Kaplan has prepared students to take standardized tests for more than 50 years. Our team of researchers know more about preparation for the GRE than ayone else, and youll find their accumulated knowledge and experience throughout this book. The GRE is a standardized test, and so, every test covers the same content in roughly the same way. This is good news for you; it means that the best way to prepare is to focus on the sort of questions you are likely to see on Test Day. The main focus of this book is on strategic reviews, exercises, and practice tests with explanations that will help you brush up on any math skills you may have forgotten. If possible, work through this book a little at a time over the course of several weeks. There is a lot of math to absorb, and it's hard to do it all at once.
