Choosing between the ACT and SAT — or preparing for both — starts with understanding how their math sections differ.
Format Differences
The SAT Math section has 44 questions across 2 adaptive modules (70 minutes total). The ACT Math section has 60 questions in 1 non-adaptive section (60 minutes). This means the ACT is significantly more time-pressured: about 1 minute per question vs 1.6 minutes on the SAT.
Content Overlap
About 70% of the math content is identical between the two exams. Both test algebra, geometry, statistics, and advanced math. However, each exam has unique topics.
Topics Only on the ACT
- Logarithms: properties, equations, and graphs
- Matrices: basic operations and multiplication
- Vectors: addition, subtraction, magnitude
- Complex numbers: operations with , conjugates
- Permutations and combinations: counting principles
- Sequences: arithmetic and geometric formulas
- Geometric transformations: rotations, reflections, dilations
Topics Emphasized More on the SAT
- Passport to Advanced Math: heavy focus on quadratics, polynomials
- Statistical inference: margin of error, confidence intervals
- Multi-step word problems: more complex real-world scenarios
- Grid-in questions: student-produced responses (no multiple choice)
Which Test Is Better for You?
Choose the SAT if you:
- Prefer more time per question
- Are strong in algebra and word problems
- Like adaptive testing (questions adjust to your level)
Choose the ACT if you:
- Work quickly and accurately
- Are comfortable with a wider range of topics
- Prefer straightforward calculations over complex word problems
Preparing for Both
If you are taking both exams, focus first on the shared content (70% overlap), then add ACT-specific topics like logarithms, matrices, and permutations. NovaMaths covers both exams with 79 SAT lessons and 16 ACT-only lessons.
Pro Tip
Take a full practice test for each exam under timed conditions. Compare your scores. Most students score significantly better on one test — focus your preparation there. The exams are accepted equally by all US colleges.
