Hii

Congratulations on your success. You have a decent score and stand a chance to get admission into NIT.
But since the cutoffs have not yet been released so nothing can be predicted.
If we see the previous year trends, then yes you have a great chance to get ECE at NIT. But as we know cutoffs keep on varying year after year, branch can not be predicted.
You need to wait till april for the official cutoffs to release.

Hope this helps
Thanks!
