Best prof ever.

He may come off as stern in lecture and it can be hard to understand him with his accent sometimes, but he is actually insanely friendly and dedicated to making sure you understand the material. Take this class with him. His homework is not too demanding, and it prepares you well for exams. Additionally, you need to at least read his lecture notes if not attending lecture because many of his exam questions are directly covered there. Exams are straightforward and don't test you on anything not covered. Very doable if you've studied. Not exactly easy, but I think that's just the material of the class, too.

GO TO OFFICE HOURS. He's so helpful and friendly there, really makes the class a blast.

I like Oleg. He has his faults - he's prone to rambling during lectures, sometimes goes over stuff that is poorly covered with the textbook, and has this strange resentment with north campus-like majors - but he's a good math professor.

He goes into great detail regarding topics and theorems, and often gives real world examples for those who are less theoretically inclined. Each of lectures has at least one example per topic, sometimes more, and he really delights in answering questions, so ask as many as you need. Lastly, and perhaps the only one I have seen do it so far, he holds office hours during all times of the week, for those who are local and those who are overseas, so that all of his students can make office hours if need be.

Testing wise, he will, and I mean this, he will absolutely tell you what will be on the exam. He will tell you, like, that you will have to parameterize a torus and then will be willing to do it in office hours, if you ask him a week later or something.

nice person, below average teacher for me

Great guy, terrible teacher.

Math 32B with Oleg happened to be one of my favorite classes I've taken at ucla (it might be because I only took this class over summer session so more time to study but still a great course).
I had him for 2 hour lectures, and he would give us the break and most of the lectures were engaging and interesting. The material is really hard so Oleg would spend a lot more time covering the more difficult parts.

Really, in order to keep up, read the textbook before class. you'll understand what's going and then learn more in class why things are happening. Takes up a good amount of time but it'd probably be harder trying to memorize everything instead of actually understanding the material.

His office hours are really helpful, especially if you have a homework question or a question with something from lecture.

He cracks the lamest Dad jokes, but theyre so bad theyre funny and it lightens up the mood during class.

The other reviews say his accent is bad, but honestly it's a Russian accent that isn't even too profound: you can understand what he's saying.

Yeah, most of the material was learned with the book, but the professor helped me understand even more on what's going on.

I was skeptical of taking him for 32B because of the previous reviews, but I figured since they're old, he might have new methods of teaching. Though he had a few interesting blurbs about math history, I realized that all the reviews had been true. Lectures were rather erratic - one day he questioned whether we knew how to add vectors, and another day, he told us that we were all electrical engineers and should be able to understand this when the second midterm scores came out low. He tended to be behind on lectures and had to do a three hour review session (which was really a three hour lecture). Final seemed to have little to none connection to what was discussed. Would not recommend.

His lectures are very straight-forward and you know exactly what you are covering. The best way to study for his tests is to go over the examples and derivations from from class and the homework. He will use the same problems or similar from what you have already covered. He does not try to trick you, he just wants to make sure you understand the information. During his lectures, if something does not click he will happily go over it again for you. He is very nice and approachable.
