Be very aware that although the course may be taught in English, the rest of the University and the city you are in will not be English speaking.
Do not underestimate the sense of isolation, homesickness and culture/communication problems this will create. The reality of studying in a different country where you don't speak the local language is very different from what the Universities offering such courses might imply. Remember - all they are interested in is your money and they will always suggest that studying overseas is problem-free.
Also remember that if you start a Medicine degree overseas, you will not be able to transfer back to a UK Uni to complete your degree here, so if you start a Medicine degree in Romania or Hungary you'll be there for the entire course, and you wont be part of the NHS system for post-qualification foundation years.
