Americans know less languages that's for sure, it isn't needed here. What I've always thought and heard is that our grade schools and high schools are inferior but our Universities are much better (they certainly cost enough). I know some US colleges have 10% foreign students. My brother took some classes in colleges in Japan and said they were not very good schools.

Most of the tests that put Americans as uninformed and done in grade school or highschool.

For geography, I seem to remember most of the time being spent on learning all the states and their capitals.
