The incredibly broad topic base of a geometry class makes full-length practice tests like this one, especially ones that include a number of open response questions, invaluable.  Here the class can really get that hands-on experience wrestling with the open-ended response problems, along with spiraling in old and rusty concepts. Whether it's given as a whole in a test-prep setting, or broken up into concept-based lessons or warm-ups, these extensive problems do a great job of helping keep your material focused and aligned with assessment.
