FAB,
What kind of decissions do you have to make then? If you have another offer (a decent one), I'd suggest you go for that one. Since it's going to take a long while before QR even knows how many applicants can proceed to the next round. And a lot of people are waiting for this. So you have to look at the chance you'll be succesfull. But again, if you've got other options...think about it!
Good luck
