Hi,

First of all treat NCERT as your bible because it has all the basics which you need to know. You should be clear with your basics. For biology NCERT is good, for better and deeper knowledge you can refer trueman.

For chemistry, I would suggest modern ABC volume 1and 2 for both class 11 and 12 along with NCERT.

For physics HC verman and modern abc along with NCERT.
