TM Hog's Practice Exams for the ACT* Mathematics Test contains four complete 60-question, 60-minute sample tests for a total of 240 practice questions with answers and explanations designed to measure the mathematical skills students have typically acquired in courses taken by the end of 11th grade.
Pre-Algebra (23%): basic operations using whole numbers, decimals, fractions, and integers; place value; square roots and approximations; the concept of exponents; scientific notation; factors; ratio, proportion, and percent; linear equations in one variable; absolute value and ordering numbers by value; elementary counting techniques and simple probability; data collection, representation, and interpretation; and understanding simple descriptive statistics
Elementary Algebra (17%): properties of exponents and square roots, evaluation of algebraic expressions through substitution, using variables to express functional relationships, understanding algebraic operations, and the solution of quadratic equations by factoring
Intermediate Algebra (15%): quadratic formula, rational and radical expressions, absolute value equations and inequalities, sequences and patterns, systems of equations, quadratic inequalities, functions, modeling, matrices, roots of polynomials, and complex numbers
