Questions

Can I use it for free?+

Yes. 5 questions a day forever, plus the diagnostic and a full length adaptive test, no credit card needed. Unlimited practice, the AI tutor and the missed-question review are Pro.

Are the questions real CollegeBoard questions?+

No. Every question is original, written to the College Board skill codes and matched to the format, style and difficulty of the real digital SAT.

How does it know what I'm bad at?+

Every answer moves a rating for that one skill, so it is measuring you skill by skill rather than giving you one score. After a handful of questions it can tell you which specific things are costing you points, and it keeps aiming at those.

What happens to questions I get wrong?+

They go into your mistake bank and come back on a schedule: two days later, then a week, then three weeks, then two months. Getting one right pushes it further out, getting it wrong again resets it. That spacing is what makes it stick instead of you re-reading the explanation and forgetting by Friday.

I already took a practice test somewhere else. Can I use it?+

Yes. Upload a screenshot of your Bluebook review screen or score report and it will work out which skills you missed, then weight your practice toward those. You do not have to re-answer everything here first.

What is covered?+

Both digital SAT sections, Reading and Writing and Math, down to the individual skill, plus full length adaptive practice tests.

Can I cancel anytime?+

Yes. Cancel in one click from your profile, no fees. Your progress is always saved.

Does it work on my phone?+

Yes. Any browser, any device, no app needed.
