The 11 Best ACT Prep Books for 2026 (By Section & Score Goals)

Taking the ACT is an essential part of the college admissions process for many students. 

While a good ACT score or even a perfect score won’t make or break your application by itself, it’s an important metric that can help you stand out. So if you’re taking the ACT this year, chances are you’re looking for the best resources to help you work towards your goal score.

In this post, we’ll go through the best prep books for specific goals and the best resources overall. You can also keep our step-by-step guide to preparing for the ACT on hand as you make your study plan and set your goal score with the help of our score calculator.

By the way, we don’t get a commission if you buy any of these books – our assessment is based on more than two decades of experience as ACT tutors, not affiliations with any test prep companies or publishers.

How to Choose the Right ACT Prep Book

Not all ACT prep books solve the same problems. Some are stronger in one particular section of the SAT. Some focus more on test content, others on test strategy. The “best” option depends on where your personal strengths and weaknesses lie, what your score goals are, and what kind of explanation actually works for you.

Instead of “Which book is best?,” the real question is: “Which book works for me for my specific goals and needs?”

The Best ACT Prep Books in 2026

Best ACT Prep Book Overall: The Official ACT Prep Guide

Best for: Comprehensive coverage of everything on the ACT and full-length practice exams

Price: $39.95 (or $89.95 if purchased as a set with the four official subject guides, including for the optional Science section)

If you could only use one book to prepare for the ACT, this is the one we would recommend. Because it’s made by the same folks who make the real ACT, the practice questions in this guide are the most reliable and realistic ones you’ll find.

The book also includes more practice tests than you’ll find in any other resource we reviewed. As well as 6 full-length practice tests on paper, the book gives you access to three more online for a total of 9 full-length practice tests. (The ACT test makers also offer one practice test for free online, which you can find here.)

As well as the extra online practice tests, the book also gives you access to digital additional study materials, including an online practice question bank with 100 additional practice questions per ACT subject area.

Another advantage to this prep guide is its detailed answer explanations, including explanations for what mistake you might have made based on each incorrect answer choice.

While the test makers advertise that the book offers key test-taking strategies, some students have reported that they needed other resources to help them with strategy.

The ACT guide offers tips on how to approach different types of questions, but the advice tends to be pretty basic, like inserting your answer back into the sentence for complete-the-sentence questions. That’s good advice if you haven’t heard it before, but it’s not exactly a high-level test-taking strategy.

In short, this is the best comprehensive guide to the ACT and the best place to get your full-length practice exams, but if you want to focus on key test-taking strategies, you may want to supplement it with an additional resource.

This is for you if:

  • You want comprehensive ACT review for every section of the test

What we like:

  • Most reliable resource directly from the test makers
  • Largest collection of full-length practice exams
  • Comprehensive answer explanations that help you understand and learn from your mistakes

What we don’t like:

  • Limited focus on test-taking strategies

Best of the Rest for Overall ACT Prep

Looking for other prep options that cover the whole test? The best resources we found were Barron’s ACT Study Guide and, for those looking for more key test-taking strategies, the ACT Prep Black Book.

Barron’s ACT Study Guide

Best for: Additional comprehensive test content review

Price: $36.99

A lot of the major test-prep companies publish ACT study guides. Out of the main options out there, we found Barron’s the best for overall prep.

The book includes a diagnostic test and three more complete practice tests, plus two more tests online. There’s also a self-assessment and guidelines to help you make a study plan based on your performance level, goal score, and how much time you have until test day.

This book also contains more advice on test-taking strategy than many of its competitors. Since that’s one area where the official guide from the ACT makers falls short, this book could be a good option for students who want more guidance on how to approach each question type.

Some students have said that they found the Barron’s practice test questions harder than the questions from the official practice tests. That’s better than the other way around (which is a criticism we’ve heard about the Princeton Review’s prep book), but it’s still not ideal.

You could get discouraged by making more mistakes than you would on the official tests, and you could lose valuable time by studying questions that you don’t actually need to know.

That’s why, for an estimate of how you’ll score on the real ACT, you should always go off official practice tests. Third-party resources are great for extra practice, but they’ll never be as realistic as materials from the test makers themselves. 

This is for you if:

  • You’re looking for additional general ACT prep beyond the official prep book, especially on test-taking strategy

This may not be for you if:

  • You mainly want extra practice tests

What we like:

  • Offers six full-length practice tests
  • Gives practical advice on making a study plan
  • Questions are generally a realistic representation of the real test

What we don’t like:

  • Some students report that the questions are harder than the official ACT questions

The ACT Prep Black Book

Best for: Key test-taking strategies and understanding the typical question formats and patterns on the ACT

Price: $34.99

Like any standardized test, the ACT uses predictable question formats and typical answer choice misdirects. Getting familiar with those patterns will help you avoid falling into common traps and help you understand what each question type is looking for.

That’s what the ACT Prep Black Book is designed for. Instead of reviewing the concepts that are being tested on the ACT, it focuses on how they’re being tested. That includes typical phrasing of questions, answer choice traps to watch out for, and how to approach each section of the test. The book goes through official ACT practice questions as examples.

If you’re feeling fairly confident on the actual content of the ACT and want to learn concrete strategies to approach the test more effectively, then this is the best book we can recommend. Especially because of the time pressure on the ACT, having strategies to fall back on can help you pick up extra points even if you’re a strong student.

Remember that strategy will only get you so far if you have gaps in understanding the actual material on the test. If you’re feeling shaky on the concepts themselves, then we’d strongly recommend combining the Black Book with another book for content review.

This is for you if:

  • You want to learn test-taking strategies for the ACT

This may not be for you if:

  • You need to review concepts and test content before getting started on strategy

What we like:

  • Clear, concise language
  • Useful strategies that work for students in all score ranges

What we don’t like:

  • Does not include content review, only test-taking strategies
  • Because it uses real, official practice questions as examples, it’s best to use this book after you’ve taken some of the official practice tests

The Best ACT Prep Books by Section

Depending on where your strengths and weaknesses lie, you might want to focus on specific sections of the ACT in your review. Here are the best prep books we found for each section of the test.

Best for the ACT Reading Section: Erica Meltzer’s Complete Guide to ACT Reading

Price: $31

This book gives students a deep dive into the reading section of the ACT. It goes through each of the most important question types, including detailed explanations of the right and wrong answers. There are also two unofficial practice tests for the reading section.

The book strikes a good balance of content review and test-taking strategy, so it can be helpful to students who need a review of the concepts as well as those who are more interested in learning how to approach the test efficiently.

A lot of students have noted that the book is written in a very straightforward, dry style. Many students might like that – after all, you’re probably reading it to learn how to get a higher ACT score, not for fun in your free time – but for others, it might be a little boring.

One drawback of Meltzer’s book, for some students, is that it’s best suited to those who are in a higher score range. The book does a great job of drilling down into the details of the ACT reading section, but if you’re not aiming for a top score, then it might be more information than you need. You know best what your strengths and weaknesses are and what target score you’d be happy with, so when you’re using this guide for your ACT prep, you can decide what level of detail is right for you.

This is for you if:

  • You want to work on either content or strategy

This may not be for you if:

  • You’re not aiming for a high score
  • You benefit from a more engaging writing style

What we like:

  • Balance of content and strategy
  • Straightforward, to-the-point writing style

What we don’t like:

  • Focus on more advanced concepts may not be right for students across all score ranges

Best for the ACT Science Section: The Master Key to ACT Science

Price: $28

Even though ACT Science is now optional, many students will still want to take the Science section. This prep book for the science section is one of the best we reviewed for question drills. It contains 20 practice drills and three realistic (though unofficial) practice test sections.

It also goes through the science sections of official ACT practice tests in detail, giving in-depth explanations for the answers. The book doesn’t spend much time on science concepts themselves. That may not be a problem, since, in our experience, you’ll only see 2-3 questions on ACT Science that really test your memory for scientific concepts.

The basic principle is that the ACT science section can be boiled down to a few basic, repeated patterns. Once you’ve mastered those patterns, you’ll be prepared for any ACT science question. That’s why the book emphasizes learning those typical question and answer formats over extensive content review.

One of the book’s biggest strengths is its time-management strategies. The ACT science section requires you to read passages of text, analyze them, and select the right answer choice in a very tight space of time: you only get 35 minutes to answer 40 questions. This book shares concrete strategies for how to save time on each question by reading more efficiently and eliminating answer choices more quickly.

Overall, this is the best book to help you with test-taking strategy and time management. If you’re looking for a deeper understanding of concepts, then you may need an additional resource.

This is for you if:

  • You want to learn time management strategies
  • You want access to realistic practice questions

This may not be for you if:

  • You choose not to take the optional Science section
  • You want to review concepts and not just strategy

What we like:

  • Practical strategies tailored to the ACT format
  • Six practice test sections

What we don’t like:

  • Formatting is somewhat cluttered and could be distracting
  • Doesn’t include much content review

Best for the ACT English Section: Erica Meltzer’s Complete Guide to ACT English

Price: $35.65

This guide goes through everything you need to know for the English section, including both content and strategy.

One of the best aspects of this book is its cumulative approach to content. A lot of prep books teach a concept, give you practice questions on that concept, and then move on. That’s not very realistic, since the real ACT will test multiple concepts at a time, all mixed together. But Meltzer’s book lets you practice concepts you learned previously along with newly introduced ones. (The only downside to that is that it makes it harder to work through the book out of order.)

Strategy can be especially helpful on the English section of the ACT, which is the most time-pressured of all the ACT sections: you’ll be asked to answer 75 questions in just 40 minutes! This book has useful tips to help you save time here and there, which can definitely add up across the whole section.

Like with Meltzer’s other books, some students complain that the book is written in an overly dry style, without visual distractions or a friendly tone. For some people, that’s a drawback; for others, it helps them focus on what they really need to know. You can decide what’s right for you and your learning style.

And, like with Meltzer’s ACT reading guide, there’s a lot of detail that you might not need to know if you’re not aiming for a top score or don’t have much time to prepare. If your goal score is less than 30, there will be parts of this book that you don’t need to pay as much attention to. But if you’re trying to raise your score into the top range, then you’ll find lots of useful material to help you do so.

This is for you if:

  • You want either content or strategy review
  • You want to work on your time management skills

This may not be for you if:

  • You benefit from a more engaging writing style
  • You’re not aiming for a top score and would feel overwhelmed by the extra detail

What we like:

  • Balance of content and strategy

What we don’t like:

  • Reuses some official practice questions
  • Might be overly detailed if your goal score is below 30

Best for the ACT Math Section: College Panda ACT Math 

Price: $32

This book is nothing if not thorough. It goes through every topic that you’ll need to know for ACT math (you can take a look at the table of contents here).

There are also 400 practice questions and detailed explanations of the answers. All the questions are original, so you don’t need to worry about doing an official practice question that you’ll later see again on a practice test.

Not all students will need to work through every section of the book, but if you have specific topics you need to review – or if you’re just starting out on your ACT prep – it’s a great resource for targeted study and practice.

Pure test-taking strategy is not the focus of this book. For that, we’d recommend a dedicated strategy guide. But for a review of any concept on the math section of the ACT, as well as extensive math questions drills, this is the best place to be.

This is for you if:

  • You want extensive review of every math topic on the ACT, including more original practice questions

This may not be for you if:

  • You want more focus on strategy

What we like:

  • Comprehensive content review for the math section
  • Uses only original practice questions

What we don’t like:

  • May include too much conceptual review for some students
  • Some students may want more strategy guidance

More Subject-Specific ACT Prep: The 4 Official ACT Subject Guides

Price: $21-24 each (or $89 for a full set of subject guides plus the Official ACT Prep Guide)

Among the overall test prep guides, our top recommendation was the official book from the ACT test makers.

The test makers also publish four subject-specific guides to the Reading, Science, English, and Math sections. So why aren’t these our top recommendations for section review?

One major drawback to these subject guides is that they repeat practice questions that are in the Official ACT Prep Guide. That means that if you work through the subject guides first and then do the official practice tests in the overall guide, you might be answering questions you’ve seen before – which could give you a skewed idea of what score range you’re hitting.

Not all of the practice questions are repeated – you’ll still gain access to a lot of new practice material compared to the official prep guide by itself. Each subject guide also gives you one year of access to the official ACT online question bank for more practice.

And these guides do include useful conceptual review for the topics you’ll encounter on the ACT. If you feel like you need to work on the underlying concepts for any given section of the test, then these can be a useful place to start.

They also include more test-taking strategies than the Official ACT Prep Guide (though still not as much as options like the ACT Prep Black Book.

So, will these subject guides benefit you? Maybe, if you need to work on conceptual review or if you already know that one ACT section is going to be more challenging for you, and you don’t mind redoing some official practice questions. But you may want to start with the Official ACT Prep Guide and then see if you need more review on a specific section of the test.

This is for you if:

  • You want conceptual review for a specific section of the SAT
  • You want more practice questions, including the official ACT online question bank

This may not be for you if:

  • You want to focus on strategy more than on conceptual review
  • You haven’t taken the official practice tests yet and don’t want to repeat those questions

What we like:

  • Books use official practice questions from the test makers

What we don’t like:

  • The books repeat questions that are in the official prep guide
