Sorry, perhaps i should have been more clear; i meant to say that the Scottish
higher education system was perhaps not as dissimilar to the United States' as is that of England and Wales, insofar as one may reasonably, at a Scottish institution, in the first and second years of study, take a varied course load before first committing oneself to a particular discipline in which to 'major' - obviously, however, this excludes the study of medicine, to which students must commit themselves fully from the first instance. I was not commenting on the quality of post-16 qualifications, the degree of specialization or the level of attainment reached at the end of secondary schooling in Scotland.
As for the MCAT (and GAMSAT), which only arrived in the UK with the introduction of GEP programs, i'm sure we can expect higher scores to become de rigeur (facto) once existing GEP courses become more established, new ones are introducted, and UK graduates become more familiar with its assessment criteria and methods.
On international students as a source of income - i don't doubt that many universities use international student fees to subsidize local students or departments (that receive insufficient Government funding subsequent to poor take-up by local students); the cause celebre being the LSE, half whose student body consists of internationals.
2. Edinburgh (when I was a student there) always said that they will only consider internationals from countries where health care is deemed to be inadequate, but it now looks like they are quite open to North Americans and other internationals
and that remains the official party line for most UK medical schools. In reality international students, whether from countries with inadequate facilities for medical education or not, have always been welcome to study at UK medical schools, as have they always been levied extortionate fees for the privilege.
