In my success Upendra Sir has played crucial rule, not only in concept learning but also in motivating me throughout the journey. In the starting my concepts were very weak. I never thought of getting into IIT but all thanks to Upendra Sir, a gem. He taught me everything from basics to concept building and developing confidence in me. He never denied to take doubts in class as well as outside of class. He is always dedicated towards his students. Instead of mugging up, he taught how to Learn. It was a great learning experience from hime.
