Your percentile is 75 It means 75% student of the Total student appeared for the Exam are Behind You Therefore 25% students of the Total students appeared for the exam are Ahead of You, Therefore Your calculated Approximate rank is 218617

 But Note that this rank is Not the 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 remain same then Your New rank would be 350000

Your rank is Not Good and You should Try in the Next attempt of JEE Main which is JEE Main April and Try to perform well, THe actual cutoff will be released once 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
