Hlw sir .....how to check percentage ???

NTA declares percentile score which is different for different session .Score in your card is your percentile score in your session.,total 8 session in which 1st phase of jee mains held this year.Percentile score represent percentage of candidate score equal to or less than your raw score in your session.You can calculate your raw score using this formula..Your score = ( your percentile total number of candidate in your session)(number of candidate  in your session who score equal to irless than your raw score100).
Percentage can't be calculated right now .As score is not released yet but NTA.So wait till NTA declares raw score
You can ask if you have any other doubt.
GOOD LUCK!
