Hello Rahul, you might get a seat in the special round if there are vacant seats left in the NITs after all the rounds of counseling. You have not mentioned your category and home state here. If you have Tripura, Meghalaya, Goa as your home state, you have a very good chance of getting a seat because these NITs have high cutoffs.

Dear Aspirant 

First of all Congratulating you on your nice performance and I would like to tell you that based on your rank (since you have not reveal your category) I think you will get any government college through jee mains but if you could not get any seat then I would suggest you to must participate in spot round counselling conducted at the end of the normal round. 

Good luck for your future :) 

Feel free to ask if you have any further queries.
