Hello Aspirant,

The exact prediction would be difficult about the exact rank & admission possibilities. 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 5,68,853.

As the chances are very less to get NITs, IIITs & GFTIs, You can go for the state level counselling like Punjab, Haryana, MP etc.

I would also suggest you to appear for JEE Main 2020 April session again.

You can check your admission possibilities in state level counselling with JEE Main College Predictor tool given below.

Good Luck!
