Hello

Greetings

Raw scores can Not be calculated by Your Percentile Scores

 Your Rank as Per Current Percentile is 276158  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 442121

 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

Hope this Helps All the Best
