I have been tutoring since last 4 years now. Initially, i started with home tutoring but later on i started to take classes in the coaching institutes as well. I have a good experience of dealing with the student's doubts and confusions. Over the past few years of my teaching experience, I have learnt to explain a concept in a simple and elegant manner and also to clear each and every doubt of student no matter how silly or complex it is. I can assure students that I can make them understand the concepts I teach.
