MATH4A . 6 Months Ago

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.

MATH4A . 6 Months Ago

Lectures weren't mandatory, there were no midterms or a final, the class was only graded by weekly homework and five online/asynchronous tests, and the lowest score is dropped. Labutin is the goat.

MATH4A . 7 Months Ago

His lectures are very theoretical and quite confusing. However, there are 5 online midterms and no final, and the homework is all webwork, so it's easy to get an A. The TA ended up being really helpful and all the section worksheets were just like the midterms. The only reason I understood the content is because I took linear algebra in hs.

MATH4A . 8 Months Ago

5 online tests and homework which wasn't bad. However Prof was a terrible lecturer and you basically have to self-study using youtube, CLAS, or hope for a good TA.

MATH4A . 10 Months Ago

Just 5 online tests, and homeworks which are not that bad. But the class is poorly taught, mainly depends on the student to self study with youtube, CLAS, finding the textbook online, or hope they have a good TA.
