Hi Shravan

I am going to suggest some books which have great importance in exam preparation.

1. Concepts of physics vol.1&2 : HC Verma

2. Fundamentals of Physics by Hallisay, Resnick and walker

3.problems in general physics by I.E Irodov

4. IIT JEE Physics by D.C Pandey

Also, practice end number of previous year question papers and mock tests make your basics strong and keep revising all the concepts properly.

All The Best!!
