Namely, the countries of the world? I just did this quiz and got 157/197!

I'm confident I could pinpoint about 50 of those and could probably give you a few facts about them. Maybe 50 more I could give a good guess as to where they are. Another 50 I could tell you the continent, and that'd be it. The last 7 I just know they're somewhere in the world and it's anybody's guess as to where! I know shockingly little about Europe, Anything east of Austria or Italy I'm very vague on. We didn't really 'do' Geography at school - it was all 'sustainability', 'tectonic plates' and 'long-shore drift', nothing about the actual countries, resources and people there. My New Year's resolution to the educate myself on geography of the world.
