Hello

It would be difficult to tell you about the marks obtained on the basis of your percentile score. However, expected rank can be calculated 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

As per the formula mentioned above, your probable rank would be around 181188.
