The mathematics portion of the ACT covers mathematical subjects found in courses up to the 12th grade level. This portion is designed to test mathematics skills that students have typically learned at the time of test.
The ACT mathematics test requires students to know basic mathematical formulas typically learned through previous math classes up to the time of the test. The mathematics section is broken into three sub scores in six key skill areas: pre-algebra, elementary algebra, intermediate algebra, coordinate geometry and plane geometry, in addition to trigonometry.
While individual test questions vary, each of the six content areas make up a certain percentage of the mathematics portion. Pre-algebra and plane geometry make up the largest portion, while there are very few questions pertaining to trigonometry. Questions requiring the use of elementary algebra, intermediate algebra and coordinate geometry skills make up the remaining questions.
