I am a student at IIT Kanpur , which is one of the prestigious colleges in INDIA.
Cleared JEE Advance in 2017.I am a flexible teacher because I understand that all students learn in different ways and at different paces. When teaching, I make sure that every student has a grasp of the subject before moving on.
I will help student to get the basic understanding clear. I believe friendly behavior with student can help both the student and the teacher.
I love science and my students do the same.
