BITSAT

Hello Piyush,
You have stated that you have completed class 12th in 2015. Those who have completed class 12th in 2015 or earlier are not eligible.

Hello Hasnain,
To appear for different entrance exam can be quite taxing for a student. The solution is to have a single All India test on the lines of NEET for medical admission. But, for this pressure needs to be exerted on government to take some action.
It will enable you to enhance your ability to think logically and fast. There is actually very minor difference in syllabus for class 12th by different boards across country. So, do not get bothered.

The candidate appearing for class 12th examination in 2017 or passed class 12th examination in 2016 are eligible for BITSAT 2017. If a student has taken more than one attempt in class 12th or its equivalent, then his latest performance is considered, provided this attempt has been for the full component of subjects.

Revise the topics you have read and leave few topics which are hard for you.

Hi,
If you are good at your academics from last 3-4 years you can crack BITSAT. Now, try to do many number of previous years' question papers and learn the concept from those. This might help you a lot as it has very short span to study.
All the best.
