Hello aspirant,

Getting into IIIT Hyderabad doesn't have any reservation and is purely  merit based,as per previous year's cut-off it is really difficult for you to get into IIIT Hyderabad.

Your chances of getting into NIT is bleak as well even after considering your reservation,you may get seats in some NITs like Durgapur or Hamirpur but your options will be limited.You can check the cut-offs using the below mentioned link-

So I would suggest you to  go for state level counseling for SGFTIs or you can even go for other GFTIs and get your preferred branches.You can use our college predictor tools to find out your chances at other colleges(Link below)-
