AACCC will conduct Counselling for 15% of All India Quota seats of Government, Government Aided, Central Universities, National Institutes and 100% seats of Deemed Universities and internal seats of Delhi University. And there is an option of Free Exit for Round 1. Free Exit is nothing but If a Candidate has been allotted a seat and even if the Candidate does not report/join the allotted college he/she would not be penalised and will be eligible for subsequent round. So if you do not want to report to the College, you can opt for Free Exit. Or you can report to the College and opt for upgrade which means in the Round 2, if you get a better seat, the seat allotted in Round 1 gets automatically cancelled. But you needn't register for Round 2. You can fill in the choices when the schedule is released. But please only fill the Colleges that you would like to take admission in Round 2 because if you do not report to the College in Round 2, you will be penalised and you will have to forfeit your security deposit.
