Treadmill or bleep test, it doesn't matter... you're going to be running one way or another. You will most likely do a bleep test at OASC as they get you do to it all at once.
They will understand that you've had you're exams but they will still expect you to know what you're signing up too, what motivates you to join the RAF and this particular branch, have a decent amount of background knowledge on the RAF and what training you will be going through. If you're really stuck on what to prepare you could always talk to your AFCO; if I'm correct you should have already been to a introduction presentation telling you what the RAF expect.
It all comes down too how much effort you are willing to put in and how much you want this...
