The book had very little connection to the actual exam. The exam was a set of scenarios with questions afterward. The questions weren't that difficult, but many of the scenarios were too fuzzy, or the questions had fuzzy answers, with a "choose all that apply" format. This was not an objective test. Passing is largely a matter of luck. The predecessor to this exam (70-100) was much more objective.
And of course, Microsoft doesn't tell you your score at the end, only whether you pass, so you don't know how much more studying you have to do for next time. ...
I'm sure personal preference will cause both books to have a good readership, but wanted to add my 10 cents.
