The Network+ Exam Guide is strictly exam-related and flows with minimal interruption. Key Concepts are the only "notes" set apart from the text by special formatting. Visual cues are used liberally throughout the book, with diagrams expressing concepts in a form that aids comprehension and memorization. The Quick Study bonus booklet aids retention before, during and after each chapter is read. Practice test questions, with explanations of both correct and incorrect answers, follow each chapter. A Self-Assessment test and answer key help you gauge your learning progress. The Exam Guide also provides addresses for on-line help and supplemental sample tests, testing locations, test-taking tips and strategies, and emotional preparation.
