- Free
- Works offline
Adaptive ACT prep — English, math, reading, and science tuned to your level, in 5-minute bursts or longer sessions.
Free, works offline, no ads.
How it works
- Free to use, with no ads and nothing to buy.
- Works offline once it has loaded, on a phone or at a desktop.
- Signing in is optional. Without an account everything stays on your own device; an account only backs your progress up so it follows you to another one.
What the app does
- Start with a diagnostic: a short adaptive test that places you on every section.
- Practice that adapts: each question is picked for your level, and the ones you miss come back the next day.
- A short lesson for every skill: the rule, worked examples and five quick drills.
- Full-length practice tests, timed like the real exam and scored on its own scale.
- Set a target score and your exam date (a retake date too); the app counts down and shows the gap.
- Print a worksheet, work it on paper, then enter your answers to score it.
The exams it covers
- ACTACT — college admissions exam (English, Math, Reading, Science)
