Hello Akhtar

As of now we cannot decide whether you will get the NITs or not, because the Rank would change Either Your Percentile Score is Increases in the next attempt or Number of Student increases in the Next attempt. So you have to wait till the April exams get over and the overall rank get published. You can calculate the predicted rank  using the below formula.

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