Surprisingly difficult. I know all the countries and can solve the map quiz easily but i have a very hard time figuring these ones out. I wonder if it has something to do with the fact that I am not a native speaker and in my language C is used much less.
There seems to be two different forms of remembrance. Myself I know every country in the world by position on the map and location among other nations, but I am pretty poor at remembering countries alphabetically (all the countries beginning with P for instance) and these quizzes looking for a certain letter within their names I find even trickier.
