Seriously, I can't stop. There's all manner of quizzes on there. My latest obsession is countries of the world quiz. I won't rest until I name all 196.
(Current highest score 152.)
Should I get a life? On the plus side, it's seriously improving my geography knowledge.I was a WHIZZ on Pointless earlier today when they asked to name countries beginning with the letter C. 
Take the quiz. What's your score?
