I've thought about using cwh exclusively, but I have a couple reservations. First, if I follow vol. 3 we will repeat some things that we have already covered recently, and we also won't get to American history until next year. Second it seems like it's very western centric, where Biblioplan covers WORLD history. Finally, she only has the first 3rd of the vol. 4 out right now, so what do we do when we finish vol. 3? She also said that vol. 4 ends at the civil war, which means there will be 5+ volumes and we can only get through history 2.5 times instead of 3x. That's a little nitpicky I know, but it means we won't touch on American history, government, and whatnot in high school unless I change curriculum again.
I'm not trying to be argumentative. I've been wrestling with these things here at home, (and driving my husband nuts), and haven't found a happy medium.
