Hello Aspirant,

To be very honest, one can't predict the jee mains marks on the basis of percentile because some very important factors play an important role in it like every year the quality of candidates is different, the difficulty level of the paper is different ,number of seats of the college .

But still if i want to give range of marks considering you as OBC category candidate , then you should atleast score 170+ in order to get 99 percentile.
