Hello Arun,

There are absolutely NO donation seats at any BITS Pilani Campus. 

If anything, there are 10-15 BET seats reserved solely for the top-performing children of teachers from the Birla School in Pilani, and the catch is that they cannot get an Engineering Degree, no matter how well they perform.

So still the answer is - NO donation seats. You don't buy your way into BITS, mate. You can try next year if you really wish to get admission in BITS.

Good luck!
