Thanks guys.
I think each and every examiner is so different, it's hard to accurately gauge what they are looking for. For instance, my minor with the handbrake could have been a fail under another examiner (in fact, my instructor said he had a student who was failed for such a thing). I took a mock test with my instructor a few days ago, and failed with 6 minor faults and 1 major. You would think that this would be a knock to my confidence, but he told me that if my examiner had to fail me they would be sorry to do so because they would know I was a capable driver. This really helped boost my confidence.
My examiner was very friendly, and he seemed to accept that I was a capable driver within the first ten minutes of driving. There were a few times where I made little mistakes my instructor had previously corrected me on (signalling a bit too early, not checking my mirrors before signalling) which my examiner didn't mark at all. At the end of the test, I mentioned I was sad it was over as I was enjoying our little chat, and he told me I was driving so well that he was easily able to conversation, (In fact, I think he was a bit distracted as he would sometimes give me directions and continue talking about his travel plans in same breath!) so I think if your examiner seems relaxed enough to have a chat, take it as a good sign.
I can't stress how much confidence was the key to driving for me. I had some pretty awful moment of sheer panic whilst driving over here. But one morning I just woke up and thought "Don't be ridiculous, of course you can drive!", and after that I felt so calm and cool when I would otherwise enter complete panic shut-down mode.
Good luck to everyone currently taking lessons and exams. I know EXACTLY how you feel, but it CAN be done!
(btw, I had 7 hours of lessons, but had done bits of driving before that)
