The GMAT has three scored sections: Quantitative Reasoning, Verbal Reasoning, and Data Insights. Each requires a different kind of preparation. The right study material depends on where you are starting from, how much time you have, and which sections are holding your score back.
This guide covers everything you need: the official GMAT books and what each one is actually for, the best third-party books by section, free resources worth using, and a phased prep plan that ties it all together. All resources listed are fully updated for the current GMAT format.

The most important thing to understand about GMAT preparation is the difference between official and unofficial material. Official questions are written by GMAC, the same organisation that writes the actual exam. They test the exact thinking patterns and logical structures the GMAT rewards. Unofficial questions, even from reputable publishers, do not fully replicate it.
This distinction matters most for practice. Use official questions to simulate the actual test and calibrate your score. Use third-party books to learn concepts and strategies. Mix them in the wrong order and you either practise before you are ready or study concepts without ever testing whether they work on real questions.
GMAT Official Guide Bundle 2025-2026
The Official Guide Bundle is the foundation of any GMAT preparation plan. Published by GMAC, it contains over 1,800 real GMAT questions along with access to the Online Question Bank, a digital platform where you can create custom practice sets by question type, difficulty, and section. The 2025-2026 bundle consists of four books:
| Book | What it contains | Best used for |
|---|---|---|
| GMAT Official Guide 2025-26 | Main guide covering all three sections, 900+ questions, concept overview | Primary reference; covers all question types |
| Quantitative Review 2025-26 | 150+ additional Quant questions with detailed explanations | Extra Quant practice after exhausting the main guide |
| Verbal Review 2025-26 | 200+ additional Verbal questions: Reading Comprehension and Critical Reasoning | Extra Verbal practice; strong on CR explanations |
| Data Insights Review 2025-26 | Additional DI questions across all five question types | Targeted practice for the section most test takers under-prepare |
The bundle (~$110) is the most cost-effective way to access all four books and the online question bank. If budget is a constraint, start with the main Official Guide (~$40-50) and add section-specific books only where you need more practice.
The explanations in the Official Guide are answer-focused rather than strategy-focused. They tell you why a specific answer is correct, not the general approach to that question type. Pairing it with a dedicated strategy book or course makes preparation more effective for most test takers.
GMAT Official Practice Exams (Free + Paid)
GMAC offers two free full-length adaptive practice tests through the GMAT Official Starter Kit, available at mba.com. These are the single most important free resource available to any GMAT test taker. The tests are fully adaptive, use real retired GMAT questions, and score you on the same 205-805 scale as the actual exam.
Two additional paid exam sets (Official Practice Exams 3-4 and 5-6) are available for purchase if you need more full-length simulation after exhausting the free ones. Use at least one full-length official mock early in your preparation to get a diagnostic baseline and at least one in the final two weeks to simulate test-day conditions.
GMAT Strategy Books Worth Having
The Official Guide gives you real questions. It does not give you deep strategy instruction. These books fill that gap. They are written by independent authors and are not affiliated with Crackverbal. We recommend them because they are genuinely useful for specific preparation needs.
Free GMAT Study Material Worth Using
There is a reasonable amount of high-quality free GMAT material available. The key is knowing which free resources are genuinely representative of the exam and which are not.
| Resource | What it includes | Best for |
|---|---|---|
| GMAT Official Starter Kit Free | 2 full-length adaptive practice tests + sample questions from GMAC | Baseline diagnostic; most accurate free simulation available |
| mba.com question bank Free | Sample questions across all three sections and all question types | Familiarising yourself with question formats before buying the OG |
| GMAT Club forums Free | Thousands of real GMAT questions with community and expert explanations | High-difficulty question practice; especially useful for 700+ targets |
| Crackverbal GMAT Video Library Free | Concept-level video explanations across Quant, Verbal, and Data Insights | Learning strategies for specific question types; good supplement to OG |
| Crackverbal GMAT E-books Free | Section-specific written guides developed by Crackverbal faculty | Structured concept review, particularly for Indian test takers |
| Crackverbal Free Practice Test Free | Full-length GMAT practice test with performance analysis | Early diagnostic and identifying weak sections before building a plan |
The two free official practice tests from GMAC should be treated as test days, not casual practice. Take them under full exam conditions: timed, no interruptions, starting fresh. That is the only way to get an accurate score. The free section-level questions on mba.com are useful for familiarisation but are too few to build meaningful practice volume.

Access Free GMAT ResourcesHow to Use GMAT Study Material: A Phased Plan
The most common mistake in GMAT preparation is treating all material as interchangeable, working through books in publication order rather than in the order that actually builds competence. Here is a framework that works regardless of your timeline.
Choosing the Right Material for Your Timeline
| Timeline | Recommended material stack | What to skip |
|---|---|---|
| 3 months or more | Official Guide Bundle + Crackverbal course or e-books (section-specific) + all 4-6 official practice tests | Nothing. This is the full preparation. |
| 6-8 weeks | Main Official Guide + one section-specific third-party book for your weakest area + 2 official practice tests | Section review books (save for a retake if needed) |
| 3-4 weeks | Main Official Guide only + 2 free official practice tests | Additional prep courses. There is not enough time to absorb them properly. |
| Retake preparation | Official Score Report analysis first to identify exact weak areas, then targeted section review book(s) + Official Practice Exams 3-6 | Repeating material you already know. That is inefficient use of retake time. |
The most important variable is not how much material you use but how deeply you work with what you do use. Test takers who work through the Official Guide twice, reviewing every error carefully, typically outperform those who rush through three or four books without reviewing their mistakes.

Frequently Asked Questions
What is the best GMAT study material for the GMAT?
The GMAT Official Guide Bundle 2025-2026 is the most important resource for any GMAT preparation. It contains over 1,800 real GMAT questions, access to the Online Question Bank, and is the only source of authentic retired GMAT questions. Pair it with Crackverbal’s video library and e-books for strategy instruction across all three sections, and work with a mentor if you want personalised guidance on where to focus.
Is the GMAT Official Guide enough to score 700+?
The Official Guide provides the right practice questions but limited strategic instruction. Its explanations tell you why a specific answer is correct, not the general approach you should take to that question type. Most test takers targeting 700+ benefit from pairing the Official Guide with a dedicated strategy book. The Manhattan Prep series covers Quant and DI; the PowerScore CR Bible is the most thorough standalone resource for Critical Reasoning. Crackverbal’s video library and e-books cover the same ground if you prefer a guided online format. The Official Guide alone can be sufficient for test takers who are already strong test-takers and primarily need familiarity with GMAT-specific formats.
What free GMAT study material is available?
The most valuable free resources are the two official GMAT practice tests available through the GMAT Official Starter Kit on mba.com. These are the most accurate free simulation of the actual exam. Crackverbal also offers a free video library, e-books, and a free practice test developed specifically for the GMAT. GMAT Club’s forum contains thousands of official and community-sourced questions with detailed explanations, and is especially useful for high-difficulty practice targeting 700+.
How many practice tests should I take before the GMAT?
A minimum of four full-length practice tests is recommended: one diagnostic at the start of preparation, two or three during the final 4-6 weeks of preparation, and one 3-4 days before the exam. GMAC offers two free official tests and four additional paid tests (Official Practice Exams 3-6). The most important variable is not the number of tests but the quality of review after each one. Spend as long reviewing as you spent taking it, with a clear categorisation of every error.
Can I use old GMAT books to prepare for the GMAT?
Older GMAT books should be used with caution. The Classic GMAT was retired on January 31, 2024. Books written for the Classic GMAT include content that is no longer on the exam: specifically Sentence Correction, Analytical Writing Assessment, and the old Integrated Reasoning format. The Quantitative and verbal concept reviews in older books are still largely applicable, but any section-level guidance, timing advice, or score strategy needs to be updated for the current GMAT format. When in doubt, use the most recent Official Guide edition, which is fully aligned with the current exam.
