Ever since I failed my 70-291 test, I've supplemented all my certification studies with these shortened Exam Cram books. They always provide a great summary of what I've learned the 3 weeks or so I spend studying more detailed guides.
This one SEEMED a bit longer than the others, but there is alot of material for this test. Either way, I was able to read it in about a week (just 1 chapter each day, less than an hour), and it really explained things much clearer than MS books. The difficult concepts from the material fully sunk in, and I felt twice as confident for the test - which I aced with an 826.
I've also used the Exam Crams for the 70-291 and 70-293, but this just clearly has been the best so far. It reads very smooth - the author has a natural way with words, and turns simplicity into an art form.
I wish I could give a more detailed review of where it helped me most, but it's been a few weeks now and I'm on to my next test. On the positive, I don't remember any errors - spelling or technical. The study guide I'm reading now has already had a handful of errors in just 5 chapters!
After this book, I am giving much more consideration to using the full Exam Cram study guides for my tests! Bravo to Que - books of this quality should just boost their reputation into outer space.
My thoughts - HIGHLY RECOMMEND!
