Hello Shruti,

Mop up round is a round or a list basically that comes out after all the rounds are done.

It is for filling all the vacant seats that have been left out after the rounds. Sometimes students leave their seats due to some reasons and the seats become vacant. The state council gives the students a date up to which the students can leave their seat without paying a fine. So the seats that remain empty are allotted to students. There are very few seats like that. So it's basically to wind up all the seats and finish the counselling. So nothing can be said regarding the rank it varies each year.
