hello suhani..

your rank can be predicted using the following way..

It’s difficult to predict actual rank or JEE advanced qualify marks. you may calculate your expected rank by this formula

the percentile is the measurement of knowing the number of student ahead of you or below your score. 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

since cutoff havent been released. a general category student should atleast have a percentile of 85 for qualifying for jee advanced...

hope this helps..

all the best for your bright future..
