Query: Just failed the CX-310-200

If you use this book as your primary study guide, expect to fail the exam. I used this book, on line training from Sun, and the Transcender test prep for this exam. I just took the exam and came away with a score of 50%. I've taken 10 other certification exams in my technical career (passing all of them on the first attempt) and this is the first one that I have failed.
