The ACT Math Test assesses the mathematical skills students are expected to obtain before grade 12 (meaning through advanced algebra and basic trigonometry, but not calculus).

- It’s the second section of the ACT
- You have a 60-minute time limit
- You will face 60 multiple choice questions
- You get to use a calculator for the whole test (but it must be an approved one)

- Geometry formulas for the area, volume, and surface area of basic shapes (unlike the SAT, the ACT won’t give you these!)

- Multiple-choice math test strategies such as “backsolving” the problem using the answer choices, substituting in numbers, and estimating.

- Pre-Algebra
- decimals, fractions, integers, positive and negative numbers, square roots, scientific notation, factors, ratios, proportions, percents, charts and graphs of statistics
- Elementary Algebra
- exponents, evaluating algebraic expressions through substitution, using variables to express relationships, algebraic operations, and factoring quadratic equations
- Intermediate Algebra
- quadratic formula, rational and radical expressions, absolute value equations and inequalities, sequences and series, systems of equations, quadratic inequalities, functions, matrices, roots of polynomials, probability, and complex numbers
- Coordinate Geometry
- evaluating points and lines on a graph, polynomials, circles and other curves, graphing inequalities, slope, parallel and perpendicular lines, distance, midpoints, and conics
- Plane Geometry
- angles and relationships among perpendicular and parallel lines, properties of circles, ellipses, rectangles, triangles, parallelograms, trapezoids, transformations, area, volume, three-dimensional geometry
- Trigonometry (on a very basic level)
- trigonometric relations in right angles, values and properties of trig functions, graphing trig functions, using trig identities, solving trig equations

- Trigonometry beyond the very basics. However, you should know:
- SOH-CAH-TOA
- how to solve right triangles
- the unit circle
- tan θ = sin θ / cos θ
- sin^2 θ + cos^2 θ = 1
- what sine, cosine, and tangent graphs look like
