The material is valuable because it's clear and concise, but dr. Raj has an annoying and hard to understand accent and weird manner of teaching.
I really like Dr. Raj lectures but, why these videos don't have subtitles?
It would be nice if the material was presented in a less intense manner. It feels more like he is prepping football players for a big game. It is very distracting. Perhaps, if the lecture didn't feel so choppy it would be more enjoyable.
