Let me help you with your purchase of this book…DO NOT purchase the “Official Certification guide”. This book has more grammatical errors than a second grade research paper which leaves you feeling stumped when you read it. There are a plethora of mistakes that have yet to be recognized by the publisher despite my many emails to them about said erors. The “Foundations Guide” is very similar and with a little effort in learning you can pass the CCDA with that book.
