Hey!

There's no release of the score against percentile by NTA as of now. But with 80 percentile you can get 218,892-418,892 rank, considering you are from general category but marks cannot be found as of now.

Kindly wait for another announcement by NTA for more clarification. 

Feel free to ask any more question
