Haven't got one, who's supplying you with the mock interview?
Ah sorry forgot to say, so if you’ve done an outreach programme with bristol. ( Access to Bristol , Bristol Summer School , Bristol Scholars) you’re eligible for guaranteed interview regardless of ucat score as long as you achieve the minimum grade requirements for both the standard and gateway course. This is followed up by support to help you through mock interviews , tutoring if your on scholars and much more. This was what I was told by them.
