Dear aspirant,

It is very difficult to predict the exact marks on a particular percentile. In every shift it varies according to the toughness of the paper , the quality of students appearing on that particular shift. Like if more intelligent students get on shift -1 let's say then in maybe 100 marks 90 Percentile would be achieved but in a shift which has less intelligent students then in less marks like say 65-70 , 90 percentile would be achieved.

For a general basis you can check out the link given below-

Hi student,

90 percentile in JEE Main means that your marks lie around 68 to 71 marks. Please note that this prediction is only based on previous year trends and can change if the paper pattern or other such things change drastically.
