OK, I fully admit that this is very lame on my part. I missed 191 countries. And yes, poor Uzbekistan and Tunisia and Ecuador, I should have remembered you. But seriously? I've never heard of Pridnestrovie. Or Nagorno-Karabakh. Or Svalbard. And because the test requires correct spelling, even some of the names I could think of, I couldn't spell quickly enough.
The truth is, I kind of spaced on most of Africa. I think I need to brush up on my geography.
