Dear Student,

Firstly, you don't need to take much tension. If you want to crack your exam you should be dedicated and self motivated. 

You can plan your study. Make your proper time-table according to your strength and weakness. Give importance to the topics which carries more weightage in the exam. 

In order to score good marks in BITSAT your concepts should be clear. NCERT and Arihant are the recommended study material. 

You can refer previous year papers to understand the exam pattern and to know level of the questions and solve as many as mock test series for your practice and to increase your speed and efficiency.

If you are well prepared for JEE Main exam you can crack BITSAT exam easily.

All the Best!!
