This is a profile of Jitendra sir, who is teaching mathematics to different levels of students for more than 26 years. I use the local Hindi language for better understanding and easy English for notes. Nowadays, I teach and guide undergraduate students having mathematics as their core paper. In addition to this, I teach and help students to clear various competitive exams like PGT, CSIR NET-JRF, M.Sc ENTRANCE, IIT-JAM, etc.
