TABLE OF CONTENTS

This book will help you prepare for the two math sections of the SAT: the no-calculator section and the calculator section. Your combined raw score from both these sections is converted to a scaled score of between 200800.

Start by becoming familiar with the structure of the two math sections. Then work your way through the chapters of this book and do as many of the practice sets as you have time for between now and test day. Be sure to review the explanations carefully. (Review them even for questions you got right, to make sure your calculations and reasoning are sound.) As your test date approaches, take the Math Practice Test found at the end of this book. Do this in a quiet environment and use the indicated timing guidelines. Again, be sure to review the explanations, found at the end of each chapter, to reinforce what youve learned.

The SAT Math Test

The SAT Math Test is broken down into a calculator section and a no-calculator section. Questions across the sections consist of multiple-choice questions and student-produced responses (Grid-ins).

The SAT Math Test is divided into four content areas: Heart of Algebra, Problem Solving and Data Analysis, Passport to Advanced Math, and Additional Topics in Math.

A few math questions might look like something youd expect to see on a science or history test. These crossover questions are designed to test your ability to use math in real-world scenarios. There are a total of 18 crossover questions that will contribute to subscores that span multiple tests. Nine of the questions will contribute to the Analysis in Science subscore, and 9 will contribute to the Analysis in History/Social Studies subscore.

Elimination and Guessing

Note that there is no penalty for guessing on the SAT, so it is in your best interest to answer every question. Ideally, taking a strategic guess means eliminating one or more choices and guessing from the rest to boost your chances of getting the question correct. However, if you are pressed for time, taking a guess on a potentially time-consuming questioneven without eliminating any of the choicescan help you get to more questions and get more points out of a section.

A Note about Grid-lns

You will see an occasional question without answer choices throughout the Math chapters of this book, starting in the next chapter. On the SAT, several of these Grid-in questions appear at the end of each Math section. Instead of bubbling in a letter, youll enter your responses to these questions into a grid that looks like this:

If you are gridding a value that doesnt take up the whole grid, such as 50, you can enter it anywhere in the grid as long as the digits are consecutive; it doesnt matter which column you start in. Gridding mixed numbers and decimals requires some care. Anything to the left of the fraction bar will be read as the numerator of a fraction, so you must grid mixed numbers as improper fractions. For instance, say you want to grid the mixed fraction 512. If you enter 51/2 into the grid, your answer will be read as 512. Instead, enter your response as 11/2, which will be read (correctly) as 112.. Alternatively, you could grid this answer as 5.5.

A repeating decimal can either be rounded or truncated, but it must be entered to as many decimal places as possible. This means it must fill the entire grid. For example, you can grid 16 as .166 or .167, but not as .16 or .17.
