An excellent book. Using this and its companion, MCSE The Core Exams in a Nutshell, as my primary study resouces I managed to pass each exam first time and completed all six in three weeks.

I have tried other books/courses, but this was the best resource (and the cheapest). It will help you to pass, but in my opinion is more than a cramming aid.

Make sure you read the errata and do not get tripped up by minor errors.

I would recommend this to anyone.
