How to learn the names of every country in one hour

I've tried before to learn the names of all the countries in the world and where they are located. I find it annoying to read an article about, say, Burkina Faso, and have no clear idea of where the country is located. Despite some efforts with flashcards, I never made much progress learning all the names of the Balkans, countries in Africa, countries in Oceania, and the former Soviet Republics.

Then recently I checked out a website that my son, a second-grader, was using in school to learn the names of the countries in Central and South America.  (Click on an area of the world, and then select the "Level 1 - Beginner" option.)

In less than an hour, I learned the names of every country in the world. (Here's lookin' at you, Narau.) This type of quiz that you can take quickly and repeatedly is an excellent way to learn certain types of content very efficiently.
