SAT • ORIGINAL PRACTICE LIBRARY
Practice by domain, then by topic.
The library is organized around the four Digital SAT Math content domains, then divided into focused topic sets that move from foundation to challenge.
01
ALGEBRA
Linear equations, inequalities, linear models, coordinate relationships and algebraic applications.
Explore Algebra → 02ADVANCED MATH
Quadratics, nonlinear equations, exponential models, polynomials, functions and transformations.
Explore Advanced Math → 03GEOMETRY & TRIGONOMETRY
Lines, angles, triangles, similarity, circles, area, surface area, volume and related applications.
Explore Geometry & Trigonometry → 04PROBLEM SOLVING & DATA ANALYSIS
Ratios, rates, percentages, probability, statistics, sampling, inference and data modeling.
Explore PSDA →HOW TO USE THE LIBRARY
Work first. Check later.
The practice files are designed to be solved without an answer key beside the question.
When the website answer-check pages are added, the intent is to connect each answer to the reasoning and common failure point, not only to a letter or number.
Some sets use diagrams, graphs, tables or visual models where the mathematics is better understood visually than through text alone.
