If you’re aiming for a 705+ GMAT score, you already know the stakes. A high score can put you in the running for top MBA programs, competitive scholarships, and even career opportunities post-graduation. But can you get there using just the GMAT 2025 Official Guide (OG)?
The OG is a must-have—it’s written by the test makers and features real GMAT questions. But here’s the catch: while it’s great for building fundamentals, it doesn’t go far enough for test-takers looking to break into the top percentile. The hardest GMAT questions—the ones that truly separate a 650 from a 750—are underrepresented, and the OG doesn’t dive deep into test-taking strategies or time management techniques.
So, is the GMAT OG 2025 enough? Short answer: No, but it’s an essential starting point. In this guide, we’ll break down what the OG does well, where it falls short, and how to build a study plan that takes you past 705.
The GMAT Official Guide: A Must-Have, But Not a One-Stop Solution
If you’re preparing for the GMAT, the Official Guide (OG) 2025 is likely the first book you’ll hear about—and for good reason. Published by the test makers themselves, it provides access to real, retired GMAT questions, making it an essential resource for anyone aiming to understand the test inside out.
The OG does a great job of covering fundamental concepts, helping you get comfortable with the question formats and difficulty levels you’ll encounter on test day. It’s particularly useful for building a strong foundation in Quantitative and Verbal reasoning, with detailed explanations straight from GMAC. But here’s the catch: if you’re aiming for a 705+ score, the OG alone won’t be enough.
While it includes a broad range of practice questions, the hardest, top-percentile questions are underrepresented. It also lacks deep strategy insights—the kind that can help you tackle tricky time management issues, advanced problem-solving techniques, or test-taking psychology.
So, where does the GMAT OG 2025 fit into your study plan? It’s your starting point, not your complete strategy. To break into the 705+ range, you’ll need targeted practice, strategic test-taking techniques, and additional resources that go beyond what the OG offers.
Breaking Down the GMAT OG 2025: What’s Inside?
The GMAT Official Guide 2025 is the closest you can get to the real exam before test day. Created by GMAC, the organization behind the GMAT, it features actual retired questions, making it an essential resource for anyone prepping for the test. But what exactly does it offer, and how can it help you reach your target score? Let’s break it down.
- Real GMAT Questions, Straight from the Source – With 900+ official questions, you get an authentic look at the test’s structure, format, and difficulty levels. Since these are pulled from past exams, they provide the most accurate practice available.
- Covers Every Tested Section – The OG 2025 includes practice for Quantitative Reasoning, Verbal Reasoning, and the new Data Insights section. While it’s great for core prep, keep in mind that it doesn’t include full-length practice tests or computer-adaptive testing.
- Customizable Online Practice – The digital question bank lets you create personalized practice sets, filter by difficulty, and track your progress, making it easier to focus on your weak spots.
- Clear, Step-by-Step Explanations – Every question comes with a detailed breakdown of the solution, helping you understand not just the right answer but the reasoning behind it.
- A Strong Starting Point – If you’re new to GMAT prep, the OG is an excellent way to build your foundation in math, grammar, and logical reasoning. It’s designed to help you get comfortable with the test, but for top scores, you’ll need to go beyond what’s in this book.
While the GMAT OG 2025 is an essential tool, is it enough to hit a 705+ score? That’s where things get tricky. Next, let’s look at its limitations and what you’ll need to do to go beyond the basics.
705+ on the GMAT? You’ll Need More Than Just the OG
The GMAT Official Guide 2025 is a must-have, but if you’re aiming for a 705+ score, you’ll need more than just this book. While the OG offers real GMAT questions and a solid foundation, it doesn’t fully prepare you for the hardest problems or the strategic thinking required to dominate the test.
Here’s the issue: most OG questions fall into the easy-to-medium range. If you’re looking to break into the top percentile, you’ll need exposure to more difficult, high-stakes problems—especially in Quant and Verbal. The toughest Data Sufficiency and Critical Reasoning questions, the kind that separate 600s from 700s, are underrepresented.
Beyond question difficulty, the OG lacks in-depth strategy. It tells you how to solve problems but doesn’t teach you efficient shortcuts, smart guessing techniques, or how to manage time under pressure. And since the GMAT is computer-adaptive, relying only on static questions won’t prepare you for the real test experience.
Bottom line? The OG is your starting point, but it’s not a complete roadmap to 705+. To get there, you’ll need high-level practice, adaptive mock exams, and advanced test-taking strategies. Up next, let’s explore how to supplement your prep for a top-tier score.
Cracking the GMAT 2025: What You Need Beyond the OG
Now that we’ve established why the GMAT Official Guide (OG) alone won’t get you to 705+, let’s talk about what will. To achieve a top score, you need a well-rounded approach that includes tougher practice questions, adaptive mock exams, and targeted strategy training. Here’s how to take your prep to the next level:
1. Challenge Yourself with Harder GMAT Questions
