SAT Math: The Complete Study Guide
How the digital SAT Math section is built, the four content domains it tests, and a proven plan to raise your score — with free certified practice decks.

What the digital SAT Math section actually tests
The digital SAT delivers Math in two adaptive modules. Your performance on the first module determines the difficulty of the second, so the score you earn reflects your real ceiling rather than raw stamina. Every question maps to one of four content domains, and roughly 75% of the section is multiple choice while the rest are student-produced responses (grid-ins). An on-screen graphing calculator (Desmos) is available on the entire section, which shifts the challenge away from arithmetic and toward setting the problem up correctly.
The four content domains
Know where the points live, then drill the domains that cost you the most.
Heart of Algebra
Linear equations, inequalities, systems, and linear functions — the single largest slice of the section. Fluency here is the foundation everything else builds on.
Problem-Solving & Data Analysis
Ratios, rates, percentages, unit conversion, and interpreting graphs and tables. The 'real-world' domain rewards careful reading over heavy computation.
Passport to Advanced Math
Quadratics, exponentials, polynomials, and nonlinear functions — the bridge to college-level math and the domain that most separates high scorers.
Geometry & Trigonometry
Area and volume, lines and angles, right triangles, and the unit circle. A smaller domain, but its formulas are provided, so it is highly learnable.
A study plan that actually moves your score
Diagnose, drill your weakest domain, then rehearse under the clock.
Baseline with a full timed section
Sit a complete, timed Math section so your plan targets your real per-domain gaps instead of a guess.
Drill one domain at a time
Use spaced-repetition decks for the domain that cost you the most points. Master the pattern before you chase speed.
Practice setup, not just answers
For every miss, ask whether the error was the setup or the arithmetic. On a calculator-allowed test, setup is where scores are won and lost.
Re-test and re-plan
Take another timed module; your plan reshuffles as your score climbs toward your target.
SAT Math questions
Is the whole Math section calculator-allowed now?
Yes. On the digital SAT, an on-screen Desmos graphing calculator is available for every Math question, and you may also bring your own approved calculator. Because computation is less of a barrier, the exam rewards translating a problem into the right equation or model.
Which domain should I study first?
Start with Heart of Algebra. It is the largest domain and its skills — solving linear equations, interpreting slope and intercepts, and handling systems — appear inside questions from the other domains too, so improving here lifts your whole score.
How do the free certified decks fit in?
Each SAT Math certified deck targets one domain with exam-grade questions and worked reasoning on the back of every card. Drill a deck, take a timed section, and let the results tell you which deck to run next.
