In the US they barely cover anything not American or European (and by American I mean USA, they barely cover American stuff from before the European settlers arrived). We learned a tiny amount of stuff in one of my classes but it was very little. I only learned about a lot of the rest of the world in my AP World History class, because it was part of the curriculum and because my teacher knew we learned almost exclusively about US and Europe, so he knew we needed catch up and could skim the European parts. But most students in the US don’t take AP World, it’s considered more advanced than a typical world history class (theoretically). I’ve forgotten a lot and obviously still wasn’t an expert on most of the world, it takes years to reach that. But I do know some about just about every major region, just not necessarily a lot. And it makes food more understandable because I have to wonder less about how an Asian ingredient made its way to Kenya or something
