Universities vary in their requirements for GCSEs. Some will calculate the score from the 8 highest GCSE grades you get, others will look at all of them and then others will focus more on the core subjects like Maths, English and Sciences only

We taught several students last year who were applying for veterinary medicine. The interviews tended to focus on broadly the same domains as medical school interviews. However, there are some important considerations. One of these is the financial impact of care. Whilst this is increasing becoming a consideration in deciding which treatments the NHS can fund, you are more likely to be exposed to such a consideration in a veterinary school MMI interview.

Medical schools are increasingly using live actors in MMI stations. A common scenario is where you have to use your initiative to resolve a conflict or a dilemma. From our knowledge of such assessments, the actor usually is briefed before the station and will have been told how to respond to what candidates say. They will usually not give away any information unless they are specifically asked.
