Nice, well just rememebr to pretend your an old slow driver for the test and always come to a complete stop at stop signs and unbroken lines. I know ppl who have failed for that. Also remember to head check and use your mirrors. They want to see all the safty aspects of driving so keep it slow, steady and smooth and you'll be fine. Main peice of advide I can give you though is relax, if your relaxed you'll do much better. It's not that scary really, no diff to driving on your L's, all you have to do is show them what you've learnt.
Still.....your ARE naughty for driving that beast on your P's. Do us a favour and stay out of the headlines ok. Before you put the foot down just think how much fun it is sitting at home whishing you had a skyline to play with
