Hello

Greetings

Your percentile is 87.2 It means 87.2% student of the Total student appeared for the Exam are Behind You Therefore 12.8% students of the Total students appeared for the exam are Ahead of You, Therefore Your calculated Approximate rank is 111932

But Note that This is Not Your Final Rank Your Rank would change Either Your Percentile Score is Increases in the next attempt or Number of Student increases in the Next attempt If the Number of Student Increases to 1400000 and Your percentile remains same then Your New rank would be 179200

As per Your current Performance You may be eligible for JEE Advance But the final cutoff will be released once the JEE Main April gets Over

If Your Percentile Score Increases in the Next attempt Then Your Rank would Be calculated By the Following Formula

(100 - your total percentile score (Higher of two)) X Student appeared in JEE Main/100

At this rank It is Not possible to get admission into any NIT, Please try better in the next attempt of JEE Main

You should Try to get more than 98 percentile for NIT

Hope this Helps All the Best
