Oakleigh's routes are arguably the easiest in Vic. My instructor took me on all of them over the last few weeks leading up to the test so there was no area i wasn't familiar with.
OT: the guy took mine to another desk so i couldn't see what he was doing. Then he took it to another guy to ask some questions, so i shat myself... thinking it'd get rejected, but then he said it's all good. Then after the drive test, he said "you've obviously done the hours and not faked them like a lot of other people". Just do the hours, don't endanger yourself and other road users. My entire book was fake, but i actually did about 600 hours so it was the logbook check that was the hurdle. Just be smart about which office you book in and usually go around lunch time (mine was 1pm), there was no other cars on the road. Good luck!
