Chemistry definitions, formulas, and structures, organized according to the College Board's six "big ideas" for AP Chemistry, are presented in question form on 500 separate flash cards, with explanations and chemical reactions indicated on the reverse side. The cards measure 4 1/2" x 2 3/4" and have a punch-hole in one corner that accommodates an enclosed metal key-ring-style card holder. The ring allows students to arrange the flash cards in any sequence that suits their study needs. Updated to reflect the brand new AP Chemistry exam that will be administered for the first time in May 2014, these cards are a valuable study aid, whether used alone or in tandem with<i> Barron's AP Chemistry</i> review book. <B>BONUS! An exclusive online exam included with the purchase of the flash cards.</B>
