pugwash: You do indeed get a diagramming paper. It's been a little while since I did Stage 1 so I can't remember exactly, but you do have to carry out each command in order (but what you are applying the command to will change from the starting sequence). Basically, the instructions on the day are the same as those sent in the practice document (but there are different symbols and commands). If you can get the practice examples right, you'll be fine.
bartkobe/bzz1: I got my results a few days after doing the questionnaire (if you want exact dates, look up my previous posts as they're in one of them). It seems there are a lot of people doing Stage 1 about now (and not much talk of Stage 2/Stage 3) so perhaps there's a bit of a backlog? As marco888 says, once 15 working days are up, give them a call!
rossbrereton18: As far as I can remember, I managed to get through all the data checking, all the motivation questions, missed out 5 cubes and 2 diagramming questions (ish!). How many I got right, I'll probably never know...
