I failed my first attempt at Morley, but passed on my second at Willagee.
The assessor for my first test was quite unfriendly, to the point of rudeness. Don't know if he's like that all the time, but it certainly didn't help that he seemed to be in a bad mood also.
However on my second attempt, the assessor (different guy from the first) was friendly and jovial, and I thoroughly enjoyed the ride, and passing the test was a bonus!
I agree with the points made by other posters also. If they know you have had sufficient lessons, and can prove that you are safe and know the road rules, you will most likely pass, so long as you don't stuff up your "figure o's"!
