with 90%ile your rank gonna be arond 1,02,000 and with this rank you won't be able to get nits with most celebrated branch if are not belonging from the north east region and region like puducherry.

and you may be able to get branch of your choice in new unorganized iiits but as far my experience is concerned ..there would be very high fees which is purely disgusting.

you may find gftis sftis which has even better rank than most of the nits ..even you may get adm in thapar ,shri mata,vaishno devi unersity,.......and if you have done your 12th from delhi you may get nsut iiits there

pls note you haven't mentioned your ategory so ans is given keeping general category in mind .
