Reviews of professor Changjian Su

Rating: 1.0/5, difficulty: 4.0/5
Get ready to read, there isn't much information he conveys clearly in class. He doesn't write very much at all. His teaching style consisting of flipping through pre-prepared slideshows without allowing you time to read what is on each slide.

Rating: 4.0/5, difficulty: 3.0/5
He's new, but he tried his best and is not a bad instructor. He can be very jittery and has a heavy accent, which sometimes made it hard to understand what he's saying, but he'll clarify if you ask him.

Must have for MAT 135.

He is nice and approachable. When I took the course in Winter 2019 he was pretty new and seemed pretty nervous when teaching so he didn't always explain things clearly, but I could also tell that he is putting in his best effort and is willing to help students when asked. I remember the tests had some hard questions but not his fault.

Prof. Su isn't the best prof but compared to the other instructors for 2020 MAT244? He is the best. Although, he also just reads from the slides that Dr. Ivrii prepares. He has a thick accent but I can understand him fine. He doesn't make the tests so can't comment on that.

He has a heavy-ish accent but demonstrates great passion to teach and make us understand the material. New teacher, very nervous and stutter at times but puts enormous amount of effort into trying to make us understand.

I was completely unable to understand him, speaks very quietly and quickly with a very thick accent while facing the board.
