【前言】 How to Use This Book
This book provides important information about the Quantitative Reasoning measure of the GRE® General Test, including the knowledge and skills that are assessed and the types of questions that appear. The book will help you:
• Familiarize yourself with the test format and test question types
• Learn valuable test-taking strategies for each question type
• Review the math topics you need to know for the test
• Check your progress with Quantitative Reasoning practice questions
The following four-step program has been designed to help you make the best use of this book.
STEP 1 Learn About the GRE Quantitative Reasoning Measure
Chapter 1 of this book provides an overview of the GRE Quantitative Reasoning measure. Read this chapter to learn about the number of questions, time limits, and the test design features. You will also find valuable test-taking strategies from ETS and important information about how the measure is scored.
STEP 2 Study the Different GRE Quantitative Reasoning Question Types
Chapter 2 of this book describes the types of questions you will encounter in the Quantitative Reasoning measure. You will learn what the questions are designed to measure, and you will get tips for answering each question type. You will also see samples of each question type, with helpful explanations.
STEP 3 Practice Answering GRE Quantitative Reasoning Questions
Chapters 3, 4, 5, and 6 contain sets of authentic Quantitative Reasoning practice questions in the content areas of Arithmetic, Algebra, Geometry, and Data Analysis, respectively. Answer the questions in each set, and then read through the explanations to see which questions you found most challenging. Look for patterns. Did specific content areas give you trouble? You can refresh your math skills in these areas with the GRE Math Review in Appendix A. The
GRE Math Review is a review of the math topics that are likely to appear on the Quantitative Reasoning measure. Each section of the GRE Math Review ends with exercises that will help you see how well you have mastered the material. Note that Appendix B provides information about the mathematical conventions that are used on the Quantitative Reasoning measure.
Prior to answering the practice questions, it might be helpful to review these conventions.
STEP 4 Test Yourself With the Mixed Practice Sets
Once you have completed the practice sets for each content area in Chapters 3–6, it is time to practice with authentic GRE questions in the Mixed Practice Sets in Chapter 7. Each Mixed Practice Set includes the question types and content areas contained in an actual Quantitative Reasoning section of the GRE General Test.
