What is the Best ACT Prep Book?
Let’s review the features of the top six ACT test prep books on the market, compare them to each other, and rank each of them overall.
What Should I Look for in an ACT Prep Book?
Full-Length Practice Tests
When it comes to acing the ACT, there is one proven strategy to crush it—practice! Taking as many practice tests as you can is the number-one way to be totally prepared come test day. The best books offer at least three complete practice tests, with answers that are detailed and easy to understand. The more tests that come with your book, the better, but online tests are great as well because they get you used to the computer adaptive tests that you’ll see when you sit for the ACT.
There were three prep books that had the most tests. The Official ACT® Prep Pack has seven, and The Princeton Review and Barron’s both offered six full-length tests. Kaplan came in a close second with five. The Official ACT Pack 2020 was the winner because their tests are closest to the actual test since they basically work with the test makers.
Top Pick: Official ACT® Prep Pack 2020
The number and quality of questions have a big impact on how well you are prepared for the ACT—the more questions, the better! The questions also need to mirror the style and difficulty of the real ACT. Questions that are too hard or too easy are really not helpful. The Official ACT® Prep Pack 2020 and Manhattan Prep’s 5lb. Book of ACT Practice Problems offered the most practice of all the prep books—by a mile! You can practice using these study guides and probably not get through them all. But we give the nod to the Official ACT® Prep Pack 2020. They offered the most realistic practice questions because they work directly with the makers of the ACT.
Top Pick: Official ACT® Prep Pack 2020
Comprehensive Answer Explanations
For the best test preparation, you also need detailed explanations as to why the correct answer is right, so you can understand the concepts behind the questions. It’s not enough to complete problems and see the correct answers. The book is worthless if it doesn’t explain the answer in terms that you understand. The best ACT study guides will have detailed, easy to understand answer explanations to each question. That way, you’ll be able to answer comparable questions if they turn up on test day.
Manhattan Prep’s 5lb. Book of ACT Practice Problems is great for those who want systematic, easy-to-follow walkthroughs. They provide comprehensive and answers all 1,800 questions.
