No, no. Not Google Maps. Google Maps is not going to help you here. Those old-school paper maps? Much more helpful.
Why? Because it's a Name X In Y Minutes quiz today. You're going to be given a list of 144 geographical abbreviations, and your task is to say what those abbreviations stand for. You have 20 minutes. (My score: 128.)
And if you think it's just going to be countries, you are in for a shock. There are administrative divisions, terms for landforms and bodies of water, anything and everything that you might see on a map.
