Eh. You can only cover so much. Most of my knowledge came from going to a ton of places with my parents while I was growing up, watching a shit ton of the history and discovery channels, playing historically themed video games, and listening to audio books in the car with my parents (back when they were on casset :D). We did at least touch on various parts of the world in history, but it was very very basic. Really though, there is a reason that people can have Doctoral Degrees in a single decade of history revolving around a single subject in a single location. There is a lot of history and various interpretations and sources of evidence that have to be examined. Trying to shove it all into a few years of highschool is insanity. I was going to be in AP geography in high school, but the teacher got arrested for possession of child porn and they couldn't find a replacement. I had done a ton of work that we were assigned over the summer, so I still got a bit out of it, but it was a disappointment.
