This set of more than 400 flash cards offers both review and practice for the AP Calculus exams. The cards include formulas, definitions, theorems, derivatives, integrals, differential equations, and more for both Calculus AB and Calculus BC topics. Concepts on the front of each card are defined and explained on the reverse side. Additional exam practice comes from 100 sample problems, with solutions on the reverse side. The 4 1/2" x 2 3/4" cards have a punch-hole in one corner that accommodates an enclosed metal key-ring-style card holder, allowing students to arrange the flash cards in any sequence that suits their study needs. Here is a valuable study aid, whether used alone or in tandem with Barron’s AP Calculus exam review book. BONUS! An exclusive online exam included with the purchase of the flash cards.
