AP Narratives World History Review

The AP Narratives World History Review Game provides you with over 100 unique questions with the same style and difficulty level that you'll find on the AP World Test. They are broken up by skill (context, for example) and period. At the end of each level you can see what you got right and even access complete explanations. The first three sets are free but there are also two bonus packs with 40 questions each ($1 each).
