Dear reader your percentage is quite good but according to my personal suggestion you should first make yourself very clear about preferring college over branch or branch over college. i would suggest if you are genuinly interested in CS or IT then be ready to compromise a bit in college allotment. just be sure that you want either CS or IT.

So i would suggest go for top IIIT's , IIT'S, and also NIT's as per your eligibility but make sure you be very strictly branch oriented. fill only your choice of branch and if you excel in it in any of the college among that list then your knowledge will take you places.
