Is it necessary for a student to go in IIT coaching institutes for cracking IIT entrance exams?

Dear Devanshu, Coaching institutes provide tricks to solve maximum right answers in minimum time. It creates an environment around you to grasp knowledge and to learn. If you are able to do so then you don't need to join any institutes.

no ! It's not true . Just work hard.
