Still, QMUL use UKCAT pretty heavily. I've emailed them:
1.Thank you for your interest in Barts and the London. There is no UKCAT cut off per se. It is decided on a year by year basis, and is dependant upon the scores of the candidates and the number of candidates we would like to interview. As such, the cut off score changes every year.
We use the UKCAT very heavily, as we use it to determine who we are going to interview.
I couldn't squeeze it out of them after several emails whether or not they are using a cut-off point this year.
