Query: Almost useless for the exam!

I took and passed the 70-221 exam yesterday despite buying this book. There is very little technical information here and if you have passed the the core exams on Professional, Server, Network Admin, and Active Directory, then you already know more than they tell you here. Secret to success is a good test prep simulation like Transcender. The forms and information collection methodology presented here could be useful in a real design perhaps but have little or nothing to do with what is on the test.
