@ Debalina, For gud preparation, its not the no of buks that matter, but its the quality of buks and quality of your study...

The buks you have mentioned are sufficient if you complete them and understand them and are able to solve such types of Qs by yourself. And, if you complete these, then go for anotherones.

For Physics, U can also have HC verma. I would prefer HC verma over ur book. If you can complete HC verma , nothing better than that.Best of luck...:)
