No ,try other state nit and any other university there is only 90% chance. Because now a days you know how the situation is. Many were trying to get  nit and iit that's based on your luck ,so try to be strong and understand yourself keep going on you may try other mains university or colleges upon your score .

But I say here is there is 90% chance to get for NIT for you

Hi,

The JEE main is considered as one of the main entrance  exam because through this you get admissions in NIT, IIIT and many more best colleges in India. Seeing at your percentile i can say you have surely done a good job as your percentile is quite impressive and talking about admission in IIIT Hyderabad it is one of the finest IIIT in India and its a good option for higher education, so you definitely make try for admission as you have one more advantage of OBC category so you can surely get this college and also it depends on your desired field in which you are interested to go.

Thank you..
