If you belong to general category than it will be very difficult to get admission in a NIT or IIIT. However, if you are from SC or ST category than you have a chanve of getting into a NIT or IIIT but still branch can be an issue. Meanwhile, you can also try for private colleges and other state level government colleges and universities where you might get a good branch. All the best. 

You may not get any NIT.

Try for some state colleges or if you have appeared for VITEEE, MUOET or SRMJEE then try for them.

HOPE FOR THE BEST

ALL THE BEST KRISH VERMA
