SAT vs. ACT Comparison Chart The SAT and ACT are two very different college entrance exams. Both are nationally administered and are used to help colleges evaluate applicants. The SAT is essentially a threepart aptitude test (Reading, Math, Writing) while the ACT is more of an achievement test with four core sections (English, Math, Reading, Science) and an optional Writing section. Many colleges will accept either test or both exams. Some colleges require one (typically the SAT) . The chart below will help you understand the structure and content of the SAT and ACT. | | SAT | ACT | | --- | --- | --- | | Length | 3 hours, 45 minutes | 3 hours, 25 minutes (includes 30-minute Writing Test) | | Sections | 10 Sections: 3 Critical Reading, 3 Math, 3 Writing (including Essay) | 5 Sections: English, Math, Reading, Science, and Writing (optional) | | What content
is on the test? | Math: Numbers, Operations, Algebra I, Algebra II, Functions, Geometry, Probability, Statistics, Data Analysis
Critical Reading: Sentence Completion, Short and Long Reading Passages from Natural Science, Humanities, Social Science, and Literary Fiction (measuring extended reasoning, literal comprehension, and vocabulary in context)
Writing: Identifying Errors, Improving Sentences and Paragraphs, Student Written Essay measuring ability to communicate a viewpoint, define and support a position. | Math: Pre-Algebra, Algebra I, Algebra II, Coordinate Geometry, Plane Geometry, and Trigonometry
Reading: Social Studies and Natural Science Reading Passage, Arts/Literature Reading Skills, Prose Fiction and Humanities Passage
English: Usage and Mechanics, Grammar, Identifying Errors, Rhetorical Skills, Sentence Improvement, Paragraph Improvement
Science: This is a glorified reading passage section. This does NOT test any science knowledge. Data representation, research summaries, science reading passages on conflicting viewpoints.

How do the SAT and ACT differ in overall test structure?

The SAT uses a three-part structure: Critical Reading, Math, and Writing. The ACT uses four core sections—English, Math, Reading, Science—with an optional Writing test.

What topics are tested within the SAT and ACT sections?

SAT’s Math covers numbers, operations, algebra, functions, geometry, probability, statistics, and data analysis, while Critical Reading includes sentence completion and reading passages; Writing focuses on sentence/paragraph improvement and an essay. ACT’s Math includes pre-algebra through trigonometry, Reading covers social studies/natural science and literature/prose passages, English covers usage/mechanics and grammar, and Science is reading-based rather than requiring science knowledge.

How do scoring and penalties compare between the two exams?

The SAT reports an aggregate 600–2400 score from three components and separately scores the essay 0–12. The ACT reports a composite 1–36 from four sections and scores the optional essay 0–12. The SAT deducts 1/4 point for wrong answers, while the ACT has no penalties for incorrect answers.
