GuidesSAT Math
Find the exact Math skill you need to fix, then practice it. SAT Math rewards recognising which relationship a question is testing far more than it rewards memorised formulas, so every guide here teaches the idea first, shows the traps, and ends with practice.
If you are not sure where to start, begin with the formulas guide to see what Bluebook already gives you, then work through the algebra guides in order: linear equations and systems are the foundation for everything that follows. Advanced Math and Problem-Solving guides build on those, and the geometry guides are shorter because the test asks fewer of those questions.
Master linear equations for Digital SAT Math: one-variable equations, variables on both sides, parameters, word problems, traps, Desmos checks, and original practice.
Learn SAT systems of equations with substitution, elimination, graphing, no/infinite solutions, word problems, Desmos strategy, and original practice.
Master SAT linear inequalities: solving, flipping signs, interval/graph interpretation, systems of inequalities, word problems, and original practice.
Master Digital SAT quadratics: factoring, roots, quadratic formula, discriminant, vertex form, graph interpretation, Desmos strategy, and original practice.
Master Digital SAT functions: f(x), evaluating functions, domain/range, graphs, transformations, linear/exponential/quadratic models, and original practice.
Master SAT polynomials: factoring, equivalent expressions, roots, difference of squares, structure and original Advanced Math practice.
Master SAT exponential growth and decay: percent change, growth factors, decay factors, equations, tables and original practice.
Master SAT exponent rules, fractional exponents, radicals, negative powers, simplifying expressions and original practice questions.
Master SAT rational equations: algebraic fractions, common denominators, excluded values, proportional equations and extraneous solutions.
Master SAT percentage questions: percent of a number, percent increase/decrease, reverse percentages, multipliers, repeated change, traps, and original practice.
Master SAT ratios, proportions, rates, unit conversions, dimensional analysis, scale problems and original practice.
Master SAT probability and statistics: two-way tables, conditional probability, mean/median, standard deviation, sampling, margin of error, and practice.
Master SAT scatterplots, lines of best fit, correlation, residuals, interpolation, extrapolation and model interpretation with original practice.
Master SAT margin of error, random samples, population inference, sample size and evaluating statistical claims with original practice.
Learn Digital SAT circle problems: standard equation, center/radius, completing the square, arc length, sector area, tangents, radians, and original practice.
Master SAT right-triangle trigonometry: sine, cosine, tangent, 30-60-90 and 45-45-90 triangles, similarity, applications, and original practice.
Learn high-value Desmos strategies for Digital SAT Math: intersections, roots, systems, regressions, tables, checking algebra, and when hand math is faster.
Learn the current SAT calculator rules, the new non-CAS requirement, Bluebook Desmos options, prohibited devices and when a handheld calculator is worth bringing.
Getting one SAT question right is not the same as learning the skill. Use delayed review, fresh questions, explanation and timed practice to test real mastery.
Fixing an SAT mistake once is not enough. Learn why weak skills should return later through spaced review and fresh questions.
Practice tests measure readiness, but they do not automatically fix weaknesses. Learn how to combine full tests with targeted repair and retrieval practice.
