I am in 12 class and i want to know that which book is best for physics And chemistry for the preparation of jee mains..

Hello Priya

For Physics- you should go through NCERT once.

For basic concepts understanding - refer HC Verma
Other books which are mostly referred for question solving and topic wise question practice are - DC pandey, I.E. Irodov.

Try to keep your concepts clear and then you can solve any kind of question. Just refer the above mentioned books and do not run after so many references.. as it'll create confusion and time wastage.

For Chemistry - refer Arihant Practice book, J.D. Lee, R.C. Mukherjee.
Make sure you go through the NCERT first.

Hope this helps.!
Practice more number of questions as much possible.  then only you'll get idea of the question-level-pattern + the applications of the formulae and the logic to be applied where and when.

So prepare well and study smart.!
All the Bestt.!!!
