The digital SAT Math section tests 23 subtopics across 4 domains. Knowing exactly what's tested — and how much each domain counts — is the first step to an efficient study plan. Below is every topic, with study priority ratings based on how frequently each appears on the test.
Priority guide: 🔴 High priority — appears frequently, high point value. 🟡 Medium priority — appears regularly. ⬜ Lower priority — fewer questions, but don't ignore completely.
Domain 1 — Algebra
~35% of test · ~15 questions
Linear Equations in One Variable
Solving for x, rearranging equations, word problems
If you're targeting 600+, focus almost entirely on Algebra and ensure you can handle Easy and Medium questions across all 6 subtopics. This alone will dramatically improve your score.
If you're targeting 700+, you need solid coverage of Advanced Math too — especially Quadratic Equations, Quadratic Functions, and Exponential Functions. These three subtopics are extremely common in the harder module.
If you're targeting 750+, you cannot leave any domain weak. Every missed Geometry or Statistics question at this level costs significantly. Make sure Right Triangle Trig and Circle Equations are solid.
Tip: The SAT provides a formula sheet at the start of the Math section covering basic geometry formulas (area of circle, volume of cylinder, etc.). You don't need to memorise these — but you do need to know when to use them.
