Shan, be careful with inferences. The acceptance scores to UQ for Americans really hasn't changed from when I knew the stats (2004-2006) compared to what's been claimed for the past year. Meanwhile, I think it's still the case that only 1 person from UQ in the past 5 years (except I don't know about this past year) has failed the USMLE.
I think it's important to remember that those who have come to Australia with the intention of returning are self-selected, that is, are probably pretty motivated to work hard enough to get above average scores. On average, that is
. Similarly the percentage of Canadians who've gotten spots in Canada in the past couple of years from UQ is way above the international average (e.g., 9/11 for 2009 if I'm recalling my own past posts correctly). Such self-selection bias may also help explain part of Flinders' high scores.
The US feds have in recent years been requiring foreign schools to collect information on their American students' USMLE scores, as part of continual assessment of whether to allow their students to get Stafford loans. So unless that policy has changed recently, the schools at least
ask students for their scores, and collate them (self-reported as they are). Whether the schools want to share that data is another matter though, just as few schools here will publicize the GAMSAT scores or GPAs of their entry class (unlike in the US where it's easy to find such data). It can't hurt to ask, though.
I didn't realize Winged Scapula was FKA Kimberli! Cheers.
