Ooh, fun! I got:
111 out of 111 for Europe.
87 out of 87 for Asia.
133 out of 162 for Africa. Eegh, West Africa... :P
35 out of 39 on South America... Damned Suriname/Guyana/French Guiana always screw me up. At least I got Paraguay/Uruguay right this time...
22 out of 24 for Australia.
37 out of 42 for Central America.
87 out of 87 on Middle East.
141 out of 150 for... the USA. Yeah. Back to second grade for me...
35 out of 39 for Canada... Ugh.
Not even going to bother with Oceana and the Carribean. Or China, because I already know I'll get at least half of that wrong.
