Query: The quintessential review for the GMAT

The book is the place to go if you want to get ahead with your GMAT. The Math review was particularly helpful in brushing up mathematical concepts and relationships. The numerous questions slowly develop a feel for the exam and with it, more confidence. I suggest getting the book and the software (which comes separately). I used the book to review concepts and go through the questions slowly, this built answering strategies. I then used the software to simulate exam conditions which built speed and accuracy. It was the perfect combination. I had the book for one week before the exam and still managed to walk in to the exam confidently and walk out with an above average score. Good Luck!
