Barron's AP Chemistry Flash Cards

Chemistry definitions, formulas, and structures are presented in question form on 500 separate flash cards, with explanations and chemical reactions indicated on the reverse side. This boxed set of 4 1/2" x 2 3/4" flash cards is designed with a punch hole in one corner of each card. The hole will accommodate a metal key-ring-style card holder enclosed with the cards. Using the holder, students can arrange the flash cards for their Q and A sessions in any sequence that suits their needs--perhaps by general topic, or alternately by leaving out cards with questions and answers that test takers already know well.
