my nta score is 92.967327 what would be my obc category rank not general rank.

Hello

Calculating the category rank is tough as it depends on various factors. As of now, only the expected overall rank can be predicted using the formula mentioned below:

100 - your total percentile score is the percentage  of people ahead of you. 869010 are the number of candidates appeared for Jan exam.
So rank formula is (100 - your total score) X 869010 /100.

If the number of candidates for April exam increased to 1200000 then your final rank shall be (100 - your total score) X 1200000/100

Do let us know if you have any other queries.

Good Luck!
