hello aspirant,

84 percentile would fetch you a rank around 163680-184000. ,now these are based on previous year analysis .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.now as you did not mention your category considering you from gen category based on your rank you will have nearly very low to no chances to fetch seat in nits unless you have some category benefits.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:

hope this helps,

thankyou.
