A good supplement and source of practice problems, although I found most of the questions to bee too easy.
To study for the GMAT I recommend using the Princeton Review book, the GMAC Official guide, this book, the GMAC quant review, and the Kaplan Comprehensive book.
a ton of great problems and that's about it. Sadly, there is some cross over with the main gmat book and if you take the gmat prep tests, you'll see a ton of these problems there as well. Still, these are actual questions so there is a lot of value in them.
Good starting book. Very good to discovery GMAC's thinking patterns, because others materials can deviate a lot depending on the topic! This is a must-read! Bests, Cesar
