Chemistry definitions, formulas, and structures, organized in line with the College Board’s six “big ideas” for AP Chemistry, are presented in question form on more than 500 separate flash cards, with explanations and chemical reactions indicated at the reverse side. 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 ring allows students to prepare the flash cards in any sequence that suits their study needs. Up to date to reflect the up to date AP Chemistry exam so as to be administered for the first time in Would possibly 2014, these cards are a valuable study aid, whether used on my own or in tandem with Barron’s AP Chemistry review book. BONUS! An exclusive online exam included with the acquisition of the flash cards.
