Yeah, unfortunately that misconception isn't really ever going to go away and the Irish students don't seem to understand that international students don't take spots away from them and we aren't competing with them for places. Perhaps in general, they should reduce the number of international students and thus reduce class sizes, or make more spots open for Irish students (50% is a bit high!). But as it stands, international students are funding 73% of Irish medical education expenses so getting by that will be tricky for them.
The first post-grad med ed program is meant to start in 2007, but don't really know if they're on a realistic time plan or not. At the moment, there seems to be a push for a 5-yr. curriculum (for everyone) instead of a 6 yr. one. But I know some people in science who entered science so they could take advantage of a post-grad course.
