Hi, I want you to know that BITSAT is a dream college for engineering. And it offers direct admissions only to the toppers of board. You cannot be admitted just because of your 90%, you need to clear the exam conducted by BITSAT. Unfortunately, you missed the chance this year but you should try in 2018.
Good Luck

BITS, Hyderabad or any other BITS campus is much better than VIT. I am not saying this because I am from BITS, but BITS Pilani has much more value as a private college than VIT. So, if you have a good BITSAT score and you are getting Computer Science branch in BITS, Hyderabad, don't hesitate to opt for the same.

Pilani is the main campus of Birla Institute of Technology. Pilani would be right choice for you. Pilani campuses have highest placement record.

XIMB-RM is definitely better and more known and reputed.
