Hi aspirant,

Mop up rounds is conducted by MCC in order to fill the vacant seats available in various medical colleges after the two rounds of counselling. See actually any person who has qualified neet can apply for the mop up round, it not matters that if he or she is allotted a seat or not or participated in previous rounds. The only case a person is not allowed to participate in the mop up round is that if he or she has filled up status retention form and confirmed his admission to the college.

Since you have mentioned that you didn't got into the previously allotted college, so you can definitely apply for mop up round.

Hope it helps!
