We know that Hogwarts starts taking on students at age eleven, and a lot of other European schools do too, but the other night I got to wondering. Do all schools in the world start students at age eleven?mIt doesn't seem very likely. We know that Muggle schools all over the world have different ages when they start school. South Korean children don't begin primary school until they're eight!
I'm just asking, do you think this is a possibility, and would it differ for different countries and continents?
