Optimistic title for what is still a very small trend. I hope the trend gets bigger and UK universities realise that their fees are unsustainable. And since there are already plenty of foreign-degree graduates working in the UK, conversion of grades should not pose a problem. Another very important point mentioned in passing in the article: in Europe fees may be small or zero, but the pass rates are much lower. You really have to study to pass from year one to year two!
By the way, in the 1990s and 2000s Bulgaria’s medical schools already had lots of international students, but they were mostly from Macedonia, Turkey and Greece, and a few ethnic Bulgarians from Bessarabia. Local students used to say that oftentimes the internationals had an easier time passing exams.
