He read the second half of "Western Civilization: A Brief History" by Perry. watched The Teaching Company Foundations of Western Civ 2 DVD's, used REA Western Civilization II CLEP prep book and Peterson's practice test. Since he's still in high school, we treated this as a semester long course. Going a bit off topic, my oldest son chose to take Western Civ while he was attending John Brown University. Preston Jones, the author of the REA CLEP books was his professor. This was the first time my son ever hated a class. He liked Professor Jones but the class was real killer.
