Best GMAT Prep Books (2025): The Official Guide & Beyond
The Golden Rule of GMAT Books
You need the Official Guide.
There is no debate here. The GMAT Official Guide 2024-2025 (Focus Edition) is the only source of real retired GMAT questions. Every other book contains “simulated” questions written by test prep companies. While some are good, none are perfect.
Your strategy should be:
- Learn Concepts: Use third-party books (Manhattan Prep, PowerScore) to learn the math and logic.
- Practice: Use the Official Guide to test yourself on real questions.
Top Picks at a Glance

|---|---|---|
| Must Have | GMAT Official Guide 2024-2025 | Real Practice Questions |

1. The Must-Have: GMAT Official Guide (Focus Edition)
Verdict: Mandatory.
This bundle usually includes the main Official Guide plus separate books for Quant, Verbal, and Data Insights.
- Why: It contains 800+ real questions from past exams.
- How to Use: Do NOT use this to learn how to do the problems. The explanations are notoriously bad (often just “A is wrong because it is wrong”). Use it purely as a question bank to test your skills after you’ve learned the concepts elsewhere.
2. Best Comprehensive Set: Manhattan Prep “All the GMAT”
Verdict: The gold standard for strategy.
Manhattan Prep has updated their famous 10-book set into a streamlined “All the GMAT” bundle (All the Quant + All the Verbal).
- Why: They explain the “why” behind the math. They teach you shortcuts, estimation techniques, and how to think like a test-maker.
- Focus Edition Note: Make sure you buy the edition updated for the Focus exam (Geometry removed, Data Insights added).
3. Best for Critical Reasoning: PowerScore GMAT Critical Reasoning Bible
Verdict: The legendary “Bible” for logic.
If you are struggling with Critical Reasoning (Strengthen, Weaken, Assumption questions), this book is the answer.
- Why: It breaks down every argument type into a logical formula. It teaches you to see the “matrix” behind the question.
- Pro Tip: It is dense. Give yourself 2 weeks just to get through this book.
4. Best for Data Insights: The Official Guide Data Insights Review
Verdict: The only reliable source for DI.
Because Data Insights is a new section, third-party companies are still catching up. The official GMAC book is currently the best resource for this specific section.
- Why: It covers all 5 types: Data Sufficiency, Multi-Source Reasoning, Table Analysis, Graphics Interpretation, and Two-Part Analysis.

If you are self-studying, buy this stack:
- Manhattan Prep “All the GMAT” (for learning).

Total Cost: ~$150. Value: Priceless compared to a $1,500 course.
