I have more than 7 years of experience in teaching physics, mathematics and python programming to more than 600 students including both online and offline tutoring.
I follow the following 7 step fundamental approach towards tutoring.
1. Curiosity, scope, enlightenment of the topic in hand.
2. Problem Definitions and elaboration.
3. Requisite mathematics, analytical abilities and quantitative
aptitude.
4. Preparing Algorithms for problem statement.
5. Concepts with analogies and building algorithm.
6. Introspection and improvising.
7. Daily class wise Cheat sheets(its not cheating) for consolidation.
