Terrible lectures and section don't bother attending he really does not know how to teach. Ridiculously hard midterm and final. My advice switch professors or take it a different quarter just avoid him.

I came back to write a review after taking 120B again this quarter with a different professor and honestly this material is easy Oh made it unnecessarily hard. He is bottom line a horrible professor: lectures are confusing, homework is graded way too toughly, midterms were extremely difficult for no reason. You'll regret it if you take 120B with Oh

Very poor professor, really failed to make concepts clear or explain the subject well. Homework was graded way too toughly instead of checking for completeness and effort. The midterm average was far below failing and yet there was no curve. Final was unfair as well. Bottom line don't take this professor. Got an A in 120 just to fail this class.

VERY HARD professor. I got an A in 120A and I had no idea what he was talking about half the time. His midterm had a class average of far below failing, unreasonably hard tests, difficult to follow during lecture. Very nice guy though, he is definitely just new and trying

DO NOT take courses of this professor Exam was verrrrrry hard and grade was given toughly even if you work really hard

His lectures are often boring but he does go through a lot of examples. The homeworks are really hard but are also much more difficult than the exams. He's a young guy so will probably (hopefully) get better.

The lectures were unclear at times, however, Oh is extremely helpful in clarifying topics in office hours. Oh gets a bad rap from students who most likely didn't put in the time to read and go to office hours. Read the book, ask questions, go to s office hours, and you'll do fine. Don't expect a good grade if you aren't willing to work for it...

The class is extremely tough. He moves very quickly in the lectures and it's hard to keep up, and a lot of it relies on you already knowing most of the definitions and theorems in 120A. He's a nice guy though, but the lecture and the material is dry and difficult.

This is a pointlessly difficult class. The professor is a nice guy, but is new to teaching. He doesn't know how to explain examples while he is doing them, and assumes the students are already familiar with the terminology. The midterm average was around a 34%. There is no way to pass this class with out reading very thoroughly and analytically.

He looks nice and he is a nice person. This is his first time teaching and the midterm average is like 30 % something, it scars most of the people. the lecture is useless you pretty much study on your own , there is like no point to go to his class. think twice before you take it.

Terrible lecturer. Tests are impossibly hard. The class average on the midterm was a 30% and the highest grade was a C. Lectures are irrevlant to subject matter and the material is really difficult. He is a really approachable and friendly guy so it's shame that he is so poor at teaching. I don't not recommend taking him.

Useless lecture. not making any sense. You have to study on your own and test is totally irrelevant with homework or lecture.

Sang is a considerate professor, and taught the course content in a useful, albeit monotonous fashion. A lot of new content to cover than most PSTAT courses, with weekly quizzes in lecture (open note!) and pointless sections, and while assignments were certainly doable some programs chosen were quite difficult to work with (especially the project).

Lectures were very slow and dry. Content seemed disorganized and jumped around topics week by week. Quiz every Thursday in person at the end of class. And there was a final group project, but it was just really tedious because of the online system we had to use. Overall very disappointing for a class I thought would be really interesting.

Very bad and boring lectures. Do not take this professor if you actually want to learn anything.

the way the class is weighted it is easy to get a good grade without doing that much however class was so boring i did not learn anything in class and I was confused all quarter long. I came away from this class feeling like I learned absolutely nothing.

Oh has a unique talent for ignoring student feelings and never bothers with such trivial matters as seeing things from their perspective. Truly, a 'remarkable' choice for anyone seeking an 'unforgettable' learning experience. Highly 'recommended' for those who appreciate the finer nuances of educational indifference.

This man eats boring pills for breakfast, lunch, and dinner.

Prof.Oh is approachable and organized. Grade is determined by 2 exams (25% and 35%), and 40% hw. One downside is his complicated lectures; the material is not the most difficult if you read the textbook but Prof.Oh's lectures make them seem more complex. The exams were conceptual and much easier than the lectures. The class uses R language.

I had Oh for 134 - he's been a good prof. Very accessible through Nectir if you need help on HW. I will say his HWs are VERY long and were extremely difficult as I'm pretty new to Python, but you get 2 weeks to do them and can work with others. Exams are easy and the final is a simple project, meaning I've done much more learning than cramming.

He's a great professor. I didn't have him for PSTAT 131, but I will say that 131 is notoriously difficult since it's streamlined course by the department. Oh has been exceptional in 134 in terms of explaining material and concepts. Don't expect and easy A but expect a fair course. Keep up with the material and you'll be fine.

Professor Oh is really available whenever you have any questions. His lectures are more about concepts, and the quizzes are based on that. He doesn't talk about coding in lectures but the homework is in python. Therefore, you may need to learn by yourself how to deal with it. However, he will give hints and documentations in the prompt.

Great material. Great HW. However, Professor Oh if you are reading this, please be a bit more specific on what will be on the midterm. You made it seem like it was Heavy Coding exam, when it was mostly 50% theory, and the rest coding. I screwed up my midterm because of this. If I would have known it was heavy theory, I would have gotten an A+. (
