I'm from Europe and I didn't learn English in class. Instead I learned it from the AD&D (2nd edition) material. Together with a class mate who also had DM aspirations, we swapped and traded material through BBSes.
We were so far ahead of the class, the teacher would set us apart and just let us do whatever we wanted. As long as we whispered, we could talk and read separate from the rest of the class. Of course that got us nasty looks, but we got to talk for a solid two hours about Planescape or Forgotten Realms.
After class, we'd ask the teacher words that we couldn't find in the dictionary. He couldn't them either. I remember finding out what "to be marooned" meant, ahead of the teacher.
I also remember that me and my gaming buddy got an A- on our final exams. After the verbal part of the exam, the teacher said he was a bit disappointed in my verbal skills. But because he knew I had it in me, he'd give me an A-.
I stopped gaming when college started, I couldn't find a gaming group. After almost twenty years, I found out my current employer has a group of colleagues who regularly play Pathfinder, and I joined them. I'm playing a fifth level thief, and it's an absolute blast.
