1. The 2019-2020 Official ACT Prep Pack with 7-Full Practice Tests

You might’ve seen the Official ACT Prep Pack book being recommended a lot of times in the previous years. Nevertheless, this is one of the best in making you feel that you’re answering actual ACT questions from the earlier exams. Practice questions provided by Princeton Review or Kaplan could be beneficial; questions that could prepare you on the big day are a must.

Since it is best as a practice test book, it is not a comprehensive studying material. The concepts such as algebra on the math part or the mechanics and usage on the English part are not covered in this book. If you want to practice, you could consider this prep book.

This book is unofficially termed as the “Red Book.” There is also a supplementary “Black Book” for this, which will be reviewed later.

Nevertheless, you might need to buy an additional overall review guide if it’s your first time taking the test.

Although there are limitations, it’s still a good ACT prep book.

You would be more motivated to study harder because of the ideas offered by this book. The given strategies are more beneficial because it doesn’t focus on giving tricks.

This prep material also tackles the pressure, and stress students feel when they take the exam. Thus, it could help in boosting your confidence. Another difference it has with other traditional prep books is that it advises on how to avoid being frustrated and stressed during the exam.

The book provides tips on how to develop good habits of active reading rather than explaining how to answer the ACT reading section. Moreover, it treats reading, like having a conversation, and makes you focus on direction words.

You can review math thoroughly, but you would need to purchase a separate prep book for practice.

9. ACT ELITE 2020 by McGraw-Hill

Steven Dulan, the president and founder of Advantage Education, Inc, wrote the ACT Elite review book. Advantage Education provides live test preparation lectures in schools, colleges, and other faraway places. Therefore, many students have succeeded in taking different exams because of Dulan’s guidance.

You can find three practice tests and three more online when you get this prep book from McGraw-Hill. Every section also has additional practice questions to train and prepare you well on the big test day. Even though the publishers haven’t updated the length of the book’s English section, they’ve improved the questions for the said subject. Before, the questions focused too much on grammar. Now, the question distribution is more balanced.

The number of math questions for topics such as geometry, trigonometry, and algebra is ample for this book. Nevertheless, the most complex pre-algebra and elementary algebra questions are not. Also, the reading part is too difficult because the fiction passages have too many details rather than action and dialogue. For the non-fiction ones, they have an overwhelming amount of information.

The highlight of this book is its science section. The format of the essay is okay. You can also have more practice in probability and statistics. Although there are 50 test-day strategies, don’t expect a lot for the explanation of answers.

You can build your skills in math, English, reading, and science from the book’s practice materials. Throughout the chapter, you can learn good advice or strategy, but the information is presented confusingly. The book doesn’t include logarithm concepts. For psychology, there is less focus on learning theories and more on practicing.

ACT Prep Books Buying Guide: Things to Consider When Buying ACT Prep Books

The quality of the review material is the most important to consider when choosing your ACT prep book. There should be both practice questions and tests for your prep book of choice. Here are some factors you should consider when buying an ACT prep book:


When preparing for the test, you ought to know what subject or concepts you need to concentrate on to avoid wasting time mainly. Diagnostic tests for each subject could help you assess your knowledge and skills.

For instance, in algebra, you could get good scores in other related concepts but not on concepts about plane geometry. Once you start studying these, you could work more on questions about plane geometry.

Practice Questions

For the ACT, a useful prep book has hundreds or thousands of practice questions so that a student can study the material comprehensively. Nevertheless, the quantity of questions is not enough. The same level of difficulty and structure of the questions from the actual ACT is the best to practice on.

Practice Tests

Almost all available ACT prep books in the market have many practice tests. However, similar to the practice questions, they need to be close to the actual test to prepare them better. Also, practice tests need to be timed. This can help students identify their weak spots or the areas they need to work more on. As a result, their studying becomes more effective.

Subject Reviews

The ACT prep book of your choice should review every subject section on the test, such as math, reading, English, and science. Writing is optional. You can also opt for books that concentrate on a single subject. This is good if you’ve identified the areas you need more help.

Explanation of the Answers

When studying, you can’t just answer the practice questions without understanding the answers. Therefore, a good ACT prep book should give a solid explanation for an answer, and the other answer choices are incorrect. There’s a higher chance of choosing the right answer when you have the explanations in your mind.

Test-taking Tips and Strategies

Since the ACT is not the same as tests taken in high school, it is essential to get a book that gives tips and strategies on how to approach the actual test. Make sure that the book you choose has tips and strategies that are easy for you to understand.

Online Content

If you have a budget, you can get the more expensive ACT prep books to access extra content online, such as additional practice tests and quizzes. Some students also study concepts better online than from books. ACT Prep classes on PrepScholar are designed from the ground up.


ACT prep books are good for high school students because they are rather affordable. The price range is usually between $14 and $49. The more practice questions and tests a prep book has, the more expensive it is. Also, you can access more resources online.


Is the ACT and SAT the same?

Many universities and colleges consider ACT and SAT. Students have the choice to take one or both. Even though both exams have similarities, there are some striking differences, such as the subject sections.

What do the ACT and SAT focus on?

You spend less time answering questions in the ACT than the SAT. Moreover, in the ACT, you need to analyze data and experiment in the science part. In the SAT, you need to answer precise vocabulary questions. The test you want to take depends on your goal and choice. Therefore, you could scan practice tests to determine your needs and skills.

Do I need to aim for a high score in the ACT?

Universities and colleges use the scores as part of the criteria in granting scholarships and admitting students. Although there are many other factors to consider, the ACT score plays a significant role in deciding whether a student cuts.

Am I too late to study if my ACT is in 2 weeks?

No, you’re not. The preparation time may be shorter, but it’s better to study than not do any preparation. Publishers of ACT prep books recommend allocating 2 to 3 months of studying to get a good score.

How do I prepare for the ACT?

You can use prep books, take online review classes, or hire a personal tutor, among many others, to study for the exam. Understanding the test, learning test-taking skills, and techniques, and applying these are the keys to prepare well.

Can I skip attending in-person prep classes and just study using an ACT prep book?

There’s no definite answer to this since this depends on what kind of student you are. If you’re the type who could study independently well, this could work. If not, it would be best for you to enroll in a prep class to focus. Then, you can use your prep books to reinforce what you learned in class.
