Hello Aspirant,

The calculation of the marks & qualified score would be difficult to predict based on your percentile. But as a general category this score seems not enough to qualify.

You may calculate your expected rank by this formula.

100 - your total percentile score is the percentage  of people ahead of you. 874469 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

Using the formula

(100 - your total score) X 869010 /100

Your probable rank will be 2,01,871.

Good Luck!
