I had bad experience with him. His lecture is not helpful at all, and he also doesn't care about teaching or students' wellbeing at all - if you're learning or not. And he does not show up office hour. And even if he's there, he's not even helping. Avoid him if you can
Lectures in a thick accent and mumbles. He goes into long theoretical derivations rather than doing examples. When he does do example problems, he'll skip half the steps and not explain what he's doing. Be prepared to learn everything outside of class if you want to do well. 60% of the grade is the final.
He has an accent and is a little quiet, so it's difficult to understand him at times. He's nice and caring if you go up to ask for help, but a lot of self-studying is needed to do well on the final.
This class was pretty hard, online midterm was easy, final was difficult. If you do all homework, go to lectures, and don't fall behind, you will get an A.
The homework and two online midterms were easy to get 100 on, but I had to teach myself basically everything. The final was in person and much harder than the midterms. Many people were cheating but for those that completed the test in good faith, the grading was very nice.
Two online midterms thats easy to get 100%. Final is very bad, which is basically a row reduction test involving impossible fractions (literally heard people sighing when taking it). Professor is nice but has heavy accent. Questionable exam proctoring with people literally cheating which results in the class being unfair and having minimal curve.
