Well my Physics was my weakest point during my preparation and it cost me an extra drop year. Due to Rahul sir it became one of my biggest strength during my second drop. His pattern of teaching is based on improving of concepts and then doing questions based on that concept. The result of which is that I am sitting in one of the best medical college of the country now. If you are looking for a good physics teacher who can deliver results, Rahul sir must be your choice.
