Hey there,
Statistically speaking Warwick offers the largest number of places for GEM so it is likely with the combination of experience and grades that you be offered an interview. However this will also be dependent on your UCAT score. With regards to other medical schools if you have a really good UCAT score it honestly really depends on where you would like to go.
A few other things to take into account are the following:
- city v.s. campus uni
- course structure for medicine: integrated, PBL, CBL, traditional
- distance from home: how often do you think you'll want to go home and how much will it cost you
- city: how big; what is there to do; transport links
- societies: both medical and non-medical
- placement hospitals (although remember once you graduate you can apply to go anywhere)
- size of medical school
