In the GMAT Advantage they give a variety of useful strategies, then show you how to solve almost every problem by a common sense method. The questions in the book are similar to those in the GMAT Official Guide so I know my review is on the mark. One thing: Why doesn't the GMAT Official Guide offer multiple strategies and understandable shortcuts?
I'm only half through with my review (scheduled to take the GMAT in May) but already I'm starting to feel comfortable with the math.
The data sufficiency stuff on the exam is weird. Who came up with this kind of question? The best help for these questions are on the GMAT Advantage CD ROM. You just have to do a bunch of these to really understand them. The CD ROM categorizes these by certain characteristics which is extremely helpful. Then the author provides a specific strategy for each different question.
The interactive tutorials are great. I keep referring back to them. They gave me the basics (which I had forgotten) in a very imaginative way-each problem is "graded" as to difficulty to help you understand why you are missing certain types of questions. And there are more challenging, interactive exercises.
I'm looking forward to getting over the exam hurdle. Thanks GMAT Advantage.
Throughout the book, the graphics of this old professor, the quotes, and the humor made me, well, almost enjoy the review.
The strategies for the verbal critical reasoning questions allowed me to see inside the test makers mind. Very helpful. Also the insights for the verbal sentence correction grammar questions were the best help for me as my grammar skills needed help. I'm pretty strong in math so I usually worked the problems that were marked most difficult. This saved me a lot of time.
You have to work hard with this book but it was worth it. Thanks. Great review for the money.
