Don't wait until exam week to practice

Cramming right before the test feels productive but hides your real gaps. A full-length mock now diagnoses which TEKS categories you're weakest in — so you can focus your study only where it counts. Learning science is clear: retrieval practice and spaced study beat last-minute cramming. Starting earlier is the higher-scoring path.

SAT Algebra: Linear Equations and Inequalities

Linear equations and inequalities are the highest-frequency topic on Digital SAT Math (roughly 7–9 questions per test). Four solve patterns, one Desmos shortcut, and the inequality-flip trap that costs students the most points.

SAT Advanced Math: Exponentials and Nonlinear Functions

Exponent rules, the growth/decay master template y = a·b^x, and how to translate "increases by 5% per year" into a math model. Plus the extraneous-solution trap on radical equations.
