Mike Meyers' A+ Guide to Operating Systems

Summary: What is what?
Review: I am almost finished with this book and cannot tell when I am learning what Mike Meyers thinks is important, and when I am learning something pertinent to the OS exam. Also, the Q&A at the end of each chapter provide no answer keys.

I passed the hardware exam and was confident that I would. I already had sufficient hardware experience. I am extremely unsure that this book will prepare me for the OS exam. Definitely not what I expected.
