As long as you meet the minimum (not sure if Edinburgh is AAA or A*AA) I don't think they will care how much you are above it, the majority of vet schools (bar Cambridge) do not give any extra points for being above in the minimum requirements and it is just a check box to move onto the next stage of admissions. Where are you from? As Glasgow and Edinburgh have a tiny number of places available for non-Scottish UK students so applying to both is not advised if you are of that criteria, so that may be something to bear in mind. I don't actually know much at all about how anything is done at Edinburgh as I never considered it so I can't give you any comparisons but I am a third year Liverpool student if you have any questions I am happy to answer. With the admissions process at Liverpool as long as you meet the minimum criteria there is no other forms beside the work experience form so everyone is invited to interview so your offer is 100% based on that, whether you like a guaranteed interview or prefer to have some other forms is up to you.
