Hello Siddhant

Congrats for 83.58 percentile in JEE mains 2019

We can't say that you are qualified or not because NTA has not released any Cutt off marks or rank list to say that you are qualified or not .NTA will display this list after the second attempt in april.

There is a pedicted formula from our team to predict rank

 Total No of students = 874469

Formula

Probable Rank= ( 100 - NTA percentile ) x 874469 / 100

So your predicted rank  = 143587 approx

Our Team predicted that the qualify cutt off would be above 85 percentile .But it just a prediction.

So please wait till april.

I hope you get my point.

Good Luck!!!
