The Digital SAT takes 2 hours 14 minutes, with a Reading and Writing section and a Math section, each split into two adaptive modules. This guide explains how the modules work, what each section tests and how to plan your preparation.
The SAT is now taken on a computer or tablet using the College Board's Bluebook app. It is shorter than the old paper test and has a different structure, so older preparation books can be misleading.
The structure at a glance
The test has two sections, each divided into two modules:
- Reading and Writing: 54 questions in two 32-minute modules (64 minutes in total).
- Math: 44 questions in two 35-minute modules (70 minutes in total).
With a 10-minute break between the sections, the whole test takes about 2 hours 14 minutes. Scores are reported from 400 to 1600, with 200 to 800 for each section.
How adaptive modules work
The Digital SAT is adaptive by module, not by question. In each section, everyone takes a first module with a mix of easier and harder questions. Your performance on that module decides whether your second module is generally easier or harder. A harder second module allows access to higher scores.
What this means for you:
- Every question in the first module matters, because it sets up the second module.
- Do not panic if the second module feels difficult — that can be a good sign.
- You can move back and forth within a module and use Mark for Review, but you cannot return to a module after it ends.
Reading and Writing: short passages, one question each
Each question has its own short passage — sometimes a pair of passages, a table or a graph. The questions fall into four areas:
- Craft and Structure — words in context, text structure and purpose, connections between two texts.
- Information and Ideas — central ideas, using evidence from text or data, inferences.
- Standard English Conventions — punctuation, sentence boundaries and grammar. See the 24 SAT grammar rule cards.
- Expression of Ideas — transitions and rhetorical synthesis (using notes to achieve a goal).
Because passages are short, success depends on precise reading and strong vocabulary rather than reading speed alone.
Math: calculator allowed throughout
The Math section covers four areas: Algebra, Advanced Math, Problem-Solving and Data Analysis, and Geometry and Trigonometry. A graphing calculator (Desmos) is built into the app and can be used on every question, and you may also bring an approved calculator.
About a quarter of Math questions are student-produced responses: you type your own answer instead of choosing. Fractions and decimals are accepted in specific formats — for example, 7/2 or 3.5 — but mixed numbers such as 3 1/2 are not. The AUSLEX Math practice checks your typed answers using these rules.
A preparation plan
- Take an official practice test in Bluebook to find your starting point.
- Learn the vocabulary of the test: the maths terms in English and the academic words used in Reading and Writing questions. The SAT dictionary explains them in eight languages.
- Fix grammar rules with the rule cards — they are among the most learnable points.
- Practise by question type, then by timed module using the timed modules.
- Review every mistake: was it vocabulary, a rule, a careless error or time pressure?
