About SAT Math

The SAT Math section is the math half of the digital SAT. It is 70 minutes long with 44 questions, split into two equal modules of 22 questions and 35 minutes each. That works out to roughly 95 seconds per question. About 75% of the questions are multiple choice with four options, and 25% are student-produced response (grid-in) questions where you type your own answer.

A calculator is allowed on the entire section. The Bluebook app includes a built-in Desmos graphing calculator, but you can also bring an approved physical calculator. Many problems are still faster to solve with mental math or pencil-and-paper, so do not over-rely on it.

The section is computer-adaptive: how you perform on Module 1 decides whether Module 2 is the harder or easier version. About 30% of questions are word problems set in real-world contexts — science, finance, statistics, and everyday situations. Every question fits into one of four official College Board domains, with Algebra and Advanced Math together carrying the most weight.

The four domains

Every question on the SAT Math section belongs to one of these four categories.

Domain 1
Algebra
Linear equations, inequalities, systems of equations, slope and lines, and modeling real-world situations with linear relationships.
~35% of the section
Domain 2
Advanced Math
Quadratic equations and parabolas, function notation, exponential growth and decay, polynomial expressions, and exponent rules.
~35% of the section
Domain 3
Problem Solving & Data Analysis
Ratios, proportions, rates, percentages, unit conversion, mean and median, scatterplots, lines of best fit, and probability.
~15% of the section
Domain 4
Geometry & Trigonometry
Area, perimeter, volume, angles, the Pythagorean theorem, similar and congruent figures, circles, and the sine/cosine/tangent ratios.
~15% of the section

Frequently asked questions

Common questions about the digital SAT Math section.

How long is the SAT Math section?

The section is 70 minutes long and has 44 questions. It is split into two equal modules of 35 minutes and 22 questions each. That works out to about 95 seconds per question.

What are the four SAT Math domains?

The four domains are Algebra, Advanced Math, Problem Solving & Data Analysis, and Geometry & Trigonometry. Algebra and Advanced Math together make up about 70% of the section, so prioritize those for the biggest score gains.

Can I use a calculator on SAT Math?

Yes. A calculator is allowed on the entire Math section. The Bluebook app includes a built-in Desmos graphing calculator, and you can also bring an approved physical calculator.

What are grid-in questions on SAT Math?

About 25% of SAT Math questions are student-produced response (grid-in) questions where you type your own answer with no multiple-choice options. Answers can be integers, decimals, or fractions, but there are strict formatting rules — learn them early.

Are formulas given on the SAT?

The Bluebook app provides a reference sheet with some geometry formulas (area of a circle, Pythagorean theorem, basic volumes). However, key formulas like slope, the quadratic formula, and exponent rules are not given — you must memorize them.

How should I study for SAT Math?

Focus your time on the two largest domains: Algebra and Advanced Math. Memorize the formulas that are not provided, then drill practice problems to apply them under time pressure. Use the Essentials, Flashcards, and Practice tools on this site, then take official Bluebook practice tests for the most accurate experience.
