Dear aspirant,

You need to figure out on your own for your preparation strategy because for every individual the preparation mode is very different. I have cracked jee mains and my preparation was totally different from other jee aspirants. I did not refer many books like for example in chemistry op Tandon ,ms chauhan, p. Bahadur. It's important for you to get the concepts right in your brain.

I never liked HC Verma in physics so I referred dc Pandey and pvq for all the subjects and the handbooks of Allen coaching . It was enough for me.

Dear aspirant!

It will not be enough for JEE advanced ,you should also refer other books for scoring good marks like for chemistry prefer organic chemistry by O.P.Tandon , inorganic chemistry by O.P.Tandon. , DC Pandey 's physics book , and for maths prefer advanced problem in mathematics of R.D.Sharma.  Also practice pyq of all subjects again and again.

All the best.
