You can register for Mop Up Round. Eligible Candidates for Mop Up round:

1. Candidates who registered for Round 1 and opted for Free exit

2. Candidates who registered in Round and exited with forfeiture of fees

3. Candidates who did not register for Round 1 or Round 2,

4. Candidates who registered either for Round 1 or Round 2 but did not get a seat

Candidates who have already joined in Round 2 of AIQ/Deemed/Central Universities/AIIMS/JIPMER are not eligible for Mop Up Round. https://mcc.nic.in/UGCounselling/Documents/UGSchemeFinal.pdf

The only catch is that you cannot quit a seat allotted in Mop up round. If you do not want to report and join the allotted seat, you may have to forfeit the security deposit. So it is a conscious decision that you have to make between All India Counselling and State Counselling. In the mop up round  vacant seats of Deemed Universities, Central Universities, IP Quota of ESIC Medical Colleges, vacant seats of AIIMS and JIPMER are filled.  But at State level, you still can have a chance to secure a seat in GMC based on your score, rank in the merit list and preferences. So please do think and take a call.
