What's inside

Every skill on the ACT, one lesson each

Algebra & Functions

The biggest share of ACT Math: percents and rates, equations, lines, quadratics, functions and exponents. Learn the fast way and the backup way for each.

  1. 1. Percents, Ratios & RatesPercent change, ratios that scale, and rates with units that cancel. The everyday math behind a fifth of the test.
  2. 2. Linear Equations & SystemsSolve for x, solve for two unknowns, and know when to skip the algebra and backsolve from the answers.
  3. 3. Lines & Linear ModelsSlope as a rate, intercepts as starting values, and parallel and perpendicular lines without memorizing a single new formula.
  4. 4. Quadratics & PolynomialsFactor, find the vertex, read the roots off a graph, and use the discriminant to count solutions.
  5. 5. Functions & Transformationsf(x) notation, plugging functions into functions, and what shifts, stretches and flips do to a graph.
  6. 6. Exponents, Sequences & GrowthExponent and radical rules, sequences, and exponential growth and decay.
  7. 7. Number Sense, Complex Numbers & MatricesFactors and fractions, absolute value, and the i² and matrix questions that look scary but take three steps.

Geometry, Trig & Data

Triangles, circles, coordinate geometry and trig, plus the statistics, probability and multi-step word problems that round out the test.

  1. 1. Angles & TrianglesAngle rules, similar triangles, the Pythagorean theorem and the two special right triangles worth knowing cold.
  2. 2. Circles, Area & VolumeArc length and sectors as fractions of a circle, areas of combined shapes, and volume of the solids the ACT uses.
  3. 3. Coordinate GeometryDistance, midpoint, circle equations and shapes on the coordinate plane. Sketch it first, every time.
  4. 4. TrigonometrySOHCAHTOA, then the unit circle, radians and the trig graphs. The ACT asks a few of these every test.
  5. 5. Statistics & DataMean, median, range and spread, plus reading tables, dot plots, box plots and scatterplots.
  6. 6. Probability & CountingProbability as a fraction, two-way tables and and/or rules, and counting arrangements without listing them all.
  7. 7. Multi-Step Word ProblemsLonger real-world problems. Circle what they ask, write down what you know, and take it one step at a time.
