GMAT Official Guide Quantitative Review 2023-2024, Focus Edition: Includes Book + Online Question Bank + Digital Flashcards + Mobile App

I’m a Harvard grad, 99% GMAT scorer, and professional tutor/coach since 2002. I have taken the GMAT 6 times—including the GMAT online—with personal bests of 770 composite, 50/51 Quant, 48/51 Verbal, 8/8 IR (2 times) and 6.0 AWA (4 times), and I have scored 700+ on every attempt. More importantly, however, I’ve coached hundreds of aspiring business school students to significantly better GMAT scores over the last two decades, including scores as high as 720 (94%), 740 (97%), 760 (99%), 770, 780, and yes, even the elusive perfect 800, with an average score improvement of over 120 points. The GMAT Official Guide 2023-2024 Quantitative Review aka "OG Quant” (currently $21) receives my five-star recommendation because it provides a great source of over 950 real GMAT practice questions: 800 questions in the book, and an additional 150 questions via the mobile app. It also includes access to an online / mobile version of all the questions in the book, known as the GMAT Official Guide Online Question Bank. More importantly, however, this book is the only guide that specifically prepares students for the newer, one-hour shorter GMAT Focus Quantitative section starting at the end of 2023. So, is this book, which includes over 150 additional GMAT Quantitative / Problem Solving questions, necessary for a full GMAT preparation? No, probably not. There are already hundreds of practice questions available in the main official guide. However, this guide would be a good choice for someone who has already exhausted all the Quant questions in the 2023-2024 OG. So, what exactly has changed about the GMAT Focus? Well, a lot. The essay (AWA) is gone. Sentence Corrections, gone. Geometry, gone. And the Integrated Reasoning section—now called “Data Insights”—is adaptive like the rest of the exam, and includes the Data Sufficiency (DS) questions that used to be featured on the Quantitative section, meaning that Problem Solving questions are all that remain on the GMAT Focus Quant section. The GMAT Focus is over one hour shorter than the "classic" GMAT, and you can even go back and change up to 3 answers per section. Composite (total) scores will range from 205-805, and section scores on Verbal, Quantitative and Data Insights (V, Q, DI) will range from 60-90. Score percentiles have also shifted significantly, indicating that a GMAT Focus score of 645/805 is roughly equivalent to a score of 700/800 on the classic GMAT, for example. A dedicated GMAT self-studier should also utilize the free GMAT Club website, which has forum-style explanations to every GMAT question, because the official explanations in the OG are notoriously lacking. Simply google the first few words of any GMAT question, and a GMAT Club page will likely emerge as one of the first results. Although the GMAT is of course a computer test, and for this reason it is essential to take full, official practice tests on a computer, it can still be quite helpful to study and prepare on paper using a physical book such as this one. The OG is by far the very best source of GMAT practice questions, especially for Verbal—where real questions are indispensable—but you will often benefit from another type of study aid to help improve your scores: a book, a class, an online self-study program, a private tutor, or a combination of those 4 methods, in addition to self-study. In many cases, GMAT self-study using is possible—especially given the many free, public, and quality learning resources such as GMAT Club for Quant, but preparing on one’s own can be more daunting on Verbal, where the official explanations can be even more confusing than the questions themselves, and the online preparation options are far more limited and lacking.

Bons exercícios e explicação para os gabaritos. Porém, a parte prática é um pouco limitada. Recomendo para quem quer treinar exercícios de lógica, probabilidade e álgebra, todos em inglês. O livro não contém conteúdo de geometria. Também, possui conteúdo on-line, com suporte, mais exercícios e simulados.
