Also Germany.
I learned english in school but only enough to be able to read it.
Once I started reading user submitted short stories (lile fan fics but different) my grammar really improved.
Nowadays the content I consume is basically 90% english based.
Just my capitalization and grammar structure sucks. Also my vocal skills as I have no one to talk to.
But: I really have to thank my last Grundschul and Realschul english teachers. Without those two I may have never got into english that well.
