Can you elaborate on how you went about studying the concepts so that you can attempt any question in JEE?

Firstly, we have to be strong in the basics and after that go to attempt the questions. While attempting a question, if you feel like that you don't know something or if you are doing the question right then you need to go through the concepts and revise again.

In the starting of preparation, just study the concepts and then attempt questions related to that concept.
