Hello student ,

The best book for the boards examination of physics in Bihar is NCERT Physics of class 12 , the questions in boards examination are from NCERT books and you do not need any other book if you have good enough knowledge about NCERTS , adding Previous years question paper and sample papers to your preparation you can easily get 90+ marks .

If you still need a book you should buy Pradeep 's physics book , it is a very good book with easily understandable language and tons of questions for practice .

Hope this helps.

Hello Aspirant,

Hope you are doing great. For board exams of 12th you can refer to the books of the "Concept of physics" by H.C. Verma  and you can also refer to the book of Understanding physics the basic concept involved by D.C.pandey and the problems of General physics by I.E.Irodov. You can refer to the books for basic understanding and to practice problems

All the best
