Hello,

Considering your query is about second round seat allotment of All India Quota Counselling for admission to MBBS/BDS colleges. If a candidate is allotted a seat in 2nd round of counselling and does not want to join the allotted seat he can still exit with forfeiture (losing security amount deposited) and  once candidate joined the allotted seat would not be eligible for resigning/surrender of joined seat.

Hope this helps.

Good Luck!
