Woman at admissions, just phoned 2 mins ago (don't know if any of this has been said before, haven't been keeping up to date with this thread, sorry!):
"We do not have a cut-off score as such, they are simply ranked in order. However, I can tell you the UKCAT scores this year are much higher than last year and it's unlikely you will be called for interview if your UKCAT score is below 2610."
I have 2540, dawg nabbit.
