Hello Nikhil,
To score high marks in BITSAT, you need to have speed with precision. To crack it, you must keep these things in your mind, have a good grip over NCERT textbooks along with a good practice of previous years paper, solve 1 -2 test paper every day, and have a proper time management, question question-solving time, these will surely help you in getting good marks.
All the best.

For the first year, I'm not sure about the fee concession. Maybe your BITSAT score can be considered. If you are a board topper, then you will a get full fee waiver.
But from the next semester onwards, if your CGPA is above 9 or 9.5, then you will get mess fee and hostel fee waiver. But this depends on your CGPA and the administration.
If you get the above CGPA, there is an option to change your course also.
All the best.

You can get the fee structure on the official website. Yes, there is fee concession on the basis of class 12th score.

Hi Rajat,
There are only two ways for getting into BITS-Pilani, one is you need to score 300+ in BITSAT, or you need to get the highest marks in your boards from your state.
