This book is a pile of pants!. The main problem is that it feels 'all over the place', shifting from 1 subject to another, and then goes back later. If your revision style is to write structured study notes, then forget it, my notes ended up all confused and muddled, pretty much like the book. The author tries to follow the Microsoft exam syllabus to the letter, in his chapter layout. You could put the syllabus and contents page side by side and no notice the difference. I personally do no think that this is the best way to layout a study guide, and in this case it doesn't work. Add to this the numerous mistakes, in fact at one point, the first main chapter on MTS, the first MTS structure diagram which is fundamental to the rest of the chapter is in fact incorrect, it is a picture explaining how network printing works!!! I'm afraid this one is collecting dust on the shelf, and I am now using the Exam Cram books. Get them and save some money too!
