If you do not want to participate in Round 2, you dont have to fill the choices for Round 2. NMC will start its Round 2 process from November 18th. So you just dont have to fill the choices. Then once after all the rounds of Counselling are over, then the security deposit will be refunded to the same account from which the payment was made from. NMC will release the list of eligible candidates who are eligible for refund. But you can opt for State Counselling.
