MATH4A . 2 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.

MATH4A . 2 Months Ago

Class was very easy, 5 online, at home tests instead of a midterm/final. Not good at lecturing, talks too much about theory and not enough about how to actually solve problems, but my TA understood that and was how I did all of my learning for this class.

Professor Labutin's lectures make no sense. Going to lecture just made me more confused. There are no midterms or final, just quizzes every other week that are take home, open note. Having a good TA and attending CLAS made the class manageable.

MATH4A . 2 Months Ago

Labutin's lectures are usually confusing and hard to keep up with. That being said, this class is a free A, all tests are online and at-home, open note.

MATH4A . 2 Months Ago

Professor Labutin was a challenge, in that -though he seems to be a very caring and available teacher- he did very little explanation in his lectures. It was hard to follow what was being talked about, and more times than not I ended up having to teach myself. If you have him, make use of TAs, videos on youtube, and study groups for understanding.

Prof. Labutin is nearly unintelligible in lectures and very disorganized. In a lecture of about 500 students, eventually less than 100 showed up. Despite this, the exams were super easy and the class average was in the high 90s. Homework is tedious but manageable.
