Maths study guides

A deep-dive guide to the Digital SAT Advanced Math domain: rewriting equivalent expressions, solving nonlinear equations (quadratic, radical, exponential), reading quadratic graphs, distinguishing linear from exponential growth, interpreting nonlinear functions, and solving line-and-parabola systems, with Desmos throughout.

A deep-dive guide to the Digital SAT Algebra domain: linear equations in one and two variables, linear functions and slope as a rate of change, solving systems by substitution, elimination and graphing, linear inequalities and the sign-flip rule, and how to use Desmos across all of it.

A deep-dive guide to the Digital SAT Geometry and Trigonometry domain: area and volume, lines and angles and triangles, right triangles with the Pythagorean theorem and SOH-CAH-TOA, special right triangles, circles and arcs, radians, and circle equations in the coordinate plane.

A deep-dive guide to the Digital SAT Math format: the two timed modules and 44 questions in 70 minutes, the multistage adaptive routing, the built-in Desmos calculator, student-produced response entry, the reference sheet, and the pacing and test-day strategy that follow from the structure.

A deep-dive guide to the Digital SAT Problem-Solving and Data Analysis domain: ratios, rates and proportions, percentages and percent change, one-variable statistics (center, spread, outliers, sampling and margin of error), two-variable data and lines of best fit, and probability including conditional probability.
