Hello aspirant

Hope you are doing great there . Since you have not mentioned any category therefore considering you to be a general category candidate , I am really very sorry to say this but with this percentile you are not eligible for jee advance 2021 . The tentative cut off for jee main 2021 is around 89 percentile . But if somehow the cut off goes down then you might be able to appear for jee advance 2021.

I hope my answer helps

Wish you all the very best!
