Hey there

Your question is incomplete i guess. But still if you want to know about books for class 12 them for maths you can refer rs Aggrawal or r d Sharma. For physics Pradeep's physics and hc verma. For chemistry NCERT is good and enough but still you can read Pradeep's chemistry for boards.

Good luck
