Hello Aspirant,

First of all let me clear you with the meaning of percentile, percentile is nothing but a percentage of candidates having score equal or less than you, so if you are getting 98 percentile then it means that 98% candidates have scored less marks then you in JEE-Main.

Now let me explain you the way of calculating result through an example. Suppose there are 4 shifts, some were difficult and some were easy, Now in difficult shifts it would be difficult to score more marks as compared to that of easy shifts, now if the shift would be difficult then it would be difficult for each and every candidate appearing in that shift therefore they all will ultimately score less marks as compared to the candidates scoring in easier shifts, so to remove this partiality the percentile system has been adopted.

Because of this it is much possible that candidate of easy shift on scoring 105 marks get only 90 percentile but on the same place any candidate of difficult shift might get 95 percentile even on 100 marks. So what all maters is difficulty level of paper.
