Hi Candidate,
The Oswal Publication Physics NCERT Book is a very good book if you are preparing for your Board Examinations, as it has a variety of Questions and examples covering almost all aspects of BOARD Examinations.
If you have practised the book well and have revised it properly, you can score around 90% marks as the pattern of Questions asked in Boards are very much related to those given in Book.
Hope that this answer helps you.
