I'll answer honestly... This is one of the best videos I've come across on youtube. No irrelevant talk just straight to the point teaching and that too with a very good concept clarity method in a language understood by most. Sir hats off to you!!! No promotion nothing just teaching students for their own benefit. You've earned mine and a lot of other student's respect!
