Passed!!
got up this morning & it was snowing, drove over snow covered hills & almost turned back but incredibly the test happened. Squally, turbulent weather, loads of lift & sink, I was all over the place but somehow managed to get where I wanted to. Realised after about an hour or so that I had almost certainly passed so was able to relax - had a bit of worthwhile instruction on glide approaches by my instructor & a demo at the end!
Lost 3l of sweat, just about rehydrated now.
Many thanks to you all for your support, it was very helpful last night. Many of you were right - its the big things they seem to be interested in, not the minutiae.
I didn't see the bill coming though - £170 plus another £70 for the night rating!!! I almost passed out from shock!
