Hello dear aspirant

Hope you’re doing well

Firstly, thats a great percentile you scored.
as per your percentile of 98.5 your predicted JEE mains rank would come somewhere between 15345 to 17250.
it would still be difficult to get into IIIT Hyderabad because you know how high the competition is.

To know your best possible colleges or university under this rank please use the JEE mains college predictor tool
