My main percentile is 90 then what will be the my marks

Hii

The raw scores have not yet be announced by NTA, only th percentiles are shown in the result card which has been released. The final result, rank list and scores would be declared only after conducting the April session of JEE Mains.
As of now you can calculate your estimated rank with following formula
100- your score * 874469 /100
As per this, your rank would be 87446
The rank might change after the final result because the no. of students will increase in april session as well as the marks might vary as the best of two scores would be used.
Since this years cutoffs are yet to be released, as per preious year cutoffs, 90 percentile is a decent score to get admission into good engineering colleges. But if you are not satisfied, you can try once again in april session and improve your score.
You can refer to this link for more details. https://engineering.careers360.com/articles/jee-main-marks-vs-rank

Hope this helps
Thanks!!

Hello

Greetings

Absolute marks cannot be calculated from the Percentile scores since the percentile scores tell Your relative position among the students appeared in the exams and It does not consider Your absolute score directly in calculating the percentile score, therefore, one can not calculate Absolute score from the percentile score.

Hope This Helps All the best.
