No, I don't know a lot of country capitals. I'd be surprised if i could name more than half.
82 ~42%. Forgot some, but a majority I did not know and did not even look remotely familiar. Got most of Europe and South America, some of Asia and North America, and a few in Africa and Oceania (basically just Australia and New Zealand, both of which I tried several major cities before finding the right one. I can name all of the capital cities in Australia and my first choice for the capital of Australia will still be Sydney if it weren't for the fact that I knew Melbourne used to be the capital. Heck, most Australian AGers are probably from Sydney, Melbourne, Brisbane, and Adelaide. Is there anyone from Canberra?)
