I just finished re-reading the Goblet of Fire, and it sounds like O.W.L.S.(Ordinary Wizarding Levels) = GCSEs. But I don't remember what the wizard equivalent of a university is. They probably just get apprenticeships instead.

I believe there's a hero in all of us that keeps us honest, gives us strength, makes us noble, and finally allows us to die with pride, even though sometimes we have to be steady and give up the thing we want the most. Even our dreams. -- Aunt May, Spider-Man 2
