Students from England now have to pay around £9000 for all undergraduate courses including Medical degree course fees (attending Scottish universities such as Edinburgh and Dundee Medical Schools) and students from Scotland will not pay fees.

I guess the main difference between the Medical education in the UK and the USA is that education for the treatment of penetrating gun shot wounds is sorely lacking in the UK unless you happen to be studying at a London or Manchester Medical School. The Scottish NHS ethos (such as free prescriptions for everyone) might be a bit of a downer though if the aim of becoming a medical professional is about maximising your own personal wealth.

The University of St Andrews Medical School might be worthwhile investigating simply because of its location and size and the relaxed atmosphere whilst studying there (very little distraction to study). They have been teaching Medicine there for about 600 years.
