how jee mains results are shown? by marks? or percentage,

hello bharat;

The JEE main result for the january session is prepared based on the JEE main normalised score i,e percentile which is also referred as NTA score

The percentile score tells you how you have performed compared to all the students appeared for that exam

the formula to calculate the percentile is as follows

Percentile Score of a Candidate =100 x (Number of candidates who secured a raw score (or actual score) EQUAL TO OR LESS than the candidate) / (Total number of candidates who appeared in that session).

It eliminates the inconsistency caused by the variation of difficulty level among all the shifts.

This system was adopted after NTA came into picture before NTA, CBSE used to conduct the JEE mains exam and there was marks system.

the quick reply to your answer is percentile.

NOTE:percentage and percentile are two different terms
