I have 6 years of rich teaching experience in subjects like Mathematics, Accounting, and Entrance Exams preparation. With my experience, I am able to quickly adapt to the student's level of understanding and make the best use of his time.
I focus on teaching concepts along with the applications and what separates me is the connection I create with my students. I am well qualified for working on complex problems and reaching out to the solutions in minimal time. I was also awarded 'The Best Tutor Award' for 2 consecutive years in my previous job.
Hoping to get to work on some really interesting problems here.
