Hello,

You can calculate your rank by using the below formula

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

so your predicted rank will be around 110364. This your general rank and will change after jee mains april.
