Common Questions
Everything students ask before signing up
Why does MentisPrep have a free SAT prep?
Because we believe test prep shouldn't be a privilege. Our test prep platform includes unlimited mock tests, AI analytics, and a personalised study plan — more than most paid platforms offer. We want every student to be able to access great prep, regardless of budget.
How is this different from Khan Academy's SAT prep?
Khan Academy is great for concept videos. MentisPrep is a full practice platform — unlimited full-length mock tests in the real Bluebook interface, AI that tracks 200+ skill markers, and a personalised study plan that rebuilds after every session.
How many mock tests should I take?
Most students who see significant score movement take at least one full mock every 2 weeks, plus targeted skill drills between tests. Your study plan will recommend the right cadence based on your exam date and starting score.
Who should use MentisPrep?
Any student preparing for the Digital SAT — whether you're starting 6 months out or 2 weeks before the test. It works especially well for self-motivated students who want data-driven feedback instead of just watching videos.
Is this really identical to the actual Digital SAT?
Yes. Our test environment replicates the official College Board Bluebook interface — same layout, same Desmos calculator, same timing modules, same adaptive difficulty engine. Students who practice here report zero interface surprises on test day.
Can I pause a mock test and finish it later?
Yes — your progress saves automatically. Pick up exactly where you left off, whether that's an hour later or the next day.
Is my data private and safe?
Yes. We don't sell your data, share it with advertisers, or use it for anything other than personalising your study experience. You can delete your account and all associated data at any time.
I just started SAT prep. Where do I begin?
Take a diagnostic mock test first — it takes about 2.5 hours and gives our AI a baseline to build your personalised study plan from. From there, your daily plan tells you exactly what to do each day.
