Hi Aspirant,
Hope you are doing great as per the question asked by you as you are OBC+PWD candidate you should have percentile around 85-90 to get a secure seat in top NIT's, IIITs, GFTIs etc. but don't concentrate on percentile try to score more and more as you can as it will help you alot if the cutoff increases. Because cutoff is not fixed for every year.
Hope you found this answer useful.Stay motivated stay positive.
All the best!
