Do you remember learning the U.S. state capitals in school when you were younger? I do. 50 states, 50 cities. And I had to know them all. School curriculum and standards are determined state by state, but most grade school lesson plans do include this essential element of American politics and geography. If you grew up in Kentucky or Massachusetts, maybe you memorized these cities in fourth grade. If you lived in Texas, it might have been in fifth. But generally, most American students can name the 50 state capitals by the time they graduate elementary school. So, now you're a grown-up. Do you remember them anymore? It might be harder than you think… Take the quiz below and test your skills.
