coaching

I took online coaching from Educomp for mafa, CA Rajiv Singh was the teacher.  I am fully satisfied and in my opinion he was one of the best there.

but my friends say he is not up to the mark is he really good

Now this is a subjective decision.  I can comment only if you can tell me the drawbacks which you friends have pointed out in his teaching. (Reply only through a PM, not here)
