Hello aspirant,

In order to crack examination like JEE Main it is very important that you have understood the concepts well and have knowhow of the basics first. You have understood the concepts, So that is fine.

Now , solving a large number of books is neither important nor much beneficial as well. It consumes your time. Rather you can take one book and do it multiple times. In your case you have solved on questions asked in JEE Main. This is finer as JEE questions are compilation of numerous book questions. Solving less questions from JEE main is equivalent to solving several questions from refrence books. So be calm, confident and have patience. If you have solved it thoroughly you will definitely score better.

All the best.
