Hello dear student,

It's difficult to predict but as you have reservation so there is a chance . But as you got 80 percentile so the rank you can get is in the range of 173,700- 173,900.

While you also try for the government colleges accept the marks of JEE mains. I hope this will be helpful for you dear student.

If you want to calculate your rank by your own then dear student you can do it as 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.

Thank you
