Comment:

I took Choi for Calc1. He's a nice guy, but gives a lot of homework from the textbook, he lectures quickly straight from the textbook w/o really explaining the material. If you want to actually learn in this class, you have to teach yourself. His accent is pretty thick & there is a genuine language barrier. I wouldn't take a class with him again :/

Yikes. Line up your textbook and your tutors because you'll likely need them. The thick accent makes learning a difficult topic even more stressful, and essentially you'll be teaching yourself here. He cares but explains everything quickly and gives lots of ungraded homework. Tests can be pretty difficult and are worth the majority of your grade.

Comment:

Professor Choi was one of the worst teachers I've ever had. he gave terrible lectures, and gave up on them half way through. His "lectures" were him reading directly, poorly from the text. When he stopped giving lectures he would expect us to figure the topics out on our own. I hate to say this, but there was a genuine language barrier. STAY AWAY!!

Goes over material too quickly in class and does not take the time to explain what's going on. If you miss even one class you are so behind and it's impossible to catch up. Do not take him. I received 100% on my homework but struggled with the tests and finals. Failed me by 2 points. Horrible teacher.

If you're not doing well in math don't take this dude. He's a nice guy but sucks at teaching. Every time I needed extra help he gave me nothing. I went to the support center and in the 10 minutes there I understood more than in one of his class lectures. Totally sucks.

DO NOT TAKE HIM FOR AN ONLINE CLASS I spent hours and hours and hours doing hundreds of MML questions every single night. way WAY too much homework. His notes are useless and doesn't give good feedback on forums.

Comment:

Everyone in my class hated him. I for one enjoyed his class. He gives very hard problems and I think if you are going into STEM, you should take him. Do problems that are not even assigned because the extra practice will benefit you in the long run. Read your textbook. Calculus is learned through practice.

Comment:

Guy tries to be nice by offering his class food or coffee. He uses that as a replacement for the time and effort he should be putting into lectures and grading. He marked answers wrong on a test when they were clearly correct. Hard to understand him sometimes and was a waste of time to show up to lectures. He would go over book problems on a slide.

Comment:

The WORST professor I have ever had. If you're not as good in math, like myself, then do not take any classes he teaches. He goes so fast in the lectures and if you get behind, it's your problem and he has limited sources to help you and give extra help. Spare yourself the stress and take a different class.

If you failed this class, it's probably because you do suck at math. He helped me a lot. This class was by your own pace. So you can't really fail unless, you are really really stupid. Also he lets you re take test till you pass with a good grade. (Note: I didn't try hard and got a B. So yeah)

Comment:

He made it very hard to pass this class. Put in min effort but expected beyond max effort from students.This class is 100% selftaught and the exams were too hard.The final exam guidance was to know how to do the 161 hw problems assigned.I LOVE math and this class was still a huge challenge.Do not take him online if you're looking for a fair course.

Professor Choi is great professor. Thorough with explaining any questions. Funny guy too! Be sure to do your part by doing your homework and reviewing the lectures he assigns in the syllabus and this course is incredibly simple. I got an A+ in the class but I found that my classmates who were having trouble did not prepare themselves before class.

Took online diff eq w/ him. He didn't teach and only used YouTube videos from other people. It's an online class which requires self direction. However, he didn't provide any instruction. Exams are fair and he tells you topics covered for each question. Doesn't have office hours.
