BY heart i am saying Teaching is my passion , it is a source of enjoy for me . during my IIT JEE preparation i always use to teach my friends solving their doubts like a brother (so they are also IITians today), toady in IIT itself my friends use to learn by me during examinations. I teached in zenith edup during my last summers,Diwali vacations and really really they and me enjoyed a lot . There was one question on projectile from a running train to another opposite direction running train in which the final ans was the projectile will crash each other in 2.7 secs ... initially some of them don't understand then i took a example by making two students sat on each projectile and tried to give them feel , really the moment was really enjoyable after the question finishes because they solve the just next similar question .
2nd memorable situation was when we are discussing "Discovery of electron" by relating with a story and whole class was listening so carefully , i was confused the are listening the topic or goes deep in story but after the end of class they explained me well .
So now let's come to the teaching methodology now-
1. we will always start a topic by correlating it with our daily routines so that you can easily understand.
2. After every topics we will take 3-4 popular examples and then a task.
3. you all will feel so free to stop me anywhere and ask your doubts.
4. Then we will do question discussion of task at the end or may be at beginning.
ALL THE BEST (Keep rockin)
