SAT Mathematics Objectives

The Level 1 SAT mathematics subject test is for students who've completed at least three years of college-prep mathematics, including one year of geometry and two of algebra. Students interested in pursuing STEM (science, technology, engineering, and mathematics) or economics degree programs in college sometimes use the math test to help their applications stand out.

In all, you'll answer about 50 questions, all multiple choice. Geometry and measurement questions represent about 38%-42% of the total exam. You may encounter questions on plane Euclidean geometry, coordinate geometry, trigonometry, and 3-dimensional geometry.
