MATH4A . 8 Years Ago

One of the worst lecturers I've ever had. Hard to follow even when I already knew the material. Expect to self-study most of the course. On the other hand, he curves the tests a lot -- average score on the first midterm was 105%.

His lectures could often be confusing when they didn't have to be because he explained all concepts in convoluted variable expressions/hardly ever used examples with real numbers to clear things up. That being said, this class was very easy to get an A in: extra credit and take home midterms with a fair final; go to CLAS if you need help.

Thick but decipherable accent. He obviously knows a lot about linear algebra, and can prove the concepts on the spot for you, but he moves fast between slides and tends to not be very concise or planned in his lectures. If you do the homework and learn from the book you'll be fine. I passed with more than 100%, but I'm already a math major. Sry :/

Very thick accent and makes it difficult to understand what is going on during the lecture because he skips and jumps from slide to slide. His lectures are not that helpful. I would really reccomend taking clas and studying from the book and doing the homework. Tests are very similair to practice. Overall pretty easy class.

It's so hard to understand what he's saying because of his accent. But the lecture notes are pretty clearly and the tests are easy. I recommend to take his class, if you can accommodate his accent, you will find it's very easy to understand the course content. BTW, textbooks and lecture notes are really helpful. You should learn sth by yourself.

His accent is thick and extremely hard to understand. He doesn't explain anything he teaches, just reads off his presentation. I quit going to lecture about a week after the midterm because it was bogus. On the bright side, you can cram the entire quarter's worth of material into a cheat sheet for the final. Taught myself all the material I missed.

The final is tomorrow, and we still haven't received our grades for the second midterm. Thick accent and lectures are incredibly dull. Honestly not even worth going to lecture.

"Is aluminum an element?" Also, midterms grades will be posted two days before the final. Silver lining is the fact that you're allowed a one page front-back cheat sheet for all exams. Cram the entire quarter's worth of material in that sheet and you're golden. No curve.

Labutin, formally known as Labooty, is a Russian exchange student who knows math yet can't communicate it to his student. Common spoken words are "umm" and "obviously". No Labutin - this is not obvious when you make it seem like rocket science. Tests are very basic, which is good because you will not learn a thing without Kahn Academy and CLAS.

He is near impossible to understand and his lectures don't cover anything on the homework or on the midterms.

His lecturing on complex analysis was ok but in the end he turned the class into a PDE class.

If u wanna learn something, do not take his class!!! He makes the abstract algebra more abstract. Literally talking to himself in the lectures. He finished a whole topology book in a moth. Avoid him at all cost!!!

Just live in his OH's and everything will be alright.

Didn't bother watching his lectures, just read the textbook and his powerpoints. Some hw problems are hard and not at all what he taught but he drops some hws. What really matters is knowing how to do problems he bases his tests off of. They are exactly the same. If you can do those you will get an A on all tests. No cumulative final, just 5 exams

it's legitimately impressive how little feedback a professor is willing to give. it's the last week of the quarter, he just assigned three new homeworks due during finals week, meanwhile he has seven outstanding assignments to grade. i'm in awe.

began the first day of class by saying this isnt going to be a complex analysis class, its going to be riemann in geometry with the complex you need learned on the fly/on your own. this is supposed to be an intro complex analysis class. instead he consistently used material from courses that are not prerequisite or necessary if taught properly.

Homework is extremely hard. Doesnt use textbook for reference. He has his own system to teach the class. Class materials are almost irrelevant to homework.

I don't think the accent is a problem. His handwritings are sometimes messy, but you can ask him to clarify. His homework is harder than other math 8 classes. We don't have final in final week, but we have 3 exams and the last one is during the dead week. It really helps to release your pressure and all the things tested are very fair.

Worst professor ever! CAN'T UNDERSTAND HIS LECTURE !!! Even though a lot of people say this exams are easy, that may not be relevant in his upper division class. I got 89% course total, and I ended up getting an B+.

WORST prof I've ever had at UCSB. Lectures are impossible to understand and you basically have to teach yourself everything. Midterms weren't too hard but the final was horrible! If you can avoid taking math with him, I highly recommend!!

A little difficult to understand, I'll admit, and you have to spend some time outside of class to learn the material but he is very willing to help his students pass. He assigns homework once a week (about 15-20 questions). His study guides are EXACTLY like his tests, which are really easy, AND he offers extra credit. (the class avg was an A!!)
