Reviews of professor Yuxun Sun

Rating: 1.0/5, difficulty: 5.0/5
This guy can't answer an email if his life depended on it. How does a professor just blatantly ignore emails, especially in a summer class. I am amazed at this guy.

Yuxun was an incredible TA. He explained the material in a very intuitive and eye-opening way. The strategies he showed us in recitation helped me significantly on tests. He was always willing to take questions on anything, and even went out of his way to provide us with extra review materials. If he ever ends up teaching a class, take it.

Just finished the first quiz. On top of him ignoring my emails, the only thing he has are good lectures. Although, that doesn't really matter when the quiz was way harder than the homework and un-related. I can't even imagine what his exams are like. This is why UB should not let TA's teach math summer classes. Gonna be a long month with this dude.

Not accessible outside of class, constantly getting corrected by students, won't post quiz or homework answers, posted practice exam answers and some of them WERE WRONG, posted those solutions the day OF THE EXAM, and on top of all that, this dude has not answered 1 email since the semester started and we're halfway through already. USELESS

Made an account on here just for this "professor." Couldn't agree more with the other 2 reviews from this class. I have sent him 3 emails since the class started and each email thread has multiple follow ups and he hasn't answered one. The homework problems assigned are a joke compared to lecture. The first quiz was a complete joke. TAs are a joke.

This man is on another planet when assigning homework problems. Either that or he went to a different lecture than we did because the homework he assigns up doesn't even come close to what's taught in lectures. I am truly amazed. Don't even get me started on the quizzes.
