SAT Math Prep — Final Review

SAT Math · Axiom Academy

One last pass over everything before the full-length practice tests and test day. The SAT Math section is built from four domains. Knowing roughly how each is weighted tells you where your study time pays off most. Linear equations and inequalities in one and two variables Systems of equations (substitution, elimination, no/infinite solutions) Slope-intercept form: y = mx + b ; slope m = x_2 - x_1 Passport to Advanced Math ~35% Quadratics: factoring, the quadratic formula x = -b 2a , and vertex form y = a(x-h)^2 + k The discriminant b^2 - 4ac : positive → 2 real roots, zero → 1, negative → 0 Polynomials, exponential growth/decay y = a b^ x , and function notation Problem Solving & Data Analysis ~15% Ratios, rates, proportions, and unit conversion Percent change: - 100\% ; back-to-back percents multiply Mean, median, mode, spread; reading tables, scatterplots, and lines of best fit Area, volume, angle relationships, similar triangles Pythagorean theorem a^2 + b^2 = c^2 and special right triangles ( 45 45 90 : x:x:x 2 ; 30 60 90 : x:x 3:2x ) Circle equation (x-h)^2 + (y-k)^2 = r^2 and SOH-CAH-TOA What the Test Gives You (and What It Doesn't) The Digital SAT shows a reference sheet with these — you don't need to memorize them, but you do need to know when to use them: NOT given — you must know these cold: the slope and quadratic formulas, percent change, the discriminant, vertex form, the distance and midpoint formulas, and SOH-CAH-TOA.
