Here in the US, schools kinda touch on most countries but no one ever remembers them because most people don't care. The majority of them retain the 50 states, and the general location of the major countries of the world (Japan, China, Russia, and the UK among others). They also tend to know about Mexico and Canada since we kinda border them. But when it comes to smaller countries and things like the Canadian provinces, our school systems stop caring.
Yeah, it's all relevant to your nation basically.
It was more important for us to learn our western European neighbours, our former major territories and the big important nations.
No worth to knowing the American states, or the regions of France, or even our own counties.
