Hello

It is difficult to calculate the exact rank. 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.

According to your percentile, your expected rank would be around 86579.

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

Kindly mention your home state and category then we can tell you better about your chances of admission in colleges. Also, you can use the JEE Main COllege Predictor Tool to check your admission chances based on your percentile, home state, category

Good Luck!
