Again i would say no matter how weak or strong are you in studies if you really really want to improve then you have the best teacher as a gem but the only condition is consistency and hardwork and be loyal to the teacher.

Because the way he teaches is commendable and easy to grasp . His techniques are awesome.

I know Saurabh from our college days. He has been teaching as part-timer since college days. He was a dedicated teacher and mentor.
Once, we had a practical exam which extended by an hour and he had scheduled a class for a student. He informed students parents that he will be late by an hour or two and he actually went there to teach that students after 5-6 hours of practical.

He is a man of his word.
