NewThree full-length adaptive mocks are live

Know your score. Then follow the plan that raises it.

Adaptive full-length mocks, interactive simulations, and a daily plan that tells you exactly what to study next.

Free during the betaNo card required

Bluebook administers a test. Khan Academy teaches a course. Neither one tells you what to do tomorrow morning.

Mock examsAvailable now

The real thing, on a real clock.

Two modules per section, and the second one changes based on how you did on the first — the same adaptive structure as the Digital SAT.

  • Server-held timer
  • Module-locked
  • Real 10-minute break

A Reading and Writing question in the exam runner: the passage on the left and the question with four answer choices on the right, the module name and the countdown at the top, Mark for Review above the question, and the question menu, Back and Next along the bottom.
Score analysisAvailable now

A score you can actually trust.

A range with its confidence stated, plus exactly which of the 30 SAT skills cost you the points.

  • Score band, not a guess
  • Per-skill loss
  • Pacing breakdown

The report card chapter “What do I know?”: each content domain of Reading and Writing and of Math drawn as a row of squares, one per question, filled when the answer was right, with the skills that cost questions listed underneath.
A sample account, not a real student's results.
Interactive drillsAvailable now

Drag it. Don't just read it.

Eight draggable simulations turn the abstract parts of SAT Math into something you can move and see. This one is live — try it.

  • 8 simulations
  • Answer to unlock
  • Weakness-ordered drills

Slope is a rate

Graph of y = 1.5x + 2. A right triangle on the line has a run of 1 and a rise of 1.5 — that rise IS the slope. The line crosses the y-axis at 2; its x-intercept is -4/3.

The triangle is always one step wide, so its height is exactly m — that is what the slope measures: how far y moves for one step of x. Drag b and watch the line slide without ever getting steeper.

The progress panel on the dashboard: level 14 with the points needed for the next level, a 14-day streak, the rest days that cover a missed day, and total XP, above a grid of the last 26 weeks of study activity.

Three steps, then repeat.

1

Sit a baseline mock

One full-length adaptive exam, properly timed, so your starting number is real.

2

Get a plan built from it

Every mistake is scored by skill and by time, then turned into a daily plan sized to the hours you actually have.

3

Drill the weak spots

Short lessons and simulations on exactly the skills costing you points — reordered every time you sit another mock.

Why you can trust what you see

Questions written by AI, checked automatically and reviewed by people, every calculation explained, and every company that handles your data named. We would rather show you exactly how than have you wonder.

We tell you how confident we are in your score

A practice score is an estimate, and anyone who reports it to the nearest point is guessing. We give you a range and the confidence behind it, and it narrows as you sit more mocks. The method is written down and public.

Checked by machines, then reviewed by people

Questions are solved blind by three AI models that never see the answer key, and their arithmetic is run as code rather than trusted. Then a person — the founder or an SAT tutor — reviews the question and its key. During the beta those reviews are still under way, so every question has a report button.

Original questions and original passages

Every question here is written for Preptics. We do not reproduce real SAT questions or passages — they are the College Board's copyrighted work, and a practice test built from them teaches you the wrong thing anyway. Our reading passages are built from public-domain and openly licensed sources, and we record where each one came from.

Found a bad question? It comes down in minutes

Every question has a report button. Once a question crosses a report threshold it is pulled from circulation automatically, and affected scores are recalculated so no one is penalised.

Our software does the maths. AI only writes.

Scores, skill estimates, review timing and your plan are calculated by code — and every calculation is written down, with its thresholds. AI drafts wording from numbers we already worked out, never inside a timed test, and only through providers that keep nothing.

Every company that touches your data, named

Not "trusted partners": each service, what it receives, and a link to its own policy. No ad networks, no tracking pixels, no analytics cookies.

What people say

Where a score is shown it comes from an exam actually sat here. We cannot type it in on anyone’s behalf.

No reviews to show yet.

We are new, and we would rather show you nothing than show you something we wrote ourselves. Sit a free mock, and if it helps, tell people — your score is attached automatically from the exam you actually sat.
