Complete ACT Study Guide 2026

The ACT is a standardized college admissions test used by universities across the United States. It evaluates skills in English, Mathematics, Reading, and Science, with an optional Writing section.

Here you'll find the exam structure, tested skills, preparation tips, and an updated ACT syllabus organized by section.

Exam structure and duration

  • The ACT consists of four multiple-choice sections completed in approximately 2 hours and 55 minutes, plus an optional 40-minute Writing section.
  • Each section is timed separately: English (45 min), Math (60 min), Reading (35 min), and Science (35 min).
  • Practicing with free ACT practice tests helps you replicate real conditions and measure your response pace.

Skills Tested on the ACT

  • English: grammar, punctuation, sentence structure, rhetorical skills, and organization of ideas.
  • Math: pre-algebra, elementary algebra, intermediate algebra, coordinate geometry, plane geometry, and trigonometry.
  • Reading: close reading, inference, main idea identification, and analysis of arguments across prose fiction, social science, humanities, and natural science passages.
  • Science: interpretation of data, scientific investigation, and evaluation of models and experimental results.

How scoring works and why results matter

The ACT is scored on a scale of 1–36 for each section, with a composite score that is the average of all four sections. Understanding your strengths and weaknesses allows you to focus your study plan effectively.

Practical study tips

  • Take timed practice tests regularly to build endurance and familiarity with the exam format.
  • Review every wrong answer with its explanation and revisit the topic in the syllabus to close knowledge gaps.
  • Track your progress by section so you can prioritize the areas that will improve your composite score the most.
  • Start with short question blocks and gradually work up to taking the full-length practice test.

ACT Syllabus by Section — 2026

Below you'll find the key topics for each ACT section with brief explanations and links to practice tests.

📐Math

Pre-Algebra & Number Properties

Master fractions, decimals, percentages, factors, multiples, and basic number properties. Build a strong foundation for all other math topics on the ACT.

Elementary Algebra

Solve linear equations, inequalities, and word problems involving one variable. Understand substitution, factoring, and basic algebraic manipulation.

Intermediate Algebra

Work with quadratic equations, systems of equations, functions, matrices, and complex numbers. Recognize patterns and apply algebraic reasoning to multi-step problems.

Coordinate Geometry

Graph lines, parabolas, and circles on the coordinate plane. Calculate slope, distance, midpoint, and understand transformations and conic sections.

Plane Geometry

Apply properties of triangles, quadrilaterals, circles, and polygons. Calculate area, perimeter, volume, and use geometric theorems to solve problems.

Trigonometry

Use sine, cosine, tangent, and their inverses. Solve right triangles, apply the unit circle, and work with trigonometric identities and equations.

Statistics & Probability

Interpret data from tables, charts, and graphs. Calculate mean, median, mode, standard deviation, and solve probability problems.

📝English

Grammar & Usage

Identify and correct errors in subject-verb agreement, pronoun usage, verb tense, and modifier placement within sentences and passages.

Punctuation

Apply correct use of commas, semicolons, colons, apostrophes, and dashes. Understand how punctuation affects meaning and clarity.

Sentence Structure

Fix run-on sentences, fragments, and misplaced modifiers. Ensure clarity and logical flow by combining and restructuring sentences effectively.

Rhetorical Skills

Evaluate the effectiveness of writing strategies, transitions, and organizational choices. Determine the best way to express ideas clearly and concisely.

Style & Tone

Identify the appropriate tone, word choice, and level of formality for a given context. Eliminate wordiness and redundancy.

📖Reading

Prose Fiction / Literary Narrative

Analyze characters, plot, themes, and narrative techniques in fiction passages. Draw inferences about relationships, motivations, and tone.

Social Science

Comprehend passages about psychology, sociology, economics, and political science. Identify main ideas, supporting evidence, and cause-effect relationships.

Humanities

Interpret passages from memoirs, essays, and arts criticism. Understand the author's perspective, argument structure, and rhetorical purpose.

Natural Science

Read and analyze scientific articles and reports. Extract key findings, understand experimental methodology, and distinguish between facts and interpretations.

🔬Science

Data Representation

Interpret graphs, tables, scatterplots, and diagrams. Identify trends, make predictions, and read data accurately from various scientific visualizations.

Research Summaries

Understand experimental design, variables, controls, and procedures. Evaluate the purpose and results of described experiments.

Conflicting Viewpoints

Compare and contrast multiple scientific hypotheses or theories. Identify where viewpoints agree, disagree, and what evidence supports each position.
