The SAT math book that you've been waiting for.
The game-changing 1600.io Orange Book establishes a new category of premium SAT-oriented instructional materials. This groundbreaking text is not a collection of "tricks" or "hacks" for getting around the SAT's function of assessing students' high school math skills. Rather, it meets the test on its own terms by providing comprehensive, clear, and patient education in every mathematical concept that can appear on the exam according to the officially published specifications for the test.
We crafted this two-volume set with a fanatical and obsessive attention to every detail, no matter how small, and we poured into it everything we've learned about how to most effectively help each student acquire the firm, confident grasp of math they need to become a confident master of the material — and, therefore, of the math sections of the SAT.
A #1 Bestseller, recognized as the new leader in its category
The BEST SAT Math Book on the Market (★★★★★)
I have had private tutors and other math books but they just do not compare. My favorite part is the video explanations....George explains each problem so well without making you feel dumb for getting it wrong....the way he solves these problems is so easy to comprehend that after a while you will find yourself looking at a problem with that same mindset. Also, in the back of Volume II, there is a spreadsheet with every single released SAT...The spreadsheet outlines what section every single question correlates to which is so helpful for knowledge gaps. I would recommend 1600.io to every single person I could. No matter your score aspirations whether they be an 1100 or 1550, the 1600.io team will help you achieve it and support you the entire way.
Perfect 800 SAT Math Score; these books are EXCELLENT (★★★★★)
As an Academic Counselor and College/Career Opportunity Advisor it is imperative that I provide reliable resources to our students. I ordered the 1600.io Orange Books to assist my 11th grader with her upcoming exam. After using the books and 1600.io website videos, my daughter took the March 2021 SAT and received a perfect math score on her first attempt....After working with a number of other students, I am convinced these books are an excellent addition to our test prep courses. I now recommend these books to all of my students and parents.
Lauded by influencers in the field
From the moment the Orange Book landed in the hands of readers, it garnered unprecedented accolades from all quarters, including tutors, parents, and, of course, students. The review shown here is from the SAT coach with more posts than any other on the r/Sat subreddit, and he has years of experience with test-preparation resources.
Every topic, clearly explained
To ensure that the instruction in this book covers every topic and technique necessary to master the math sections of the SAT, our team spent two years analyzing every math problem on every released test to ensure that we provided engaging, cogent, and thorough explanations for all of the needed concepts.
We've got problems...
...and our problems are going to be your problems. More than 16 tests' worth of meticulously constructed SAT-style example and practice problems with hundreds of fully-worked-out solutions (and alternative solutions), plus a complete answer key with each chapter.
A 1600.io invention: SkillDrills™
Sure, there are over 900 SAT-style practice problems. But many problem-solving techniques are composed of essential building block skills. Rather than forcing students to make the leap right from instruction to tackling test problems, we provide the intermediate step of these innovative mini-problem sets that build essential skills — and students' confidence.
Instant topic lookup
for released SAT problems...
If you're like most students, you're using released SATs for practice and self-assessment, so we've built a two-way bridge between reviewing the math problems you struggled with and the premier SAT math instruction book (hint, hint). Every one of the 1,566 math problems on the tests has been cross-referenced with the section of the book where the relevant primary math skill is fully explained, so students are supported for the entire learning cycle, from initial education, to practice and assessment, to pinpoint repair of skill deficiencies.
This outgrowth of our intensive problem analysis gives students the flexibility to use the book both "forwards" — learning the topics, then taking practice tests — or "backwards," whereby students can review their practice tests by looking up the problems with which they struggled and getting right to the relevant topic explanation in the book.
...and instant problem lookup from every math topic
In addition to supplying readers with over 900 problems of our own creation, we've included curated lists of the problems from all 26 released SATs, placed right in the topic and sub-topic section of the book where the primary solving skills for those problems are explained, and we've called out the most famous (infamous?) of those problems by inducting them into the 1600.io SAT Problem Hall of Fame.
This innovative feature lets students learn a skill, perform the exercises in the book, and then try their hand at some related real test problems to ensure that the lessons are being absorbed (with the help of our legendary explanatory videos, of course).
This is just one of the myriad ways that we put ourselves in the place of the student when designing the structure and content of this text, because we know that students striving to improve themselves are best served with empathy, not sympathy.
The Ultimate in Practice Problem Explanations:
1600.io Videos
The Orange Book is comprehensive, but it does not stand alone. We've brought it to life by making available our famous explanatory videos in a companion resource at 1600.io, wherein every chapter and section in the book has a corresponding set of videos for every single practice problem and SkillDrill along with an interactive answer sheet that lets students test themselves on problem sets from the book; these on-screen forms not only automatically score the student, but they also provides direct links to the relevant videos so students can instantly watch George explain the problems they had trouble with.
Students can subscribe to the Orange Book video explanations on an a-la-carte basis for $9 per month, or they can enroll in an All-Access membership for just $19 per month or $99 per year and gain access to every online resource we offer. And if you already have an All-Access membership plan at 1600.io, we have some good news for you: we already gave you access to the entire SAT Math Orange Book video explanation resource at no additional cost. When we say All-Access, we're not kidding around.
It's not just a book; it's part of an educational ecosystem.
Multiple solutions empower students
Test-takers learn that they often have alternatives, so if one approach isn't working out, there are others. This awareness reduces stress and increases confidence. Our clear, patient explanations are provided every step of the way.
1600.io first discovered "wormholes"
...and we literally wrote the book (well, the chapter) on them. We help students identify and productively exploit these expedited routes to solutions, saving them time and reducing errors.
Expert commentary elevates examples
We go beyond just explaining the steps as we develop a solution; we add illuminating notes and insightful guidance based on our years of successfully enlightening students of all levels about mathematical concepts and methods

From Chapter 0 to 21, the Orange Book gets into every crevice of the needed math
We not only made sure to include every topic and sub-topic that's every been tested on the SAT, we got into the nitty-gritty on all of them. Nothing is glossed over, no detail was too small to include, and every step-by-step example problem explanation moves through the solution in thoroughly explained fine-grained increments so that students are never left wondering, "wait — what did they just do?" We hate that, so we made sure you never have to experience it when using this book.
We've left it all on the page
This text is truly complete. It cuts no corners and assumes only the most basic mathematical knowledge. From Chapter 0, Foundations, to Chapter 21, Wormholes, we leave no stone unturned in our exploration of every relevant high school math topic as it related to the test, with carefully-paced descriptions of all the key principles required to attain total mastery of the material.
Student-centric structure
Each chapter is dedicated to one major concept. Within each chapter are sections and sub-sections, with fully-worked-out example problems and appropriate SkillDrills presented along the way as the principles are explained, ensuring that students are building the fundamental techniques that are needed for taking on test-style problems.
Starting from zero? We've got you
For the struggling student, the book has everything they need at a level of detail that lets them work through topics comfortably without stress, starting with Chapter 0, which lays down the fundamentals. Every concept and solution step is clearly explained and principles are not just given once, but are repeated as required to ensure that students never get lost along the way.
Almost there? Ace it!
For the more advanced student, we've provided concise statements of key points along with a complete summary at the end of each topic chapter, so refreshing those math skills is easy. Need more depth on just one or two topics? Dive into the chapters for all the detail you can handle. And we don't just throw formulas at you; the basis of all principles is clearly articulated, with demonstrations and proofs provided for the edification of the curious student.
Perfectly paced practice
At the end of each section within each chapter, there's a set of practice problems that apply to that section, and at the end of each chapter, there is an extensive set of practice problems that require the application of skills discussed throughout the chapter, so students have ample practice material for reinforcing concepts and enhancing their problem-solving proficiency.
Big AND expensive!
We don't do compromise when it comes to the quality of the materials we craft for our amazing students, and as a result, this text is well over 800 pages and thus requires two volumes. A work with this degree of thoroughness incurs a cost, yet it is a relative bargain, with a significantly lower per-page cost than other SAT books. So it's actually big yet inexpensive on a dollar/page basis (see Chapter 12, "Ratios, Probability, and Proportions").
