Hey Abhishek.

See the score u have scored is just on the verge of the cut off score for the selection in the field of ur interest in IIIT BANGALORE. U might get seat in the college in the third round but that too can't be said on surity.

U can apply for other state colleges and private institutions for ur admission. U can also check some of the NITs for ur higher studies.

I m providing u a link of college predictor. Hope it will help u.

Ask if any query. Good luck
