About this app

A passage with numbered underlined portions, four choices and NO CHANGE: that is how ACT English is set, and how this app sets it. Mathematics problems come with worked explanations, Reading shows the passage with every question, and Science asks you to read tables, figures and experiments; together you can practise with over 500 ACT questions across 11 categories, from Production of Writing to Interpretation of Data.

Five ways to practise:
- Question Bank: sets of up to 10 in each of those categories, graded Easy, Medium or Hard.
- Sprint: timed rounds at ACT pace for one section or all four, with a pace clock on every question.
- Full-length tests: English, Mathematics, Reading and optional Science, each section on its own clock and one way only, like test day.
- Mistakes: every wrong answer kept with its explanation, ready to review.
- History: every finished set, run and test, with your answers.

While you work, mark a question for review, cross out choices, highlight a sentence or report a problem. Check your answer to see why the key is right.

Ask Tutor is an AI tutor for hints before you check and a walk-through after. It asks for your consent before the first message, and nothing you type is sent to the AI model until you agree.

A finished full-length test shows an estimated 1-36 score per section, a Composite from English, Mathematics and Reading, and a STEM score from Mathematics and Science. Analytics tracks questions attempted, accuracy by section and category, weekly activity and your study streak. Today's plan on Home picks what to practise next, and optional reminders count down to your test date.

You sign in with e-mail or Google. Without a subscription you get a daily allowance of questions, Set 1 of each category at every level it offers, and every explanation. Premium is an auto-renewing subscription, monthly or yearly, that lifts the daily cap, opens Sets 2 and up, and adds Ask Tutor. The charge goes to your Google Play account when you confirm the purchase. The subscription renews automatically until you cancel it. Manage or cancel it in the Google Play Store under Payments & subscriptions > Subscriptions, and use Restore Purchases in Profile on a new device. Delete account in Profile removes your account and its practice data. Terms of Use: https://prepclass.io/terms
