The course is extremely difficult, much harder than here so don't go expecting it to be an easy option. An ex of mine studied there for 2 years before deciding to come back here for medicine, he used to laugh at how easy it was here on a grad course compared to over there so that should give you an idea of the difficulty. He had to start from 1st year again though as there is no chance of a transfer at any point and he only got on a grad course because he had another degree already. Like others have said you have to be fluent by clinicals but you do get lessons in the language throughout pre-clinicals. I'm not sure about drop out rates but a lot of people end up repeating years, there is even a section in the prospectus about repeating because so many people do. You also have to consider job prospects after graduating as that kind of thing is changing quite a lot at the mo. Currently if you come from a non EU country even if you trained here you can't really get a job here after the foundation years. So, I wouldn't be that surprised if in a few years you couldn't get a job here if you had trained in another country.
