Frequently asked questions

Yes — the mock structure matches how the College Board actually runs the test today: two 32-minute Reading and Writing modules and two 35-minute Math modules, with the second module in each section routed by how you did on the first. If the College Board changes the format, we update the engine rather than leave you practising against a test that no longer exists.

Every mock is scored against your actual answers, correctness and time spent, rolled up by SAT skill rather than just by section. You get a skill-by-skill breakdown of exactly where points are being lost, a score band with a stated confidence instead of a fake-precise number, and an estimate of how well you know each skill, shown as a range. Your study plan rearranges itself from those estimates after every set of drills, lesson and mock. Every calculation is explained, with its thresholds, on the How Preptics works page.

In two places, both written words rather than numbers. After you submit a mock, an AI model drafts the wording of your debrief from a summary our software has already calculated — score ranges, skills, pacing — which carries no name, email or account. And you can ask for a one-sentence explanation of a phrase in lessons, drills and review; that phrase is sent and nothing is kept. Neither is available in a timed test, and requests go only to providers that have committed to keep nothing, never to DeepSeek's own service. Your scores, skill estimates and plan are calculated by our own software. The How we use AI page lists everything, including limits.

From your skill estimates, which change as you answer. Lessons go where your estimated mastery is lowest; drills put questions due for review first, then the skills where your recent results are moving — where practice is paying off or something is slipping — with a nudge towards skills you have barely tried. After a set of drills, a lesson or a mock, the plan checks whether anything changed and rearranges itself if it did, without undoing work you have finished, and your daily mission tells you what moved.

You should use both — they are good, and Bluebook is the real thing. What they do not do is tell you what to study today, track your proficiency skill by skill, or show you how you rank against everyone else preparing. Bluebook administers a test; Khan Academy teaches a course. Preptics is the daily routine between them. During the beta all of it is free. After launch two mocks stay free, and if the rest is not worth $9.99 to you, we would rather you used those than felt misled.

Yes. Reading and Writing is two 32-minute modules and Math is two 35-minute modules, and in each section the second module is selected by how you did in the first — the same multistage structure as the real test. Each module has its own clock held on our server, and once a module closes you cannot go back to it.

Because a range is the honest answer. Turning a raw count into a 400–1600 score requires equating against a reference population, and any new platform reporting you a precise number is guessing at a precision it does not have. We show a band and how confident we are, and the band narrows as you sit more mocks. You can read exactly how it is calculated.

A projected Reading and Writing score, a projected Math score and a total — each as a band with a confidence level. Then a skill-by-skill breakdown of where the points went, your pacing against the real module limits, and your rank this season. Then you can review every question with an explanation for each answer choice.

Today, yes. Preptics is a platform for standardised test preparation, and the Digital SAT is its first track: we are building it properly before starting another. PSAT/NMSQT and then the ACT are planned as the next tracks, and phone and tablet apps are planned after the web app. None of them has a date. If you need a different exam, ask for it on the feedback page, because requests change the order.

Yes, and we would rather tell you than have you guess. Questions are written with Anthropic's Claude models and then put through seven checks before publication — including being solved blind by three models that never see the answer key, and Math verified by executing the arithmetic rather than trusting it. Anything ambiguous, mis-keyed, duplicated or off-specification is discarded. Then a person reviews each question and its answer key: our content auditor, an admission-test instructor who prepares students for the SAT and other standardised tests, has reviewed every question in the published practice tests. If one still looks wrong, report it — three reports take a question out of circulation automatically. One honest limit: the three blind solvers are all Claude models today, so they can share a blind spot, which is why a person checks too.

No, and deliberately not. Real SAT questions and passages are the College Board's copyrighted work. Every question and every reading passage here is original: passages are written from public-domain and openly licensed source material, with the provenance recorded.

Report it. Every question has a report button, and once a question crosses a report threshold it is automatically pulled from circulation while we re-verify it. If we remove a question, affected scores are recalculated so removing it can never lower your score.

Yes. While Preptics is in beta every account gets every mock, lesson and drill, with no card and no trial clock. Nothing is on sale except the Founder's Pass, which is optional and unlocks nothing extra. When the beta ends the passes go on sale at the launch prices on the pricing page; we will email you before that happens, and your scores, plan and history stay yours either way.

No. There is no time-boxed trial that needs a card to unlock. During the beta everything is free; after it, two full adaptive mocks with every explanation stay free for good. You only reach for a card if you decide to buy a pass after launch.

A voluntary way to back Preptics while it is free. You pay what you want — from $1, with $5 suggested — and receive a numbered Early Supporter Certificate. It does not unlock anything, because during the beta everything already is, and not buying it changes nothing. It is a single payment that never renews, and we refund it in full within 14 days if you ask.

No. The passes are not on sale during the beta; when they are, both the 3-month and the 12-month pass will be single payments, and neither will charge you again. If your test date moves you can add 30 days for $4.99, and that time is added to what you already have rather than replacing it. We are aware that most of the industry does the opposite. You sit the SAT once or twice and then you are done with us — billing you out of inertia after that would be taking money for nothing.

During the beta there is nothing to buy. Once passes go on sale, whoever pays can enter your email address at checkout and the access lands on your account, with the receipt going to the person who paid.

Yes. The Founder's Pass is refunded in full within 14 days of paying — just ask. Once passes are on sale, a pass is refunded in full within 14 days if you have used less than 20% of the material; because questions are delivered one at a time and recorded, we can measure that exactly. Beyond that, ask us — we read every request.

Not yet, and we are aware these prices do not mean the same thing everywhere. A large share of SAT candidates sit it outside the US, and regional pricing is on the roadmap. If cost is the blocker for you, tell us — that feedback is what moves it up the list.

13 or older to create your own account. If you are under 18, your account is not on the public leaderboard unless you turn that on — the opposite of the default for adults.

No. Ranking is off by default if you are under 18 and opt-out at any time for everyone, and you keep every other feature including your own percentile. You are pseudonymous by default — we never ask for your real name.

Yes, in settings, with no paperwork — but to be clear, that only affects practice here. Extra time on the real SAT has to be approved by the College Board's Services for Students with Disabilities well before your test date; setting it here does not apply for it. Extended-time attempts are ranked in a separate pool so it is never an advantage or a disadvantage.

The ones needed to run the service, each named on our Third-party services page with exactly what it receives: Supabase stores your account and study records, Vercel hosts the site, Cloudflare runs our DNS and the sign-up bot check, Lemon Squeezy takes payment as merchant of record, Zoho sends email, OpenRouter routes AI requests to providers that keep nothing, GitHub runs the weekly job that recalibrates question statistics from answers without names attached, and Umami counts visits, and a short list of actions such as which sign-up button was pressed, on our public pages without cookies — with a switch to turn it off. No advertising networks, no tracking pixels, and we do not sell data.

Yes, from settings, and it is immediate. You can also export everything we hold about you as a JSON file first. Records of purchases are kept for accounting but are no longer linked to you.
