10 Best ACT Prep Books 2025 in the United States

The Official ACT Prep Guide 2024-2025 is a comprehensive resource designed for students in grades 10 to 12 preparing for the ACT exam. One of its major strengths is the extensive content coverage, which includes 9 full-length practice tests that mimic the actual exam format, helping students get accustomed to the test's structure and timing. Additionally, the book features 400 digital flashcards and an online course, which can be very beneficial for interactive learning and reinforcing key concepts. The detailed answer explanations for each practice test question are another positive aspect, aiding in understanding mistakes and improving performance.

The test-taking strategies included in the guide can help students develop effective approaches to tackle different sections of the ACT, which can be particularly useful for first-time test-takers. However, the extensive nature of the book, with 1120 pages, might feel overwhelming for some students. The book's physical weight of 4 pounds and its large dimensions (8.5 x 2.8 x 10.8 inches) might make it less portable and convenient for on-the-go study sessions. Some users may also find the difficulty level of the practice tests challenging, which could be discouraging rather than helpful.

Despite these drawbacks, the supplemental resources like the online course provide added value, making it a robust tool for thorough ACT preparation. Those who prefer a structured, comprehensive approach to studying will likely benefit the most from this guide.

With 364 cards included, there's a substantial amount of material to work through, which is ideal for thorough preparation. The cards include answer explanations and are published in English by Mometrix Media LLC, with difficulty levels appropriate for high school students (16 years and up).

These study cards could be particularly beneficial for students who prefer active recall and quick, repeated review sessions over more extended study periods. They might need to be complemented with other study materials for those who need more in-depth practice tests and a wider range of supplemental resources.
