I loved him. He does have an accent, but after a day or two I could understand him perfectly. The tests are fairly difficult, but if you'll actually do the homework it's really not so bad. If you'll make a point of asking him homework questions then he'll answer them, but he doesn't do a "homework review." I had an overall positive experience!

Yeah if you hadn't gotten the point yet don't take this class, dude's stuck in the past, when you go on OSM he's been teaching the class since 2006 so how he still hasn't developed a style that is in any way cohesive or clear to the students is baffling. It's almost like he doesn't understand it himself - blatant regurgitation w/ no commentary, 0/5

Pretty much the same as what the other reviews said for his MATH 420 class. The class was set up in a very confusing way, the information is not presented in a way that is easily understandable, and it is unnecessarily difficult to figure out how well you're doing in the class and if whether or not you understand the material. Avoid if possible.

Sun gets a lot of grief for being a tough professor for MATH420, but I'm not sure it was him or the material. He taught some things very nicely, but struggled with others and wasn't helpful when asking for help. So either you understood or you didn't and had to find help online. His homework took awhile, but it wasn't completely unreasonable.

This course was needlessly harder than it needed to be. You are on your own for the homework assignments. The Dr. Sun's notes are next to useless, and tests are graded very harshly. Min Sun is a nice guy, but he expects you to already know the content before coming to class. Do not take unless you have to, this is not an easy class.

Min Sun seems like a nice guy but expects you to already know most things about probability coming into the class. We had 2 tests and a final we do get extra credit but with the way he grades, you would never know how well you actually did. The course was harder than it should have been and the textbook did not help. Overall Do not take this class.

I love Min Sun. Class is challenging, but that is as expected. Helped me catch up to be best of his ability when I was struggling with my mental health. I didn't do well but that was totally on me.

The worst class I have taken. He can't explain anything, gives lots of HW. However, he is pretty linear while grading and try to get good scores on HW and go to class everyday as there is extra credit for full attendance. Will never take class with him.

NEVER take 420 or 421 with Sun. He is the WORST professor I have EVER had. Reads straight from textbook with little commentary never explains anything shames you for asking questions. This class single handedly destroyed my mental health and confidence in math ability. Entirely proofs. SAVE YOURSELF AND TAKE LITERALLY ANY OTHER CLASS

If you care about proofs and understanding the math you're working with, he's great. Additionally, the course is well structured in terms of homework, which build both theoretical and practical skills with different concepts, and tests are mostly based on the homework. His feedback is less helpful. You will struggle if proofs aren't your thing.

Perfectly good prof for MATH237. Gave plenty of extra credit and even provided us with notes before class. Very generous grading on tests and projects. He sometimes struggles with english/understanding questions which may frustrate some people but he was a good professor.

I expected Min Sun's class to be tough, but the challenge really depended on my own effort. His accent can be a little hard to follow at times, but his lectures are clear, organized, and you can tell he truly enjoys teaching and wants students to succeed. Tests are fair, like the homework, and he's generous with partial credit. He's also hilarious.

I was originally worried going into the course, but Dr. Sun made it really easy to understand the content! His notes can be a bit confusing but they made a lot of sense! You get a formula card on the exams. Study his study guides and homework questions and you will do well.

Professor Min Sun was not the easiest to understand but he definitely knows his stuff. However, if I wasn't already familiar with much of the course work, I don't think my final grade would have been as high. He gives reviews before the tests and the tests are pretty much always easier than the homework problems.

He's a fine guy. He's nice enough but not great at teaching calculus. You can tell he knows what he's talking about but is not good at explaining. By the end of the semester I only showed up to class for the bonus points for attendance. If you're willing to take the time to learn it outside of the class room you'll do fine though.

Sometimes a bit of communication difficulties, but overall, he was a solid professor for the course. There is a good bit of homework, but that homework certainly makes the tests a breeze. He does explicitly say to read the textbook and offers many extra credit opportunities (e.g. through attendance).
