Hello Arvind,

According to your AIR, you can expect a very few NITs but I am sorry to say but IIIT Bhubaneshwar is not possible. The cutoff for IIIT Bhubaneshwar is around 40000 max.

And since EWS is being implemented from this year itself, it is not possible to predict the cutoff for EWS category. 

I am enclosing a list of possible NITs you may get with your AIR - 

• NIT Srinagar - Material and Metallurgical Engg.
• NIT Mizoram - Mechanical Engg.
• NIT Sikkim - Civil Engg.
• NIT Meghalaya - Civil Engg.
• NIT Agartala - Production Engg.

You can only expect to get a few NITs that too the ones of N E India which aren't good. 

I would suggest either you apply to other private colleges or take a year drop and repeat for next year. 

Best of Luck!
