Less guessing. More points.

Most students lose time deciding what to study. ScoreOS makes that call for you every day, based on your test date, your schedule and the questions you actually miss.

1Every day

Open the app, see one clear next step.

Today shows your streak, the days left until your test and a single “Up next” task picked from your plan and your recent misses.

  • Tick off today’s tasks as you go
  • A Question of the Day that takes under a minute
  • Your week at a glance: questions, accuracy, active days
2When you get one wrong

Every miss explained, then tracked until you fix it.

Wrong answers show why your choice doesn’t work and why the right one does. Each miss lands in your mistake history, tagged by cause, and comes back for a retest a few days later.

  • Practice adapts to your weakest skills
  • Every set tells you why each question was picked
  • Spaced review so fixes actually stick
3Around a busy week

A plan that fits around practice, games and homework.

Tell ScoreOS which days you can study and for how long. It schedules lessons, practice and the free official Bluebook tests up to your test date, and moves whatever you miss.

  • Day, week and month views
  • Missed a day? Tasks reschedule within your free time
  • Log study you did outside the app
4Five minutes a day

Make it a habit, with friends.

A daily brain challenge, speed sprints and a weekly tournament. Accuracy beats speed, every game ends with explanations, and you choose who sees you on leaderboards.

  • Seven games, two to twelve minutes each
  • Challenge a friend to the same questions
  • Streaks, levels and streak freezes
5Choosing where to apply

See how your score compares, without the guesswork.

Save colleges to track deadlines and application checklists. Score comparisons separate published minimums from reported ranges, link to their sources and never promise admission.

  • Deadline countdowns and reminders
  • Outdated data is flagged, not hidden
  • An application checklist for every school

Questions, answered.

Do I need an account?

No. Start as a guest and your progress is saved to a private guest account. Add an email whenever you like to keep it and continue on another device.

Are these real SAT questions?

They’re original questions written to the official Digital SAT domains and skills, not College Board questions. For full-length adaptive tests, ScoreOS schedules the free official Bluebook tests and lets you log your scores.

What does Plus add?

Unlimited adaptive practice (Free includes 30 questions a day), timed exam-like sets, a custom set builder, advanced analytics, more library storage and 200 Coach credits each paid month.

Can I try it before setting anything up?

Yes. Choose “Try the demo” on the welcome screen to explore a fully set-up account first.

Does it work on my phone?

Yes. ScoreOS runs in your phone’s browser with a bottom tab bar for Today, Practice, Plan and Games. There’s nothing to install.

Can my friends see my scores?

Only what you choose. Leaderboards show display names, and you can limit who sees you to friends or opt out entirely.

Walk in on test day knowing you did the work.
