My rank is 7500 and I got MD Anaesthesia in All India Round 2

Dear friends,
My rank is 7500 and I got MD Anaesthesia in All India Round 2. Last year, DNB Radio went upto 8000+ in Mop Up. Is there a good chance for me to get DNB Radio this year in round 3 or mop up? Since we need to resign our Round 2 seat to be eligible to participate in furthur DNB rounds, I’m very confused whether I can resign the MD Anaesthesia seat or not. Please help with this!
