Good luck for the test - dunno whether this will give you confidence or not, but it seems to me completely random whether you pass or not - I drove much worse on my second test (and passed) yet failed my first, where I drove brilliantly, but was given a major fault for going the wrong way.
I passed my motorbike test last week, and Lee failed, but I can guarantee he rode much better than I did - I was stunned when the examiner told me I'd passed.
On the equally interesting subject of sandwiches, I ordered a ham, smoked cheese and tomato/chilli chutney sandwich for lunch (which is usually superb) but despite me saying tomato and chilli chutney about 5 times, it came with mango chutney instead. It was interesting, still quite nice, but I don't think I'd get it again.
