The SAT is now fully digital, and it works quite differently from the paper test many of us remember. It's shorter, it's taken on a screen, and it adapts to how you perform. Understanding the format is one of the easiest ways to feel calmer on test day, so here is how it works.
The big picture: two sections, four modules
The Digital SAT has two sections, and each section is split into two modules.
- Reading & Writing: 54 questions in 64 minutes, split into 2 modules of 27 questions.
- Math: 44 questions in 70 minutes, split into 2 modules of 22 questions.
That's 98 questions and 134 minutes of testing in total, with a short break between the two sections. Each module is timed separately, so you can't carry spare time from one module to the next.
What's in each section
Reading & Writing uses short passages, usually a paragraph or less, each followed by a single question. The questions test four broad areas: Craft and Structure (vocabulary in context, text structure and purpose), Information and Ideas (understanding and using evidence), Standard English Conventions (grammar, punctuation and sentence structure) and Expression of Ideas (transitions and rhetorical goals).
Math covers Algebra, Advanced Math, Problem-Solving and Data Analysis, and Geometry and Trigonometry. Most questions are multiple choice, and some are student-produced response, where you type in your own answer instead of choosing one.
Adaptive testing, explained
The Digital SAT is section-adaptive. In each section, how you do in the first module decides how difficult your second module will be:
- Do well in Module 1, and Module 2 will have harder questions.
- Do less well in Module 1, and Module 2 will have easier questions.
This happens separately for each section, so your Reading & Writing result doesn't change your Math module, and the other way around.
Two practical things follow from this:
- Module 1 matters. It sets up the rest of the section, so treat it with care and don't rush through it.
- A harder Module 2 isn't bad news. It's a sign the test is giving you a chance at the higher part of the score range. Don't panic if the second module feels tough.
A few questions in each module are also unscored trial questions used by the College Board to test future questions. You can't tell which ones they are, so just give every question your best effort.
How scoring works
Your total score is between 400 and 1600. It's the sum of two section scores, each between 200 and 800: one for Reading & Writing and one for Math.
Because the test is adaptive, your score isn't simply a count of right answers. It depends on how many questions you got right and on how difficult the questions you saw were. That's why two students with the same number of correct answers can get different scores.
Calculator and other tools
- Desmos calculator: a graphing calculator is built into the testing app, and you can use it on the entire Math section. You can also bring an approved calculator of your own.
- Reference sheet: Math has a built-in reference sheet with common formulas.
- Flag and review: you can flag questions and move back and forth within a module, but once a module ends you can't return to it.
- Annotation: a highlight and notes tool is available for Reading & Writing passages.
Practise with the Desmos calculator before test day. It can solve many problems very quickly, but only if you already know how to use it.
Study tips that fit the format
- Practise in modules. Do timed sets of 27 and 22 questions, not just open-ended practice, so the pacing feels natural.
- Warm up daily. A few minutes of practice a day beats one long session a week.
- Review every mistake. Redo the questions you got wrong a few days later. If you can solve them again without help, you've really learned them.
- Take full practice tests. At least a few times before the real thing, under real timing, so the whole 134 minutes feels familiar.
