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
