The amount of information on which one can be tested (in any of the exams) is staggering. Often there's little rhyme or reason to the organization, naming and winemaking of different regions. That's where blank study maps come in. Not only do they offer another type of visual association for memorizing, there's a good chance you'll get at least one "Where precisely is appellation X?" type of question in an exam. Each map is listed with its key. I found it helpful to print the blank map on one side of a sheet and the key on the back. They can even be laminated for use with dry-erase markers. All are set for a standard 8.5x11 in page.
