Free, full-length ACT practice tests.

Each test below mirrors the real ACT format — 215 multiple-choice questions across English, Math, Reading, and Science — and is broken into timed sections you can take individually or back-to-back as a full mock. All questions are original, written in the style and difficulty range of the actual exam.

How to take a full-length test

Find a quiet two-and-a-half-hour block. Use a stopwatch (your phone is fine, but airplane-mode it). Go through the sections in order: English (45 minutes), Math (60 minutes), Reading (35 minutes), Science (35 minutes). Do not pause the timer. If you don't finish a section, mark where you ran out — that's data, not failure.

After the test, score it section by section using the score calculator. Then go back through every question you missed and write down — in your own words — the rule you violated. This is the single highest-leverage thing you can do in test prep.

How these tests differ from the real ACT

The real ACT is copyrighted by ACT, Inc., so we cannot reproduce its questions. Every question on ACT Vault is original. We've matched the format (passages with line numbers in Reading; data-table research summaries in Science; integrated grammar and rhetoric in English; the 60-question pre-algebra-through-trig spread in Math) and we've calibrated difficulty against publicly released score-conversion charts.

Use these as realistic, unlimited-quantity practice — and once you've worked through several, supplement with the official ACT-published red book for a final sanity check.
