1600.io SAT Math Orange Book Volume II: Every SAT Math Topic, Patiently Explained

[NOTE: This is Volume II of a two-volume set; each volume must be purchased separately.]

Setting the new standard: The SAT Math book that you've been waiting for.

The game-changing 1600.io "Orange Book" establishes a new category of premium SAT instructional materials. This groundbreaking text is not a collection of "tricks" or "hacks" for getting around the SAT's function of assessing students' skills. Instead, 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.

Unprecedentedly rich and comprehensive, this text has 850 pages, 22 chapters, over 900 practice problems broken down into 95 unique categories, more than 200 example problems with multiple written solutions, over 600 SkillDrill™ mini-problems, available video explanations to 1,350 SkillDrill and practice problems, and an innovative appendix that links all 1,508 SAT problems across 26 released practice tests to their corresponding topic explanations in the book.

• Every SAT math topic, clearly explained
  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.
• A 1600.io invention: SkillDrills™
  Many problem-solving techniques are composed of building block skills, so 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
  Every one of the 1,508 math problems on the released SATs has been cross-referenced with the topic section where the primary math skill is fully explained, so students are supported for the entire learning cycle.

Each volume in the series contains chapters which have section problems, chapter problems, SkillDrills, answer keys, and lists of related real problems from released tests.
