I started studying German in 5th grade, actually, so last couple of years of elementary school! And then I kept studying it until 9th grade^, and graduated with an A - unfortunately, lack of practise means I've forgotten a lot of it. >.< If you gave me a newspaper in German, I would at least be able to understand the gist of what's being written about.
^Sweden doesn't really have the same kind of highschool-system as the US does. I went to one school for 1st to 6ht grade, then moved to another school for "högstadiet" (which would translate as "highschool", even though it isn't the same as the US highschool) for 7th to 9th grade, and then went to "gymnasiet" for another 3 years - and when you get to the gymnasium-stage, you get to specialise in a specific subject - I chose art, and got a v. basic art school education. ... Note that a "gymnasium"-school in Swedish doesn't actually have anything to do with gym-classes. I have no idea why we ended up with that word for it, but there you go. I only studied Swedish and English in gymnasiet, though - I dropped German classes after 9th grade.
