My dream is to make students independent of Coaching and save their time and money. My small and humble contribution to inculcate analytics and scientific mindset amongst youths. Please note, I have not monetized. Youtube still gives advertisements. If any student has financial issue, I am willing to teach him free off line at Dehradun. No other classes.
