Excellent work, which certainly contains some shells, but escalation and clarity not possible to advance step by step. The first tests put you in confidence while the latter are truly a challenge. The recall of knowledge at the beginning of the book and wants synthetic clear: it goes to the point and avoid unnecessary fragmentation as other works of the same type may know. I highly recommend this book allowed me, in 2 short months to get 310 points TAGE MAGE. If one can judge the quality of a work to the results it generates, so I can only recommend this book to those also preparing for this exam. If, like me, you are anxious not to get lost in the many books and records available or looking for efficiency, then this book is for you.
