Which book is right for me? Self-Study Guides and Exam Certification Guides are intended to complement one another. Though they will cover similar content, they do so in a very different manner. Choosing one book over another depends where you are in the study cycle. If you are familiar with the base concepts, but need to assess your knowledge and review/practice for the exam, we recommend the Exam Certification Guides. If you are new to a topic area and need more detailed discussions of the foundation concepts, we recommend you start with the Self-Study Guides.
