Hey Steve,
Tough luck mate, but the good news is that I'm booking myself in on Friday so at least we'll be off them at the same time.
Gotta admit though, I did my training at Walkley Heights (Wright Road - same as 7THSIN) and they drew out the exact exercises we'd have to do and I took pictures

They also said to use the bikes they provided - I got told a couple of times and everyone else who I've talked to who just passed has told me to use their supplied buzzboxes as our bikes just won't have the turning circle for it
Bit annoying considering you spend x months getting used to a style of bike and then have to somewhat re-learn a few things just to pass the test.
I was under the impression that you could attempt it twice without having to pay, though - it's just the time inconvenience.
