Easy to say, but harder to do, "Relax".
Take your time, don't try to do anything special.
The hardest part I found was to slow control and the driven u-turn. But most examiners take you to wide roads to do the u-turn.
Take your time and make sure you have the revs nice and high and remember to control the back brake and keep your head all the way around to see where your going. Try not to look at the curbs.
Also whatever you do, don't panic if you make one mistake, try to forget it and carry on, you won't get failed just for one minor mistake, but if it stays in your mind your more likely to make a few more while worrying about the last.
Also, whatever you do, make sure you do your safety looks whenever you maneuver, especially when you are overtaking parked cars and then pulling back in.
But your probably aware of all this. I was nervous as hell and made a number of minor mistakes and passed first time.
As I said at the start, Relax, take it easy and enjoy. Just think of those months ahead of riding in the nice sunshine.
Off to Thruxton on my VFR750 on Sunday to enjoy the Superbikes. Once you've got your license tomorrow you want to treat yourself and go to a superbike race, nothing better then turning up and parking in a field of a couple of thousand bikes.
All the best
