Hi vishal ,
Congratulation for such a wonderful score.
Considering your rank there is very less chance for you to get admission into top 3 nits (i.e nit trichy ,
nit warangal,nit suratkal ). With computer science branch.

But still for electronic and communication branch you can apply in any nits even top 3 nits.

In rest nits you can even option for computer science branch with your jee rank .

Hope it helps !!!
