Hey Andy, as it turned out the rest of our group didnt actually get through so I was with 5 guys from the morning group on the next day.
Sorry to hear about the maths but good luck with the retakes. I cant remember exactly what was asked but I know there were general maths problems like pythagorass theorum, long divison, percentages...hmm not sure what else but it was definately the kind of stuff id been looking at on gcse bitesize - just maybe a bit wordier.
Sicky - Our debriefing was about 10 minutes after the interview and then we were free to go. Was it this excel scheme or the oxford app you went for? How did you do?
