Hello Aspirant,

The calculation of the marks & rank would be difficult based on your percentile. 869010 candidates appeared for JEE Main January session 2020. Using the formula given below

(100-your total percentile) X 869010/100

Your probable rank will be 408,434

I would suggest you to appear for JEE Main April Session 2020 which application form is expected to start from 7th February, 2020. Try to score well in entrance Exam.

Good Luck!
