Thanks guys!
I made a couple of mistakes with my navigation, map reading technique etc. This was made worse than usual by the awful visibility at the time. I also wasn't particularly good (to say the least) at getting the picture right during the glide approaches. I hadn't flown in 5 weeks, was tired, nervous, the visibility wasn't great, it was getting dark (well before sunset but still) so don't think I did myself justice. But I managed to pass and the combination of my examiner drilling into me what I got wrong and the horror of getting those things wrong on the test mean I won't be forgetting them in a hurry and will certainly be practicing them to perfection now.
Good luck
caber0, I can only sympathise with your situation, the delays are incredibly stressful and frustrating!
