-- Tutorial text is strictly exam-related and flows with minimal interruption.-- Key concepts are the only "notes" set apart from the text by special formatting.-- This series is designed to be used either with or without outside instruction. Study aids begin with the Chapter Opener which readies the reader for learning.-- Chapter Notes bonus booklet aids retention before, during and after each chapter is read.-- Chapter summaries reiterate important points and help readers draw conclusions about what they have learned.-- Chapter opener questions are repeated at chapters end with the answers.-- Practice test questions with explanation of both correct and incorrect answers follow each Chapter.-- To help the reader fully understand the topic, visual cues are used liberally throughout the book: 1) Diagrams put concepts into a visual form that aids comprehension and memorization, and 2) Figures confirm readers' understanding of procedures.-- A Self-Assessment test/answer key helps the reader gauge his learning progress. The answer key to the Self-Assessment test also lists the chapters where the topic of each question is discussed, to give the reader direction for review.-- Also provides additional information, such as addresses for on-line help and supplemental sample tests, testing locations, test-taking tips and strategies, and emotional preparation.
