You have not mention which stream to you belong as the book of Arihant Publication are the best books for the boards of class 12 and previous year question papers are the the best for the preparation of the 12 board

otherwise Self prepared notes are the best so try to make your own notes in your own words which will help you in the boards for securing good marks and good percentage.

If you can't find the books at your place just please mention your area or state , with your stream so that I could provide you a detailed information .
