Hello candidate,

The rank and percentile is calculated into different ways for the JEE Mains examination as suggested by the national testing agency which conducts the examination.

The Percentile is a symbol representation that out of 100, how far behind you are in terms of marks from the the top scoring student.

The rank is calculated by the formula (100- Percentile)* total number of students appearing in that session/ 100.

Hope it helps!!
