By far the worst professor I've had. The lectures were all over the place; he just rambled off with little structure. The sections were poorly planned. There would be content in the quizzes that he had not covered yet. He does not follow the textbook at all, so it is very hard to learn outside of class.

Attendance is mandatory and notes are messy, but other than that I really loved Cho for the first 9 weeks of class. Then, after telling us our final was NOT cumulative and giving a clear practice final, he gave an unrelated, cumulative final... Really blindsided the whole class after everyone felt like they were doing really well til that point

I don't get all the bad reviews. Yes, he speaks fast, but it doesn't bother me. I really enjoyed his class. Have a good summer!

It is impossible to understand him becuase he speaks so fast. Does not respond to emails and gives tricky questions on exams. Lectures are very disorganized. I don't get the hype about him. Don't take any class with him ever.

Excellent professor. Didn't have to self-study for a single topic. Midterm was easy. Final was not cumulative, but might be normally, still easy. Homework was very light, 6 WW sets. Attendance thru iClicker. Shows cat pictures. Funny guy. Talks very quick and can be hard to keep up with. Still recommend highly. My favorite math prof so far.

He is an absolute gem in the UCSB math department. Seriously. Really reminds me of my high school teachers that actually explain the contents rather than providing a sloppy PowerPoint. This is probably the first math class where I don't need to search up how to do a problem. He is that good. Exams may be difficult but graded leniently.

He had beat 99% professors by recording his lecture diligently and upload it to Gauchospace every single of time. If you like math, take him, as he is willing to share some advanced topics that are fun. If you don't like math, take him, because he will share his cute cat and his personal life in between tough contents.

Explains things very well and makes even difficult concepts make sense. He also uploaded all the lectures on his Youtube:)

Lectures are very organized and teach the content well. However, he talks really fast and it might be hard to digest the content at times, which is why you need to review your notes. His exams are quite similar to the practice ones, but he'll throw in a challenging question that might be unfamiliar. He's the best lecturer I've had.

He's a genius and also knows how to teach. Please take a class with him if you have an opportunity. He records lectures and posts them right away lecture. The practice exams are identical to the real exams. Be aware of weekly quizzes in section.

THIS IS THE GREATEST PROFESSOR, in essence he's the same as that really good high school professor you had. Very dedicated to teaching and very engaging even when the content is a little slow (he showed pictures of his cats). I genuinely think maybe the best math professor on campus.

He is by far the best maths professor I have had so far here

He teaches way more useful thing than other instructors for this course. This was really stressing, but I also learnt a lot. I was worrying if I could get an A the whole time, since he said that the course may not be curved. However, in the end he still gave a curve. He is also very helpful and supportive, though sometimes not that patient.

He is my fav prof! He talks very fast but I had no problem understanding him.

I liked his lectures (funny guy), light homework, and tests weren't too difficult, but he'll often try to trick students, purposely writing misleading answers on practice test solutions to trick those who don't pay attention in lecture. Spent hours figuring out why my answers didn't line up with his... turns out he just wrote it wrong on purpose.

cool and caring guy, definitely recommend his class

Uses webwork, tests are pretty similar to practice tests. Final has some trick questions on it. Lectures aren't mandatory but they might as well be. He talks incredibly fast and covers a TON of material in 75 minutes, so you need to go otherwise you'll fall behind

I took him over the strike. 1st midterm was in-person and was so easy, literally like a 89% average or something. 2nd midterm and final were both on Webwork, unlimited attempts. He was genuinely such a nice guy, only tested us basically on word for word examples (even in person) and made the lecture at least somewhat bearable.

The goat

very fair grader. I took his class during the ta strike so things got a little messed up but overall a good class. the material at the end of the quarter felt a little rushed tho. very kind professor and shows cat pictures during lectures!!!

Professor Cho is very respectable and extremely caring about his students. While his lectures can be hard to follow, his homework is fair and he does give out practice for his exams. Got lucky because 2 exams were moved online due to the strike, but his physical in-person exams are hard and proof-based. Nice grader though, and super caring!

If you don't miss his class, you will get an A.

He is an alright professor and probably on the better end for the math department. His lectures seem lengthy and sometimes starts talking about things you never need to learn. He gives practice tests that are very similar to his real tests and he gives decent partial credit. Overall average professor.

Cho's exams are similar to homework and practice problems. There are quizzes during sections, so you don't want to miss them. Cho speaks very fast, so it is hard to follow sometimes, but generally his lectures are helpful.
