Cheers for all the support.
I agree with you all about being a better rider for it, I'm still learning loads every time I go out, who said this was easy? and d'ya know what?, I'm glad it's hard, it proves to me that it is not as simple to get a licence as I first thought.
I will clarify my 'fail' for you.
As I shoulder checked I steared slightly and pulled accross the white line. The problem was that, as I crossed the line I was probably only 10 yards behind the car which had just overtaken me. When I spoke to my instructor about it, he said "I do that on a daily basis, but I know what I'm doing (been riding 28 years(fair point)) and you are under test conditions." So basically the long and short of it, is, There wasn't actually much wrong with the manouvre, it was just not something I should have done on my test.
What really hacked me off was, the 17 year old child who done his directly after me had 12 minor faults and passed.
Bloody kids!!!!!! (not really, fair play to him.)
Anyway, thanks for all the support and I will persevere until I can call myself a biker. Probably not a 'REAL BIKER' but a biker never the less.
Thanks guys and girls.
