Hello Yadnya,

It is not possible to find out one's score from the JEE Main percentile as percentile means that if there are 100 people sitting for an exam and your percentile is 90 this would actually mean that you have scored more or same than 90 other people sitting in that exam. So the percentile changes as the number of students change. The score cannot be predicted but we help you calculate your probable rank. Just provide us with your percentile score and leave the rest upon us. 

Good luck!
