The Geography Challenge - this is quite fun, plus there's a scorecard at the end of the quiz..
To join the Geography Challenge in support of your country, you simply need to select which country you will be representing and take the quiz. The quiz consists of trying to locate 10 randomly selected countries on a map of the world. It is different every time. As a non-member, you may take it up to 3 times per day, but no cheating.
the countdown begins
Not bad, eh?
