Hey Kashif.

See any entrance exam cannot tell that u are eligible for some other exam or not. It may happen that one have scored less marks in mains due to some reason but topped or scored good marks in any other exams like WBJEE , COMEDK , BITSAT for pursuing his/her career from the reputed colleges in the field of their interest under btech course.

Hope u got ur point. Ask if any query.

Good luck
