Hi, Rakesh. 

The minimum rank required to get into the NIT for a student of your category is less than 1000.

As you got the rank less than 1000, you have quite a good chance to get into the NIT.

You can try for the state quota of your state, where you'll have the much better chance to get into as they'll have the reservation for the state quota.

Hi Rakesh,

As per rank and category, you will definitely get a seat in any one of the NITs depending upon your home state. You are eligible for all the branches.

Thank you and best of luck.
