My name is Utkarsh Gupta(AIR 17 JEE Advanced 2016). I am currently studying CSE at IIT Bombay. I would like to thank CKP Sir for his valuable insights and spending his time with me in problem solving sessions in which problems were beyond JEE level but sir solved them easily and showed me how tough problems can be solved through systematic application of concepts. Sir has a very strong grasp on the subject and very crystal clear concepts and strong problem solving skills. I benefited immensely from my sessions with him which helped me in my doubts and strengthened my concepts and problem solving skills. In my opinion Sir is one of the best mentors one can ask for for IIT JEE physics and I would like recommend him to any hardworking student looking out for an equally resonating and hardworking mentor. I would like to thank sir once again for his guidance and support in my journey to JEE Advanced and physics olympiads.
