Hi aspirant

There are several books from which you can prepare .First of all i would say to finish the NCERT examples (very important) and then after exercise problems.You can practice sample papers from Arihant publications .They are best.Not only for physics Arihant previous year papers are best for all subjects.Once your are done with both i.e NCERT + ARIHANT you will be in a position to solve almost every questions.You can buy these books from amazone/flipkart or from bookshop in your market.

Apart from solving make your own notes and formula chart and before solving any mock paper just revise your notes .This will be really helpful for boards preparations.

Good luck

Hello sir

Actually first you should follow the syallbus by the particular board,  according to my suggestion the Physics paper of 12th board  contains the theory concepts and as well as problems also so please study both theory and problems

All the best
