Reviews of professor Kuan-Wen Lai

Rating: 5.0/5, difficulty: 4.0/5
Professor Lai was amazing for all three semesters I had him. A bunch of racists in my lecture made fun of his accent constantly but tbh it isn't even that strong and he's a great teacher. He teaches a bit old school, very chalk and blackboard, but he teaches well. Pay attention, do your homework, study hard, and you will be fine.

Oh boy!! Lei is suitable for elementary and middle schools I don't understand why UMass has taken professors like him. I mean his lectures are so unclear, as a matter of fact majority of the class remains absent during his lectures

Had him for 131 and he was not good. The only reason why i'm enrolled in his 233 class is because there was no room in any other sections. I gave up with him after the first week and went to a better professor's lectures. He goes too fast and doesn't explain the material well. The exam 1 average was a 65% if that says anything.

the class itself got harder this semester more content and a discussion. most borning lectures I have ever been to. not understanding. choppy English no explanations. just another example of umass math department.
