100% take him again.

I had professor Li for Calc 3 online and he was surprisingly good. He can draw the 3D shapes well which really helps as this is a very visual subject. There were 4 exams throughout the semester with half multiple choice and half free response. If you attend the lectures and do the practice exams he posts, then this class should be an easy A.

Good luck. Copies notes incorrectly to board that have already been copied incorrectly...

Li is not a great prof, but none of the MATH 251 profs are great. His accent is fun and easy to comprehend. He does make mistakes while working out examples so feel free to call him out on it. The homework takes a lot longer than you think it does so stay on top of that.

Amazing professor! Took for online Calculus 3 and he did a really good job considering the online format. His notes a detailed with the basic steps for each type of problem and is very helpful during office hours. He did well answering students questions during lecture and re-explaining things when needed.

Li Gao was one of my favorite profs I've had for a math class. He is very knowledgeable and will answer every question clearly until it's easy to understand. He makes it clear what is going to be on exams and prepares you well for them. He teaches at a good pace and I would definitely take him again!

I was sick for two weeks and he never emailed me back. I asked him so many times for extra help because I wasnt doing well and it wasnt until I was dropping because I was Failing that he did. He basically told me I wasn't ready for this class and it seemed as if he wasn't really willing to help me get on track. Probably the least caring prof ever.

He is a really good lecturer. His explanations are clear, his notes are organized, and probably most importantly he is really good at drawing visual representations of what he is explaining. His course is not much different than any other Calculus class I've taken. Do every practice problem you can before each exam.
