30 prsantile convert into marks
Hello Aspirant,
The calculation of the marks & rank would be difficult based on your percentile. 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 1200000/100Your probable rank will be 6,08,307
I would suggest you to appear for JEE Main 2020 April session again.
Good Luck!
