I don't know about France, but in The Netherlands where we have a similar system in my opinion it is just quite hard to get all questions on a test right. Even the smartest most hard working kids do not often get every single question right. Ofcourse if the math test is just solving 20 similar equations then the smart kids will easily solve them all and get a 10/10, but a math test is never solving 20 equations. Do kids that get an A(+) in the states have the correct answer with the correct explanation (deriviation) for every question? If so it could be they've just studied harder, culture can do funny things.
