Hello Applicant,

In my opinion, that would be enough.

In BITSAT questions are not tough they are of a basic level so if your basics are good then try to learn important formula of important chapters and revise again and again.

You need to put yourself through a taxing mock routine for practicing time management and enhance your solving speed.

Also, I suggest you consult Arihant package as the book has questions which are exactly at par with the level of the examination. The book is well revised and contains most questions which are repeatedly asked in the exam.

Good luck!
