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.

Labutin is fine, neither excellent nor bad at teaching. His class is not very hard. And he has accent but is not hard to understand. Some said he grades easy, but this is not the case for 118(seems he doesn't curve), e.g. 91.5 is A-.

Labutin is a great professor but the grading scheme was lackluster with no curve. This is a hard class but not impossible, and if you do the homework and the reading, you should be well equipped for exams. 3 exams, open note inlcuding take home final. It's a hard class but a very awesome, interesting, and mindbending one, so don't get discouraged.

Rushes through topics and homework is SO LONG. Assigns one very long written homework and one webwork assignment every week. webwork is limited to 3 tries instead of unlimited tries like usual. 2 midterms. However the final was online and the course ended in week 9 which was nice so you can focus on other finals.

hard class and fast lectures but he teaches it very well. homework takes a while, though exams are open textbook.

Labutin just reads off of lecture slides so I stopped attending class. All tests were online and made the class much easier. Although he's a terrible prof, the class was super easy.
