I've applied to two places for my foundation art degree in Manchester, Manchester City College and Manchester Met. City College accepted me straight away and i got a letter yesterday asking me if i want to accept the place. Thing is i wont hear back from Manchester Met for a few weeks yet, and i dont want to accept my place at city college untill i know whether MMU excepted me.
Is there a time limit on these places? Like if i wait a few weeks untill i hear back from MMU will my place be gone and City College? I dont want to accept my place at City College only to call up and say i dont want to go because MMU excepted me.

Help?
