According to your percentile your rank is 507192. But this is just a rough estimate as this time the result will be declared on the basis of two exams. So before JEE mains exam in april the rank cannot be predicted.

My advice to you would be to appear for the april exam to get a better percentile as your current percentile is not good enough. Best of both the exams will be considered as your final percentile.

all the best!
