The short answer
Start with official ACT practice. Timed sections help you learn its pace. Add a question bank for volume, a course for structure, or an AI tutor for explanations, chosen after a timed official practice test, not before.
Key facts
- ACT.org publishes free official practice material, including full-length tests.
- ACT prep needs its own pacing work; SAT timing habits do not transfer cleanly.
- The Science section rewards data-reading speed over science recall.
- Fewer high-quality ACT tools exist than SAT tools, so official material matters more.
The options, by job
Provider details were checked against public pages on October 2, 2026. Prices, question counts and included features change often, so confirm anything decision-critical before paying.

| ACT Online Prep (ACT) | Official-aligned practice program | Paid; see ACT's site | Self-directed |
| Paid question banks | Volume and explanations | Subscription; varies | Not all mirror ACT pacing |
| Princeton Review SAT & ACT Self-Paced | Both tests in one program | $499 (checked Oct 2, 2026) | Only sensible if you are genuinely undecided |
| AI tutor | Instant error analysis at scale | Varies; ExamScore is $199 one time | ACT practice on ExamScore is in build |
Pace is the skill the ACT tests hardest
The ACT is linear and moves quickly from question to question. Many students who know the content still lose points to speed, especially in Reading. An app that only teaches content will not fix that.
Judge any ACT tool by whether it makes you practice whole timed sections, shows where the minutes went, and helps you decide what to skip.
- Practice full timed sections, not just untimed question sets.
- Record the question number where you first fell behind.
- Decide skip rules in advance and rehearse them.
An honest note about ExamScore and the ACT
ExamScore's ACT practice is in build; Digital SAT practice is the product that is live today. If you are preparing for the ACT right now, use official ACT materials as your core and treat our ACT guides as planning support.
We would rather say that plainly than sell you something that is not ready.
“For the ACT, buy realistic timed practice first. Everything else is secondary.”
Run an ACT-specific trial
Begin with current official ACT practice and identify whether English, Math or Reading is losing you the most time. Test an app with a timed set in that section. Does it reflect enhanced ACT question counts and pacing, and can you see exactly where the minutes went? A SAT-style practice bank with an ACT label is not enough.
If you plan to take optional Science, check that it offers data-reading practice without implying Science contributes to the enhanced core composite. Use the official test maker's current instructions as your reference and compare paid options only after you can describe the gap.
- Verify the enhanced format and timing.
- Compare explanations for a missed question.
- Keep optional Science separate from core composite planning.
Questions people ask
- What is the best ACT prep resource?
- Start with the official free practice from the test maker, because the pacing and question style are the whole challenge. Add a paid tool only when you need more volume on the section costing you the most composite points.
- Where do I find free official ACT practice?
- On the ACT's own website, which publishes practice questions and full-length practice tests at no cost. That is the reference point any other resource should be judged against.
- Do SAT apps work for the ACT?
- Partially for content, poorly for pacing, and not at all for Science. Because time pressure is the defining ACT difficulty, practicing at SAT timings can leave you underprepared for the real thing.
