A set of roughly 400 flash cards provide test takers with main points of Constitutional history, the branches and functions of the government, the political party system, lobbyists, the role of media in government, and a lot more. The cards measure 4 1/2″ x 2 3/4″ and have a punch-hole in one corner that incorporates an enclosed metal key-ring-style card holder. The hoop allows students to organize the flash cards in any sequence that suits their look at needs. A valuable look at aid, whether used on my own or in tandem with the newly published Barron’s AP US Government and Politics test prep manual. BONUS! An exclusive online exam included with the acquisition of the flash cards.
