Best GRE Prep Books 2021

Person holding a toppling stack of the best GRE prep books - image by Magoosh

Here at Magoosh, I’ve reviewed all the best GRE prep books over the years. Today, I’m happy to announce that I’ve made some updates to our Best GRE Books List! While not all of these books are from this year (some are far from it), this GRE resource offers my honest book reviews and recommendations for the best GRE book options on the market. My goal is to keep you from sorting through the nimiety (that’s excess…a good GRE word) of bad GRE books out there so you can meet your graduate school goals.


 

Table of Contents


 

What makes a good GRE prep book?

What makes a good GRE prep book may seem subjective, but there are actually some pretty solid criteria we can use to rate each one with relative objectively. Here’s how we evaluated the GRE study guides out there!

  • Depth and quality of review material: Good test prep books will have in-depth overviews of the material you need to know for the GRE general test. This includes both content areas (e.g. number properties, statistics) and question formats (e.g. sentence equivalence, reading comprehension, word problems). However, longer isn’t always better: you want a book that will cover the material you’ll see on the GRE—and only that material! Extraneous explanations won’t help and could overwhelm you, making prepping for the GRE all the harder.
  • Quality of practice GRE problems: Trust us, you don’t get to be a master of quantitative comparisons, text completion questions, the analytical writing section, or…well, really any part of the GRE unless you’ve worked with test-like materials. This means that the questions should test material you’ll see on the real GRE, be formatted using GRE standards, and be of a similar difficulty level to the official exam.
  • Clarity and thoroughness of explanations: You could be working with the best-written GRE questions in the world and it wouldn’t matter if you don’t understand exactly why each correct answer is correct. As a general rule of thumb, longer, more detailed answer explanations are better—with the caveat that they should also be really clear. Ideally, they’d break down why each incorrect answer choice is wrong, as well as why the correct answer is right.
  • Number and quality of practice tests: It’s really hard to show up to the GRE exam and do well if you haven’t had practice taking lots of high-quality practice tests. Great GRE test prep books will give you at least one, and preferably more, tests with thorough answers and in-depth explanations.

Best GRE Prep Books 2020-2021

What do you need to know about the GRE test in 2021? In terms of prep, there have been some changes, mainly from ETS (the test-maker). In addition to two free, computer-based GRE practice tests you can take, called PowerPrep, the test-maker offers two additional GRE practice tests called PowerPrep PLUS. Getting realistic test-taking practice is vital, and these can be great tools to help you prep for a top score—I’ll talk a little more about how in my best GRE prep book reviews below.

Now that I’ve revealed my top picks, I’ll give you my honest reviews and tell you why each of these eight books made the list. I’ll give you the pros and cons of each text, and suggest who might want to consider purchasing each book (and who can skip it).

A couple of notes before we continue:

  1. Under most reviews, clicking on each book cover will take you to Amazon.com, which generally has the lowest prices. Please note that the prices listed are subject to change. The particular prices given here are in US dollars and reflect the price of a new edition (unless otherwise noted) in December 2020. You can almost always buy a used version at a discount.
  2. Some of the books listed here are not the newest editions. Most publishers change very little content from one edition to the other. If I can save you money by recommending an old edition of a great book, then I’m going to do that!

Time for the good stuff!

2. ETS’s The Official Guide to the GRE Revised General Test, 3rd Edition

ETS Official Guide-best GRE books-magoosh

This is the holy grail of prep. If you can only buy one book, this is it. The tone of voice may not be as friendly as the other books on the market. But if you can bear the dry content, you are getting by far the best practice since ETS writes the questions for the test.

Throw in four GRE practice tests, and the best GRE book on the market gets even better.

Here’s the full Magoosh book review: ETS Official Guide to the GRE Revised General Test 3rd Edition Book Review

3. ETS’s Official GRE Verbal Reasoning Practice Questions & Official GRE Quantitative Reasoning Practice Questions

gre book reviews magoosh
This one’s a twofer. ETS first published these two books in 2014, and boy are we glad they did (they’ve been updated for 2020). The Verbal book contains tons of new, official GRE verbal reasoning questions, written by the makers of the GRE. The strategies are nothing new (you can learn all of those from this blog), but this book is a must-buy, if only for the quality of its practice questions. The Quantitative Reasoning book, on the other hand, contains both helpful practice problems and useful new strategies for quantitative reasoning questions. A word of warning: these new math problems are really challenging. They’ll definitely require some extra attention, but will help you up your quant game.

4. PowerPrep and PowerPrep PLUS

PowerPrep PLUS - rated as one of Magoosh's best GRE prep books

By this point, you’ve probably noticed that ETS has a lot of products to help you prepare for the GRE. And they’re all excellent.

This is great news if you have a lot of time and money to spend before the test! Of course, if you don’t, it starts to get a little confusing (and to make it more confusing, ETS has repurposed some old tests! For all the info on this, check out Magoosh’s PowerPrep article).

Let’s clarify a couple things. First, there are two PowerPreps: the free version (just “PowerPrep”) and the paid versions (“PowerPrep PLUS,” two tests that cost $39.95 each).

No matter what, it’s a good idea to take at least one, and preferably both, of the free PowerPrep tests before your official exam. You’ll get to work with the computer format, and you’ll see questions straight from the test-makers.

If you have time, the PowerPrep PLUS tests do provide great practice—the explanations are a little brief, though it can be good practice to work out the processes on your own—but at a price. If you buy both of these exams, you’re basically paying half of what it costs to take the official GRE.

At the end of the day, it can be tricky to find great GRE practice tests, so if you’re preparing over a long period of time, buying at least one PowerPrep PLUS test is a good idea. But if you have a month or less before test day? You probably don’t need to make the investment.

5. Barron’s 6 GRE Practice Tests

This book is not perfect, even in its third edition, but in terms of sheer content, it is better than the Barron’s general GRE guide. Check out our review of the book here. Everything I wrote about the first edition of Barron’s GRE is still true in both the second and third editions. Bottom line: the questions are solid, but the difficulty is a little off (the questions are on average a little less tricky than the real thing), so it’s better to use this book as a question bank for extra practice, rather than as a source of balanced practice tests.

6. Manhattan Math & Verbal Strategies Set

Manhattan Prep materials are our most recommended after those from ETS and our own, and these books live up to the reputation. The question quality is high, and while the explanations are on the lighter side (similar to other Manhattan products), the book is still a good value. Purchase of this bundle unlocks Manhattan’s six online practice tests as well.

Diving into the specifics, the math is solid. The lesson sections are perfect for students who have some hazy memory of the topics and need explanations and examples, but they would not be sufficient for students who need to learn from scratch. Verbal is similar. The question difficulty range is solid, and the explanations are a little light.

This bundle is an updated, streamlined version of the Manhattan Prep GRE Set of 8 Strategy Guides. Those are still great resources! Check out our full review of that series: Manhattan GRE Series.

Kaplan’s GRE Prep Plus 2021

GRE Prep Plus 2021 Kaplan book

A lot of test-takers will be familiar with Kaplan’s ACT and SAT courses, which can be uneven. But drop your preconceptions, because Kaplan’s GRE Prep Plus 2021 is actually pretty solid.

In terms of the content, the Verbal sections give great test-taking and content strategies, and include high-quality, medium to hard practice questions. They’re not as great as some of the others on this list, but they will be useful for introducing you to GRE-style questions (watch out, though, as some of the reading passages are unrealistically long). Another plus? It doesn’t focus too much on GRE vocabulary memorization; instead, it primarily helps you with vocabulary acquisition strategies. In Math, the content review is solid if you’ve seen the concepts before, and the practice gives you good experience with different difficulty levels.

Finally, there are lots of useful bonus features to this book. It gives a strong overview of strategies for both the computer and paper GRE exams. There’s a handy reference section about admissions. The “Plus” version also gives you access to extra online tests.

8. Free GRE eBooks

Magoosh Free GRE eBooks-best GRE books-magoosh

Okay, they are not really books since unless you print them, you can’t physically hold them and flip through the pages (though an iPad can add a high degree of verisimilitude to the experience). Tangible or not, the eBooks are free and they provide a wealth of helpful strategies. Along with the rest of Magoosh’s free GRE resources, they are a great way to start your GRE journey, before deciding on which book to purchase. Download them from this page: Magoosh GRE eBooks. While you’re at it, check out these other free GRE study materials!

GRE Book Honorable Mentions


 

1. Vibrant’s GRE Analytical Writing: Solutions to Real Essay Topics Books

The Vibrant AWA series is a good resource. Not because they’re perfect, but because they contain GRE sample essays—something few books have. They’ll help you craft a decent response to a range of GRE essay topics (that’s if you can ignore the formatting issues that occasionally occur here. Again, these books are not perfect).

The main yellow book has 145 example essays. The other three (labeled Books 1, 2, and 3) are that same content, just split into three books. Their explanations are a little robotic and clinical, but they are thorough and clear. Some sample essays seemed a little more complex than they needed to be, but they would still be good for practice.

Vibrant breaks down pre-writing steps well with plenty of examples of how to break down a topic. One area where these books could improve is to give more information about scoring, including examples of essays that would receive other scores than a 6. (See Magoosh AWA Samples for sample essays responding to the same prompt that received different scores, including explanations for why they got the score they did.) Still, this book would be helpful to students who struggle with writing or are not comfortable writing in academic English.

Not required reading, but definitely helpful if you want to improve your essay score.

2. Manhattan 5 lb. Book of GRE Practice Problems

This book is actually quite good in many respects. And in fact, the publisher of this book is so good that we recommend using Manhattan materials in many of the Magoosh GRE study schedules. So why does this very large collection of Manhattan GRE practice problems only get honorable mention?

The truth is that this book’s Verbal practice problems have a number of problems. Unfortunately, the Verbal questions for Manhattan GRE are weak and not as GRE-like as they should be. Some light Verbal practice from this book may help you get familiar with the basic question types and formats. However, relying heavily on this book for Verbal practice will leave you ill-prepared for the real exam. ETS’s actual GRE Verbal problems are different from the ones in the Manhattan 5 lb. Book, in countless subtle-but-important ways.

Math, on the other hand, is where this book really shines. The Math problems are spot-on to the real test. All the math questions are very well designed, aptly capturing the tone, look, feel, and range of the real GRE Math section. The answer explanations are a little light, but sufficient. Given that the Quant half of this book is solid, think of the Manhattan 5 lb. Book as a Manhattan 2.5 lb. book for the purposes of your GRE prep.

For more info, see our review of the previous edition of the Manhattan GRE 5 lb. Book of GRE Practice Problems.

3. The Princeton Review, GRE Prep, 2021 Edition

I somewhat like the Princeton Review books for their big-picture strategies. These strategies are mostly absent from the Official Guide (though we share similar strategies in the Magoosh GRE eBook and on the blog). The content are a little generic and could apply to most standardized tests rather than the GRE specifically. However, if you are feeling lost with test prep in general and could use some review of basic skills like interpreting questions and using process of elimination, this could be a helpful resource. There are many different editions of Princeton Review books with slightly different amounts of content and prices, which gives you some flexibility about which one to go for.

Note: the “premium” version of this book has two extra practice tests.

GRE Books to Avoid

There are certain GRE books that seem very accessible, in the sense that they come from major publishers, but that should be avoided. The GRE Prep and GRE Prep Plus books also have issues with their questions that are both too complex and too simple at the same time. Another to avoid is McGraw Hill’s New GRE with 8 Practice Tests. The questions are too problematic to be useful, so we recommend using one of the books from our list instead.

Best GRE Prep Books FAQ

Are old GRE books still helpful?

The short answer? Some of them are! The reviews above flag editions that haven’t changed much in recent years. When it comes to them, don’t hesitate to get a used book if it hasn’t been written in.

The longer answer? If they were published after 2011, then they probably are at least somewhat useful. The last significant change to the GRE happened in August of 2011. Before that, the scoring system changed, as did the way the test adapts its difficulty level.

What this means for you is that if you have a friend or sibling who took the test last year, using their (unmarked!) books is probably fine. If you have your mom’s books from 1975, it’s well worth the investment to get new materials.

What are some of the best free online resources available for GRE preparation?
