Best GMAT® Study Materials and Resources for 2026

If you are putting together a study plan, you are probably wondering what materials to use.

The internet does not make this easy. There are hundreds of GMAT® prep books, dozens of online question banks, and more YouTube channels than anyone could watch in a lifetime. Some of it is great. Some of it is outdated. And some of it was never good to begin with.

So how do you sort through it?

Think about it like buying equipment for a sport. You need three things: something to teach you the technique, something to practice with, and something to simulate the real game. In GMAT® prep, that means instruction materials, practice questions, and full-length practice tests.

This post breaks down the best options in each category — what to use, what to skip, and how to put it all together.

If you are also deciding between a self-paced course, a live class, or a tutor, we have a separate guide that compares prep course options. This post is about the materials themselves.

Start with official materials

Before anything else, get familiar with what GMAC puts out. GMAC is the organization that writes the GMAT®. Their materials use real, retired GMAT® questions written by the same people who write the exam.

No third-party provider can fully replicate the way GMAC writes questions. Some come close on quant. On verbal, the gap tends to be wider. The reasoning patterns, the wrong-answer traps, the tone of the passages — these are hard to copy.

Think of it like training with the actual equipment you will use on game day. You can practice with a slightly different ball, but at some point you want to use the real one.

Official materials should be the center of your prep. Here is what is available.

The Official GMAT® Starter Kit (free)

Go to MBA.com and download the Official GMAT® Starter Kit. It is free. It includes two full-length practice exams and a set of practice questions across all three sections.

The two practice exams in the starter kit are the most accurate baseline you can get. If you have not taken a diagnostic test yet, this is where you start. We talk about why the baseline matters in our guide on how to start your GMAT® studies.

The practice questions in the starter kit are also useful for getting a feel for the question formats before you dive into a full study program.

Official GMAT® Practice Exams (paid)

GMAC sells additional official practice exams beyond the two free ones in the starter kit. These tend to be one of the best predictors of your actual score.

If you are working through a study plan, you will need multiple practice exams. Save at least two official exams for the final phase of your prep, when you are fine-tuning your score. The official scoring algorithm is more accurate than any third-party test.

The Official Guide to the GMAT®

The Official Guide — usually called "the OG" — is a book containing hundreds of real, retired GMAT® questions across all three sections. For most people, it is the most useful book you can buy for GMAT® prep.

The OG gives you exposure to the full range of question types and difficulty levels. Working through it — especially the verbal questions — is something most successful test-takers do.

A few tips for using the OG well:

Do not write in the book. Use a separate piece of paper. On the real exam, you will not be able to underline text or circle answer choices. You want your practice to match test conditions as closely as you can.

Do not blow through all the questions in the first two weeks. The OG is a finite resource. Once you have done all the questions, you will not get fresh ones. Pace yourself. A handful of questions per topic as you learn it, then save the rest for the practice test phase.

Re-solve questions regularly. Pick a small set of problems you have already done and work through them again as a warm-up each day. This builds pattern recognition and speed. The questions on the real exam will not be identical, but they tend to be similar in structure and logic.

Official GMAT® Verbal Review and Quantitative Review

GMAC publishes separate review books with additional official questions beyond what is in the main OG. If you work through the entire OG and want more official practice, these are worth getting.

The Verbal Review is especially valuable. Third-party verbal questions tend to miss the nuance of real GMAT® questions. Having more official verbal practice tends to be worth the cost.

The best prep books (beyond official materials)

Official materials are essential. But they are not a complete prep program on their own. The OG teaches you what the questions look like. It does not teach you the underlying concepts or strategies.

For content instruction, you need a prep book series or a course. We have a full comparison of prep courses that covers the landscape. If you prefer books over digital courses, here is what we recommend.

Manhattan Prep GMAT® Strategy Guides

If you want a print set that teaches you the "why" behind the questions — not just gives you problems to solve — Manhattan Prep tends to be the strongest option we have seen.

They cover the content you need for each section and provide strategic frameworks for approaching different question types.

They are not perfect. Some of the material has not been fully updated for the current GMAT® format. The exam dropped geometry and sentence correction a couple of years ago, and some books still include those chapters. But the core content — number properties, algebra, critical reasoning, reading comprehension — is strong.

If you go this route, buy the current editions and skip the chapters on topics that are no longer on the exam. Our complete topic list breaks down exactly what is and is not tested.

What about other book series?

Kaplan, Princeton Review, and Magoosh all publish GMAT® prep books. They range from decent to mediocre. None of them will teach you wrong information. But the depth and quality of instruction tends to be lower than Manhattan Prep.

If you already own one of these series and it is working for you, there is probably no need to switch. But if you are buying from scratch, Manhattan Prep is the print option we would point people to first.

Free GMAT® resources

You do not need to spend money to prepare for the GMAT®. It tends to take longer with free resources, but it can work.

Here are the best free resources we know of.

GMAT Club

GMAT Club (gmatclub.com) is the largest GMAT® forum on the internet. It has been around for over 20 years and has an enormous archive of questions, explanations, and discussion threads.

The best use of GMAT Club is for quant practice. The community-generated quant questions are often quite good, and the discussion threads can teach you approaches you will not find in a book.

For strategy advice, the incentives on forums are a little weird. The loudest advice is not always the best advice. People share what worked for them, which may or may not work for you. Take the strategies with a grain of salt and trust your own data — your practice test scores will tell you more than any forum thread.

YouTube

There is a lot of free GMAT® content on YouTube. Some of it is excellent. Most of it is average. And the platform does not filter quality for you — someone who is great at making videos is not necessarily great at teaching the GMAT®.

If you go the YouTube route, treat it like a self-paced video course. Find one or two channels that resonate with your learning style and follow their content sequentially. Jumping between ten different creators will give you a fragmented understanding.

Be skeptical of promises about specific timelines or score guarantees. If someone says you can go from 500 to 700 in two weeks, that is almost always a best-case scenario presented as typical.

Our podcast

We have a podcast that covers strategy, study methods, and tactical advice for the GMAT®. It is free and available on all major platforms. If you are looking for a structured audio resource that comes from someone who has been teaching this exam for close to a decade, it is a good option.

You can find it on our podcast page, or search for "The GMAT Strategy" on Spotify, Apple Podcasts, or YouTube.

Practice question sources

Practice questions are the fuel for your prep. Here is how to think about the different sources.

Official Guide questions

Real GMAT® questions, written by GMAC. Use them throughout your prep, but especially during the practice test phase.

GMAC official practice exams

The most realistic full-length tests available. Use them to track your progress and calibrate your score expectations. We have a full guide on how to review practice tests that will help you get the most out of each one.

Third-party question banks

TTP, Magoosh, and e-GMAT all have large question banks. These are useful for drilling specific topics during the knowledge building phase. They are less useful for simulating real exam conditions.

The main risk with third-party questions is that they can teach you patterns that do not appear on the real exam. This is especially true for verbal. If you spend months learning to answer one provider's critical reasoning questions, you may find that real GMAT® critical reasoning feels different.

Use third-party questions for content practice. Use official questions for test simulation.

GMAT Club quant questions

The community-generated quant questions on GMAT Club are a solid free option. They tend to be harder than the real exam, which can be good for pushing your ceiling. If you can do GMAT Club hard questions, you can probably handle the real exam. The reverse is not always true.

Tools and apps

A few tools that can support your prep.

Anki or any spaced repetition app

Spaced repetition is one of the most effective ways to memorize formulas, rules, and patterns. Anki is free and works on most devices. Create flashcards for anything you need to recall instantly: exponent rules, divisibility patterns, common idioms.

The key with flashcards is regular review. Making the cards is easy. Reviewing them daily is what makes them work.

A simple spreadsheet for tracking

You do not need a fancy app for this. A Google Sheet or a notebook works fine. Track three things:

What you studied each day. How many hours. What you got wrong and why.

That data becomes the basis for your review sessions and your study plan adjustments. Without it, you are guessing at what to focus on.

The GMAT® Official Starter Kit platform

The starter kit on MBA.com includes a question bank interface that lets you create custom practice sets by topic and difficulty. It is not as full-featured as a paid course, but for free practice with real questions, it is hard to beat.

What to avoid

A few categories of materials that tend to cause more harm than good.

Pre-2024 materials that have not been updated

The GMAT® changed significantly in 2024. Geometry was removed from quant. Sentence correction was removed from verbal. The old Analytical Writing Assessment was dropped. The exam was restructured into three 45-minute sections.

A lot of materials published before 2024 are still circulating. Some have been updated. Many have not. If you are using older materials, check what was removed from the exam and skip those sections. Our guide on what is on the GMAT® has the current topic list.

What happens if you skip this step? You spend weeks studying geometry or sentence correction. Then you show up on test day and neither appears. That is time you will not get back.

Outdated practice tests

GMAC's practice tests have been updated for the current format. But some third-party tests have not. If a practice test includes sentence correction or geometry, it is testing the old format. Your score on that test will not map cleanly to the current exam.

Shiny new AI tools (with a caveat)

There are a growing number of AI-powered GMAT® prep tools. Some are useful. Some are not. We have a full guide on using AI for GMAT® prep that covers what actually helps and what tends to waste time.

The short version: AI can be good for generating practice questions on specific topics, explaining concepts you are stuck on, and building study schedules. It is not good for simulating real GMAT® questions or predicting your score.

How to put it all together

The right set of materials depends on your budget, your timeline, and your learning style. Here is a simple framework.

If you are studying for free: Start with the Official Starter Kit on MBA.com. Use GMAT Club for additional quant practice. Find one or two YouTube channels and follow them. Use our podcast for strategy and motivation. Plan for a longer timeline — free prep tends to require more hours per point of improvement because you spend more time deciding what to do next.

If you can spend on books: Get the Official Guide and the Manhattan Prep Strategy Guides. Add the Official Verbal Review if you need more verbal practice. This gives you instruction plus a large bank of official questions.

If you want a structured course: Check our prep course comparison for recommendations based on your budget and learning style. A digital self-paced course gives you structure and progress tracking. A live class or tutor gives you even more guidance.

In every case, the foundation is the same. Official materials. Consistent practice. Regular review. And a study plan that gives you enough time to actually learn the material.

If you are not sure which materials fit your situation, or you want help figuring out where you stand and what to focus on next, you are welcome to book a complimentary Strategy Session. We will take a look at your situation and help you figure out the best path forward.

The materials matter. But how you use them matters more.

Frequently Asked Questions

What is the single best GMAT® study material?

For most people, the Official Guide to the GMAT®. It is the only resource that contains real, retired GMAT® questions written by GMAC. Most successful test-takers we have worked with have used it. If you can only buy one thing, the OG is the one to get.

Can I study for the GMAT® using only free resources?

Yes. The Official Starter Kit on MBA.com gives you two free practice exams and a question bank. GMAT Club has thousands of free practice questions. YouTube has free video lessons. The tradeoff is usually structure — you will spend more time deciding what to do next, and less time just executing. If you have a longer timeline and a tight budget, free resources can work.

Should I buy the Manhattan Prep books or a digital course?

It depends on your learning style. If you learn well from reading and prefer to work at your own pace, the Manhattan Prep books are a strong print option. If you learn better from video or want built-in structure and progress tracking, a digital course will serve you better. We compare the major course options in our prep course guide.

How many official practice tests should I take?

Most students do well with three to twelve official practice exams over the course of their prep, depending on how much improvement they need. Save at least two for the final phase of your preparation. The official exams use the real scoring algorithm, so they tend to be the most accurate predictor of your actual score. Our guide on how to review practice tests will help you get the most out of each one.

Are older GMAT® prep books still useful?

Partially. The quant and data sufficiency questions from pre-2024 books are still relevant. The reading comprehension and critical reasoning questions are still relevant. But you should skip any chapters on geometry or sentence correction, since those were removed from the current exam. If you are not sure what changed, our complete topic list breaks down what is and is not on the current GMAT®.

Should I use GMAT Club for strategy advice?

GMAT Club is excellent for quant practice and for connecting with other test-takers. For strategy, the advice on forums tends to reflect individual experiences rather than universal truths. Read the threads, learn from the community, but make decisions based on your own practice test data and what works for you.

How do I know if my study materials are working?

Track your practice test scores over time. If your scores are moving in the right direction, your materials and methods are working. If your score has not moved after 40 to 50 hours of study, the issue may be with your study method rather than the materials. Our post on breaking through a score plateau can help you diagnose what to change.

Want to learn even more?

If you are building a study plan from scratch, our guide on how to build a GMAT® study plan that works walks through the full timeline from diagnostic to test day.

If you are not sure how long your prep will take, our guide on how long to study for the GMAT® gives you a framework for estimating based on your starting score, target score, and weekly study hours.

And if you want to hear us talk through how to choose materials and build a study routine from the ground up, we have an episode of our podcast series that covers exactly that — how to start your GMAT® studies, what to look for in materials, and how to avoid the common mistakes that cost people weeks of wasted prep. You can find it on our podcast page, or search for "The GMAT Strategy" on Spotify, Apple Podcasts, or YouTube.
