My Experience: I have been teaching students for last 7 years and the biggest achievement a teacher can have is the achievement of his student. During these 7 years, i have had students who are toppers in their field of study.
My USP: Students love to attend my lectures because for me physics is the first step of engineering and being a mechanical engineer from one of the top colleges and add on industry experience helps me to relate simple topics of physics with their practical use.
My methodology: My approach towards teaching physics is based on question solving. Because unlike theoretical subjects, only a simple concept has to be taught properly and the student can build on that concept to solve difficult questions if he is step wise questions to reach that level.
