Hello candidate,

The BITSAT examination is an online examination and its exactl questions are very rarely published in any books because these questions are never disclosed by the examination agency.

But, here are some of the books which I am sure would definitely help you in your preparation-

Concepts of Physics by H.C. Verma +Vol 1 and Vol 2)

Arihant Physics by D. C. Pandey.

Organic chemistry by Himanshu Sharma

Integral and Non Integral Calculus by Arihant Publications

Good Luck!!
