Query: good, but not great

This book distinguishes itself by concentrating on step-by-step walk-throughs of practical exercises. And while that is helpful, only a few questions in the test are simulations. Many of the exam questions are about esoteric details, which are not covered by this book.I purchased four books to study for the 70-431, and I would place this in the bottom two.
