Yes u got a good rank , congratulations ....

With ur rank u get CSE in all nits except

1) nit Trichy
2)nit Rourkela
3)nit Warangal
4)nit surathkal
5)nit Allahabad
6)nit Calicut

So if u wait till round 7 u can expect above result ...

And if u participate in spot rounds then u can expect nit Calicut or Allahabad ...
But be careful that u have choosen a college before round 7 to be on safe side as getting seat in spot rounds is no so easy and can also miss it
