The Digital SAT: Format, Scoring and a 3-Month Prep Plan
The SAT is now fully digital, taken on a laptop or tablet using the College Board's Bluebook app. It is shorter than the old paper test and adapts to your performance. Here is how it works and how to prepare in three months.
The format at a glance
| Section | Modules | Questions | Time |
|---|---|---|---|
| Reading and Writing | 2 modules | 54 | 64 minutes |
| Math | 2 modules | 44 | 70 minutes |
| Total | 98 | 2 hours 14 minutes (plus a break) |
Each section is scored from 200 to 800, giving a total from 400 to 1600.
How the adaptive test works
Each section has two modules. Your performance on the first module decides whether the second module is easier or harder. A harder second module gives access to higher scores, so the first module matters a great deal. Accuracy early on is essential.
Reading and Writing
Questions use short passages, each with one question. They test vocabulary in context, reading comprehension, grammar and punctuation, and how to improve writing. Speed comes from recognising question types and knowing the grammar rules that appear most often.
Math
The Math section covers algebra, advanced math (including quadratics and functions), problem solving and data analysis, and geometry and trigonometry. A calculator is allowed throughout, and Bluebook includes a built-in Desmos graphing calculator. Learning to use Desmos well can save significant time.
A 12-week prep plan
| Weeks | Focus |
|---|---|
| 1 | Take a full practice test in Bluebook to get a baseline score |
| 2 to 6 | Work on your weakest question types in both sections, with daily short practice |
| 7 to 10 | One full practice test every week, followed by a careful review of every mistake |
| 11 to 12 | Final practice tests, timing strategy and light review; rest before test day |
Tips that raise scores
- Use the official College Board practice tests in Bluebook; they match the real exam best.
- Keep an error log and revisit it every week.
- Never leave a question blank; there is no penalty for guessing.
- Practise with Desmos for graphing, solving systems and checking answers.

Questions parents and students ask
How long is the digital SAT?
About 2 hours and 14 minutes of testing, plus a short break between the Reading and Writing section and the Math section.
Can I use a calculator on the whole SAT Math section?
Yes. A calculator is allowed throughout the Math section, and the Bluebook app includes a built-in Desmos graphing calculator.
What is a good SAT score?
It depends on your target universities. Check the middle 50% score range published by each university you are applying to and aim for the upper half.
