The A+ Certification & PC Repair Handbook (Charles River Media Networking/Security)

On the CD The following A+ Certification Review Questions are related to the general topics introduced in Part I, Chapters 1 through 4, of this book. The answers and supporting references are provided after the review questions. You will notice that all of the answer references specify chapters that are located in Part II of this book: The A+ Certification Exams. It is likely you will need to refer to these chapters in Part II to correctly answer the questions. The real A+ exams are not easy to pass unless you prepare yourself well. Likewise, these questions are not easy to answer unless you prepare yourself well by researching the material. When you finish this book, successfully complete the A+ practice exams located on the CD-ROM, and finally take the real exams, you will be glad you followed this proven format.
