So, it's bad enough that chemistry itself is a terrible subject, but this guy can simply NOT teach. His accnent is waaaaay too thick to understand he pronounces his z's like j's. So he'll say "jero" instead of "zero". The guy's smart and everything but he can't teach. :l Don't take this class with him. I'm probably gonna fail, honestly.

I had kumar last year for my second semester chem couse. What I liked the most was individual attention and help. I had done some reading before and it was easy A for me with good lectures and how the course was organized. Prof. Kumar has deep knowledge of the subject matter. The only comment I have is some of the lab grades came late.

Although I love how Professor Kumar was able to explain things in an easier way, I found myself drowning in the amount of homework, quizzes, and materials he posted. He posts hour long lecture videos for a quiz grade (multiple per week) and 30-50 question HWs a lot, and I was taking other difficult classes, so his class was very exhausting for me

Possibly the worst professor in all my college years , can barely understand him and is constantly judging and downplaying your every move .
