hi guys, i have applied to several masters places and have been accepted onto a couple of them. however the time for me to accept some offers is running out while i await whether the others will accept me (which i want to get into more than the ones that have already accepted me). is it ok to accept and then reject a masters place later, as i have been told this kind of thing is not accepted at undergrad level (although i understand that is due to the ucas system). any help would be appreciated, thanks.
