Negative Positive
Title: One can do without book. But it is easier with it.
Review: One buys the book because there' s very little stuff like that on the market (excercises, sample questions, sample quizes). They were, probably, the first to come up with that kind of material. Yes, it is superoverpriced, yes, it is way too simple compared to the real thing. But where do you get your gas if there is only one gas pump available? I bought it. I can not honestly say it did not help me to pass the written CCIE test. It did.
Is the review positive or negative?
