What is the Digital SAT?

Everything about the current format: how the two sections are built, what module-level adaptivity actually changes, what Bluebook gives you on screen, and how the score is produced.

The Digital SAT is the current form of the SAT, taken on a computer in College Board's Bluebook application. It has two sections — Reading and Writing, then Math — and each is split into two separately timed modules. There are 98 questions and 2 hours 14 minutes of testing time, with a 10-minute break between the sections. The total score runs 400 to 1600, built from two section scores of 200 to 800.

The digital exam replaced the paper SAT internationally in March 2023 and in the United States in March 2024. It is a different test, not a reformatted one: the passages are shorter, the section is adaptive, a calculator is allowed throughout Math, and the essay and subject tests are gone. A large amount of SAT advice still online describes the old exam.

Structure

The two sections, module by module

Each module has its own clock. Time left over in module 1 does not roll into module 2, and no time moves between sections.

Adaptivity

What module-level adaptive actually means

The Digital SAT is multistage adaptive at module level, not question by question. Each section has two modules. Module 1 is the routing module: it carries half the section's questions in a broad mix of easy, medium and hard. Your performance on it decides whether module 2 is the higher- or lower-difficulty form. The section score is then built from your work across both modules, and it accounts for how hard the questions you actually saw were, so it is not a raw count of correct answers. The two sections adapt independently of each other.

This is worth stating plainly because the opposite claim is common online. The test does not get harder or easier after each individual answer.

Routing is not a published ceiling either. College Board says a score reflects the difficulty of the questions a student saw as well as how many they answered correctly, but it has never released a maximum score for the lower-difficulty second module, and nobody outside College Board can derive one. Any specific cap quoted online is invented.

Two things follow. Module 1 accuracy matters more than its question count suggests, because it is scored like any other module and it also decides which second module you see. And because adaptivity happens between modules rather than within one, you can still move freely inside a module: skip, flag, and come back until that module's timer ends.

How one section plays out

  1. MODULE 1

    Half the section's questions, spanning easy, medium and hard. This is the routing module: it is measuring you, not just scoring you.

  2. ROUTING

    Bluebook selects the second module — on average harder or easier than the first — from your performance so far.

  3. MODULE 2

    The remaining questions at that targeted difficulty. Both modules count towards the section score, and how hard the questions were is part of that calculation.

The two sections route independently. A strong Math routing module does nothing for the Reading and Writing section.

How module-adaptive scoring worksSAT strategies

On the day

What Bluebook gives you on screen

Bluebook is College Board's own digital testing application. The exam runs in it, and the official full-length practice tests are taken in it too, so practice conditions match test day exactly.

Calculator, all the way through

A calculator is permitted on the entire Math section — there is no no-calculator module. Bluebook has Desmos built in with both a graphing and a scientific mode, and you can bring your own approved non-CAS calculator as well.

Reference sheet

A reference sheet of common formulas is on screen throughout the Math section, so memorising them is not what the section rewards.

Test-taking tools

Bluebook also provides annotation, a line reader, an answer eliminator, a flag-for-review tool, and a countdown clock for each module.

Because the same app runs both the exam and the official practice tests, there is no reason to first meet these tools on test day. Download Bluebook from College Board and take a full-length practice test in it before you sit the real one.

College Board publishes test dates and registration deadlines for the whole year at once, but score-release dates a term at a time. Rows marked projected are this site’s estimate from the pattern every administration has followed — release on the second Friday after the test — and are replaced with the published date as soon as College Board lists it. Test dates and registration deadlines in this table are not projections.

Digital SAT FAQ

The digital SAT replaced the paper test internationally in March 2023 and in the United States in March 2024. Any description of the SAT as a three-hour, 154-question paper exam with a no-calculator maths section describes a test that no longer exists.

It is shorter and the passages are much shorter, but it is not easier. The time per question is more generous than on the paper test while the reasoning demand per question is higher, and the adaptive structure means a strong first module routes you into a genuinely harder second one.

Within a module, yes. You can move freely, flag questions for review and change answers until that module's timer expires. Once a module is submitted you cannot return to it, and time does not carry over into the next one.

You test on a device running Bluebook — your own laptop or tablet, or a school-managed device. Some test centres lend devices, but that has to be requested well before test day, so register early if you need one.

No. Neither is part of the SAT any more. The total score is made up of the two section scores only.

Each section is scored from 200 to 800 and the two are added for a total of 400 to 1600. Scoring accounts for how hard the questions you saw were as well as how many you answered correctly, which is why the second module you are routed into matters. College Board publishes no fixed ceiling for the lower-difficulty module, so treat any figure quoted elsewhere as invented.
