 * This document contains either a study guide OR pairs of exams taken from the same exam bank:
 * If two exams have the same s-number, then v1 and v2 have the same questions, presented in different (random) order.
 * Exams with different s-numbers have different questions and may not have the same difficulty.
 * Click items in the table of contents and appropriate page should be reached. This feature should allow you to print only those pages that you need.
