Hello Aspirant,

If MCC opens a new round (choice-filling window), you get the unlock/modify choices option only during that choice-filling window - i.e., after Round registration opens, and before the official choice locking deadline. If you took an AIQ seat in Round-1, you can still do new choice-filling/upgradation in Round-2 (so shifting to a deemed college is feasible during Round-2 choice filling). When Round-2 registration/choice filling is active, keep checking Candidate Login → Choice Filling on mcc.nic.in; the portal will show the unlock/modify choices (the buttons) and the exact deadline.

Hello,

Yes, you can change your choice in Round 2. Even if you got a seat in Round 1 through All India Quota, you can still apply for deemed universities in Round 2.

The "unlock" option in MCC counselling is usually available during the choice filling period of each round. You can request unlock only once, and after that you have to re-submit and lock your choices before the deadline.

So, it comes when choice filling for that round is going on.

Hope it helps !
