Guys, I've decided not to do it. I've spent all day on the phone with the lasy, giving names and telling her about my room in Cambridge in case they want to use it. Finally she said they'd decided on an undisclosed location in London, as opposed to Cambridge and I said yeah - great pick me up and I'll do it. Then she asked me for a friend or family member to call her and confirm that I am who I sam I am for legal reasons. So I called my little sister and we chatted about it and she made me sense that if I go and waste half a day in London, I'll regret for the rest of my life if I fail my exams, and that Medicine will affect the rest of my life whereas this is just a fantastic bit of fun. She didn't put it as harshly as that because she is a darling of a person and the best sister a girl could have but I think she made me see sense a bit. I'm now feeling very sad and it was an incredibly tough decision to make so I called the BBC back and left a message on her answer-machine apologising for wasting her time and letting her down at the last minute. I feel awful. I was so looking forward to it.
Please everyone that does go on, make the most of it for those of us who can't and try to get some of our phrases in

It might make up for not being there, and I'll probably get in on Monday evening feeling bad about screwing up my first exam so I'll need cheering up.
I wish the ITT production team would take pity on me and invite me to the Final after my exams, but I felt too shy to ask them that on the phone after dropping them in at such late notice.
I do remember her saying they had someone from Edinburgh, Essex and Durham (so I think, that's startwirler, someone else, and Peach), Now there's a spot available for someone else to enjoy!
Sorry for long post xx
