The book aims at preparing readers for the OCA Exam, but it's not a pure prep guide. We cover the objectives of the exam with discussion; that's about it. The rest is really designed by what I think a beginner should know about the language and how to use it to good effect. There are, for example, several techniques I think a beginner should be exposed to that the OCA exam considers an advanced skill. I want to make sure the reader gets a feel for how the language is used -- or, at least, how I use it in my own work -- so they're not just learning the bare minimum required to pass the exam.
