SAT Mathematics Objectives

The SAT Mathematics Level 1 test is intended to be taken by students who've completed at least three years of college-prep mathematics, including two years of algebra and one of geometry. Students interested in majoring in STEM (science, technology, engineering, and mathematics) and other mathematics-intense degree programs in college might use the math exam to help their applications stand out.

On the exam, you'll answer 50 multiple-choice questions. These questions will cover:

• Numbers and operations (including elementary number theory, complex numbers, matrices, ratios, and sequences) - 10%-14%
• Algebra and functions (including equations, functions, expressions, and inequalities) - 38%-42%
• Geometry and measurement (includes plane Euclidean, 3-dimensional, and coordinate geometry as well as trigonometry) - 38%-42%
• Data analysis, statistics, and probability (including least squares regression and probability) - 8%-12%
