Hey anupam.

See the percentile u have score dis not enough for to qualify for giving the JEE ADVANCED exam as well as it is not sufficient for u to bag a seat in the good colleges like NITs , IIIT sand GFTIs for pursuing ur higher studies in the field of ur  interest. U should be going for state colleges and private institutions for ur btech career.

Hope h got my point. Ask if. Any query.

Good luck
