I've learned much more english through the internet and talking to people than I ever could have at school (I'm german). I'm not the best at spelling in general, but I doubt more homework would have fixed it or been worth the investment.

I'm all for learning languages at school though, it's a skill that translates really well in to life unless you learn latin.

Wow, that's a real fatality. But perhaps you should have avoided it. OP was just bringing in his/her experience. Perhaps well worth a spelling error? Your shot was too easy/gratuitous IMHO
