What is Percentile in JEE Main? Complete Guide (2026)
Percentile is not a percentage of marks. It tells you what percentage of candidates scored equal to or less than you. If you have 99 percentile, it means you scored better than 99% of all candidates who appeared — regardless of how many marks you actually got.
NTA Percentile Formula
This formula is applied separately within each session shift. The results are then normalized across all shifts to produce a single final percentile score on the scoreccard.
Worked Example
Suppose 13.5 lakh candidates appear in a session. If 13,36,500 of them scored equal to or less than you:
Your estimated AIR at 99 percentile with 13.5L candidates would be approximately 13,500 (1% of 13.5L = 13,500 above you).
Why Does NTA Use Percentile and Not Raw Marks?
JEE Main is conducted in multiple shifts with different question papers. To ensure fairness, NTA cannot directly compare raw marks across shifts — a 160 in an easy shift is not the same as a 160 in a tough shift. By converting marks to percentile within each shift first, and then normalizing across shifts, NTA levels the playing field for all candidates regardless of which paper they received.
Common Misconceptions
Myth: “90 percentile means I got 90% marks”
Fact: 90 percentile means you scored better than 90% of candidates. Your actual marks could be 140 out of 300 (just ~47%).
Myth: “Higher marks always means higher percentile”
Fact: True within the same shift, but not across shifts. A 170 in a tough shift can give a higher percentile than 175 in an easy shift.
Myth: “Percentile is the same as percentage of marks scored”
Fact: Completely different. Percentile is a relative rank measure; percentage is an absolute marks measure. NTA uses percentile, not percentage.
