The best free ACT prep resources in 2026

Official ACT prep through released practice tests from ACT.org stands out as a cornerstone resource. These materials reflect the test's actual structure, making them invaluable for effective practice.

Why this matters

When preparing for the ACT, high school students are aiming to achieve the scores needed for college admissions and scholarships. Often, budgets for test preparation are tight, making free resources critical in providing equitable access to academic success. Understanding which free resources genuinely aid preparation versus those that serve as lead magnets or teasers guides students in making informed study decisions.

When to upgrade to paid prep courses

While free resources are helpful, there may be scenarios where a structured course becomes necessary.

They offer structured pathways and sometimes score guarantees.

How to choose the right ACT prep resources

When selecting ACT prep resources, consider the gaps in your current knowledge. Start with free resources like official practice tests and educational videos to identify these areas. If progress stalls, look into paid options for more intensive preparation. Match the format (e.g., videos, live classes) to your learning style. If a score guarantee is critical to you, explore courses like the ACT 31+ Course by The Princeton Review.

• Begin with free tests to identify strengths and weaknesses
• Upgrade if needing structured study or score improvement
• Consider learning style (video, live class) when choosing courses
• Use score guarantees as a tie-breaker in deciding between paid courses
