Hello

According to your percentile, your expected rank would be around 58223. Rank has been 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.

It should be noted that if the number of candidates for April exam increased to 1200000 then your final rank shall be (100 - your total score) X 1200000/100

Based on the percentile, chances seem to be less of getting a seat in NITs and colleges through JoSAA Counselling. You can get admission through state level counselling. Also, you should appear for the JEE Main April exam and aim to score more to get a good college.

You can use the JEE Main College Predictor tool to check the colleges which you can get and the courses where you have chances of admission on the basis of your percentile, home state, category

Good Luck!
