Hello,
NCERT At Your Finger Tips (Physics) is an objective type book that helps in preparation for JEE Main/NEET.
Although for a student who is good at NCERT already, this might help him/her to practice questions and the same can be applied in Boards also, if you want a book exclusively for Boards, then this is NOT recommended.
For preparation for Boards of class 12, you need a book with previous year questions (with answers given along with the marking scheme) and theory description also.
You can consider Arihant Sample papers, Arihant All In One and Arihant Previous Question Papers.
Hope this helps.
Thanks.
