The Digital SAT math section covers four domains. Each topic below has a free lesson, worked examples, and practice problems.
Linear equations, linear functions, systems, and inequalities — the foundation of SAT math.
Quadratics, exponentials, polynomials, and nonlinear systems — the higher-difficulty math section.
Ratios, percentages, statistics, and reading graphs — the most common question style on the test.
Triangles, circles, area, volume, and right-triangle trig.
The built-in Desmos calculator is the highest-leverage tool on the Digital SAT — mastering it can boost a math score by 50+ points. These lessons cover the techniques that matter on test day.
