All the very best and good luck.

I am afraid to tell you that this might not be sufficient to get a seat in NIT. But, you can get other government colleges as well as good private colleges at this score. However, wait for official results declaration. Only then picture will become clear.
Also note that you will definitely qualify for JEE advanced at this score. Try to score good enough in that so that you may get a seat in IIT.
All the best.

110 marks with OBC category is not enough to get any NIT through mains but if you are able to qualify the cutoff and appear for advanced do try your very best to score as much as possible in order to get the maximum output and the best college possible.
Obviously you could consider taking a break I drop year and I'm preparing hard for all the other exams that you would be considering.

110 is not that sufficient yet you may have a silver lining because of your category. I would suggest you to prepare hard for advance or take a years drop and appear next year for mains, it getting IIT and nit is your only dream.
