Hi,

I am assuming that you are planning to prepare for engineering program. BITSAT like any other engineering entrance exam has the same questions from different subjects like chemistry, physics and mathematics. Here under I am suggesting some books that you can refer for your preparation for the same. Along with that you can enroll yourself in different test series by various coaching institutes and can practice exam papers

Books

1. HC Verma for physics

2. Pradeep and Universal self scorer for Chemistry

3. Any decent practice book for mathematics. Arihant publication has its own practice book and you can refer that for practice.

I hope this helps.

All the best.
