Hello Student, 

I am sorry to say but as per pervious year opening and closing ranks of JoSAA it's not possible for with your rank to join any NIT or IIITs.

As EWS is new to all, so predictions might go wrong. But I suggest you not to depend on EWS completely and search for other options too.

One thing that you can do is try participating in CSAB special round if you want NIT only.

Feel free to ask any doubts.
Thanks.
