According to 150 Marks in JEE Mains 2021 your Percentile would be in the range: 97.56 - 98.62

Now if we consider 98.62 percentile then your CRL Rank would be in the range- 14117 - 15870

And if we consider 97.56 percentile then your CRL Rank would be in the range- 24961 - 28060

(This rank range may or may not be accurate , but it's  just rough idea based on-
