Hello,

Please mention the name of college for which you are asking.

For NITs/IIITs/IITs you need to score atleast an aggregate marks of 75% in class 12th board exams and for BITs you need to score 75% aggregate marks in pcm in class 12th board exams.For VIT and SRM UNIVERSITY you need to score an aggregate marks of 60%in pcm in class 12th board exams.

For other private colleges 60% marks is quite enough.

Good luck.

For nits iits 75% is necessary but for normal colleges every college have different criteria.
