The ACT is one of the two main admissions tests for undergraduate degrees in the USA, and it’s also accepted by universities in other countries. It changed in 2025, so it’s important to practise with up-to-date material. The good news is that you can prepare well without paying for practice tests: ACT itself, test-prep companies and public libraries all offer free ones.
We’ve collected 50 of them in one place, with a link to each: official ACT practice tests, free full-length mocks, section tests for English, Math, Reading and Science, and free question banks. Some entries are a set of several tests, so in total you’ll find around 100 free practice tests and question sets here. Every link was checked in October 2026.
First, a quick reminder of the current ACT format
Since 2025, the ACT has been shorter, and the Science section is optional. The current (sometimes called “enhanced”) ACT has:
- English: 50 questions in 35 minutes.
- Math: 45 questions in 50 minutes.
- Reading: 36 questions in 40 minutes.
- Science (optional): 40 questions in 40 minutes.
- Writing (optional): one essay in 40 minutes.
- Your Composite score (1 to 36) is the average of English, Math and Reading only. Science gets its own score if you take it.
Older ACT practice tests have 215 questions (75 English, 60 Math, 40 Reading and 40 Science). The question types are very similar, so older tests are still useful practice, but use the current format for your timed, full-length rehearsals. We’ve marked the older-format tests clearly below.

How to get the most from free ACT practice tests
- Start with a diagnostic: take one official test, or a short diagnostic, to find your starting score and weakest section.
- Use official tests for full rehearsals: ACT’s four free practice tests are the most accurate. Spread them out across your preparation and keep one for the last week.
- Practise the current timing: the ACT is fast. Practise finishing each section in time, especially English (35 minutes for 50 questions).
- Decide early about Science and Writing: check whether the universities on your list want them, and only practise the optional sections if you’ll take them.
- Review every mistake: keep an error log and look for patterns. It’s worth more than taking test after test.
- Look out for free proctored tests: libraries, schools and tutoring centres often run free practice ACTs with a live proctor. They’re great preparation for test-day pressure.
Studying in the USA?
Many US universities are test-optional, but a strong ACT score can still help your application and scholarship chances, and some universities require one. Check each university’s admissions page. For help choosing where to apply, see our Study in the United States guide, take our free study abroad assessment, or browse universities on our Universities page. Applying to business school later?
