I think you may as well try. I'm not having my interview for the kensington colleges until december and they dont actually send out offers until late january I think so perhaps its not too late. However, I would send an application NOW
Apply by all means but explain why you are applying late. A lot of places aren't filled until a couple of weeks before you move in because ppl accept places but then don't get into the uni or change their mind or whatever.
Warrane is an interesting place. Very religious so be prepared for that.
