When I was little in school we had to learn all the continents, countries, capitals of countries, political maps, seas, rivers around the world, today they don't teach any of this.
Geography and history do not matter, the educational system is disastrous.
I could easily name somewhere between 50 - 100 countries, and have been able to since the 5th grade (could probably name more then than now). The problem is, its just not a skill you need for anything, unless you want to be a participant on Jeopardy some day.
