For NITs and IIITs you need to register yourself for Joint Seat Allocation Authority counselling. For JoSAA counselling you need to clear JEE Mains cutoff which was 89 percentile for general category and it changes category wise. So with you JEE Mains percentile i think you won't be able to register for JoSAA counselling 2019

sorry to say priyansi but with this rank and score you cannot get any nit college in india and so filling josaa councelling is just a waste of time and money but it rank their is a chance you can get government college but you cannot get into any good nit
