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.
