I agree with Julia G. DBQ prompt is, honestly, up in the air (I mean, last years was about cricket, who knows what they have in store for us). For the others, I would say 1914 - present is highly likely simply because a question about that time period hasn't been asked for several years, and there is a lot of information to discuss, mainly on the revolutions of the Middle East, China, and Russia. Silk Road and Columbian Exchange are out because they were on last year's. The Princeton Review 2013 Study Book also focuses on changes and continuities of women after each time period. I am thinking that is their way of saying the roles of women is a good possibility. I have seen one post somewhere that was pretty confident that we should know how to compare/contrast two different economic thoughts, know African trade routes, and know about Indian Ocean trade.
