Hello Aspirant ,

Calculating the score through NAT percentile is not possible. You should wait for the official results to be out.

But there is a simple formula through which we can calculate the approximate rank using NAT percentile.

JEE Main 2019 rank (probable) = (100- NTA percentile score ) X 874469 /100

In your case your rank comes out to be approx. 594000.

Good Luck for you April Attempt!
