Nice. Now there's this. I went from an American high school to a Dutch university (admittedly a decade and a half ago, but still) and was shocked to discover that Dutch students as a matter of principle refuse to put in any effort that will push them beyond the barest minimum above a passing grade whereas the Americans I was used to at least tried to shoot for, say, a C, and if they were especially ambitious, a B or even a B+.
(that said, at the "American high school" I went to there were also a large number of Indian, Taiwanese and Korean kids and, like the article suggests, they made it a matter of principle to never receive less than an A+ in any course they took - although, that said, they rarely enrolled in courses where their chances of receiving such grades were in peril: very few Taiwanese and Koreans took history or English literature, for example)
