There is a great phone app called World Geography Quiz that will quiz you on flags, country shapes, capitals, and all the rest. It has a staged entry thing where you get access to more categories and regions as you play. I'm not affiliated with it or anything, just thought of it when I saw this because it's become a real go-to geo quiz fix for me.
