Reviews of professor Hyunju Ban

Rating: 1.0/5, difficulty: 5.0/5
Atrocious professor. Not one redeeming factor about him. He is an extremely tough grader, awful at explaining and teaching all around, and just a joke. Don't waste your time taking his class you'll just end up dropping it.

Absolutely awful experience, if people think that Calculus was already difficult, this professor makes it impossible. I had made all the stops to try and succeed, even enlisting help from graduate-level tutors who even found this professor's grading system and methods ridiculous! Take this review and others to heart and avoid his classes all costs.

Took this class in summer. The exams where very well balanced and appropriate to the course material. Final exam is very difficult. Professor is definitely a tough grader. But you don't need to get a question fully right to earn plenty of points. I personally like the show your work questions because you can get points even if the answer is wrong.

I'm withdrawing from this class as a math major. There is so much content for this class, I literally had spent all of 2 weeks studying multiple hours a day and it was still not enough. The tests require you to know so much info (the obscurest of stuff from sections) and for 4 weeks, it's just not possible to succeed. My advice, DROP! not worth it

He goes over 2-3 subchapters a day and doesn't convey the material in a way most students would understand. Expect to only learn about 5% of the material in class and the rest at home through self learning. Either avoid this professor or only take this class for the semester. This is basically a self taught class with this person. Goodluck.

I wouldn't recommend for anyone who is average at math that is needed to pass. He storms through lectures and people are so confused, they can't come up with a question to ask. He doesn't allow a graphing calc, he gives you his formula sheet with formulas you hardly ever use. Focus on the textbook examples and homework and quizzes.

Do not take this class if you value your mental health. He does not curve, when you ask questions he never lets you finish, doesn't respond to emails, goes over questions in an off-brand Zoom called Cisco-Webex that aren't even questions tested over. If you take this class, good luck and be sure you do all the homeworks and discussion board posts.
