don't really know. usually it takes a week for the letters to be delivered and sometimes loooooooooooong time for them to consider your application. so you v still got the opportunity to be accepted
You may well have to wait a long time, but if you've been waiting for over a month then nobody is going to think you're rude or pushy for sending them a note asking about the progress of your application.
I've been waiting more than 3 months for one of my applications, and haven't been given any feedback whatsoever, despite having specifically asked for some!
