I thought I'd failed my driving test for sure... and I burst into tears when the examiner said I'd passed first time. You may well have performed better than you think. In fact I will be surprised if you haven't done well, because you're easily one of the most intelligent people I've ever known. I mean, how else can anyone memorise and recite great chunks of Blackadder? And who's the one who's self-taught in all sorts of computer programming (that I'm too dim to get my head around)? You, that's who!
