As of now its tough to say because the analysis and also cutoffs change every year due to many factors like total students appearing for exam,difficulty level of paper etc.as you did not mention your category considering you from gen category now based on your rank which is aroung 2.5 lakh-2.86 lakh you will have nearly very low to no chances to fetch seat in nits.you need a better score atleast 96-98+ percentile to fetch seat .work hard and improve your score in upcoming jeemain sessions.  for more information refer to:
