Digital SAT practice tests

Full-length adaptive mocks that behave like the real thing: two sections, two modules each, the second module routed by how you did on the first, and the same clock. You get a score range rather than a single number, a breakdown of which skills cost you points, and every explanation for every answer choice — including the ones you got right.

What a full-length adaptive mock actually is

The Digital SAT is not a fixed test that everyone sits identically. It is a two-stage adaptive test, and the adaptation is the part most practice material gets wrong. You sit four modules in one sitting — two for Reading and Writing, two for Math — and the second module in each section is chosen by how you performed on the first.

  1. Reading and Writing, module 1

    27 questions, 32 minutes. Everyone gets the same difficulty mix.

  2. Reading and Writing, module 2

    27 questions, 32 minutes. Easier or harder, decided by how you did on module 1. This is the routing step.

  3. Math, module 1

    22 questions, 35 minutes. Built-in calculator throughout, as on the real test.

  4. Math, module 2

    22 questions, 35 minutes. Routed the same way, independently of Reading and Writing.

Reading and Writing module routingEveryone sits the same first module of 27 questions in 32 minutes. The test then routes to one of two second modules: a harder one with a ceiling of 800, or an easier one whose ceiling is below 800. Both second modules have the same question count and time limit as the first.Module 127 questions · 32 minSame for everyoneroutedonceModule 2 — harder path27 questions · 32 minCeiling: 800Module 2 — easier path27 questions · 32 minCeiling: below 800Separate conversion tables — the sameraw count scores differently
One routing decision per section, taken at the module boundary. Nothing you do inside a module changes which module you are in.

Between the two Reading and Writing modules and the two Math modules there is a ten-minute break, and the whole sitting runs about two hours and fourteen minutes. Our mocks run the same clock, the same module boundaries and the same routing rule. A practice test that is not adaptive is not measuring the same thing as the test you are going to sit — it can tell you whether you know the content, but it cannot tell you what you would score.

Why you get a range instead of a number

Every practice platform reports a score. Almost all of them report a single number, and almost all of those numbers are more confident than the evidence behind them supports. Converting raw correct answers into a 400–1600 scaled score requires the College Board's equating data. That data is not public. Nobody outside the College Board has it, including us.

So we calibrate our own conversion tables, one per second module, and then we widen the result on purpose. After one mock you get a band about 60 points wide either side of the estimate. After two it narrows to ±45, and after three or more to ±40. The band tightening is not cosmetic — it is what more evidence actually buys you.

A number like “1310” from a practice test is a guess wearing a lab coat. “1270–1350, moderate confidence” is the same guess told honestly, and it is more useful: it tells you whether the school you are aiming at is inside your range or outside it, which a false point estimate cannot.

How a projected score band narrows with more mocksA horizontal score axis from 1100 to 1500. After one mock the reported range is 1230 to 1350, described as low confidence. After two it is 1245 to 1335, moderate confidence. After three or more it is 1250 to 1330, good confidence. The centre of every range is 1290.11001200130014001500estimate 1290After 1 mock±60low confidenceAfter 2 mocks±45moderateAfter 3 or more±40good
The band stops narrowing at ±40. What remains at that point is calibration error, and watching you sit a fourth mock does not reduce it.

What is free, and where it stops

Two complete adaptive mocks are free, with no card and no trial clock. Free does not mean crippled: you get the full score band, both section scores, the skill-by-skill breakdown, and every explanation for every answer choice — not just the correct one. You also get the study planner and a place on the global leaderboard.

That is how it will work at launch. Right now there is no line at all: Preptics is in beta, and every mock, lesson and drill is free for every account. At launch the pass will add volume and depth — every mock as it is released, all lessons and unlimited skill drills, and analytics across every mock — for $9.99 for three months or $24.99 for twelve. Neither will auto-renew.

When this is the wrong tool

Three cases where you should use something else, said plainly rather than buried:

  • You want the real, leaked question bank. Those are the College Board's copyrighted work, we do not have them, and memorised banks stop working the moment the test rotates.
  • You want a single confident number after one attempt. We will give you a range, and after one mock that range is ±60 points wide.
  • You have not booked a test date and do not intend to. The planner works backwards from a date; without one it has nothing to plan against.

If you want free foundational instruction rather than measurement, Khan Academy's official course is genuinely good and costs nothing. We are for the part after that: finding out where you actually stand, and what to do about it in the weeks you have left.
