What Subjects Are On The Act

What Subjects Are on the ACT: A Complete Guide to Each Test Section

The ACT is one of the most widely accepted college entrance exams in the United States, taken by millions of high school students each year. Consider this: the test evaluates your academic abilities across multiple disciplines that reflect the skills needed for success in higher education. On the flip side, if you're planning to apply to colleges and universities, understanding what subjects are on the ACT is essential for effective preparation. This full breakdown breaks down every subject area tested on the ACT, including the optional writing section, so you know exactly what to expect on test day.

What Is the ACT Test?

The ACT, which stands for American College Test, is a standardized exam designed to assess high school students' readiness for college-level work. Unlike other tests that might focus primarily on verbal or quantitative skills, the ACT takes a broader approach by evaluating students across four core subject areas plus an optional essay. Colleges and universities use ACT scores as one factor in their admissions decisions, along with your high school GPA, extracurricular activities, and other application materials.

The test is administered multiple times throughout the year, typically on Saturdays, and can be taken as many times as you wish. In real terms, most students take the ACT during their junior year of high school, giving them ample time to retake if needed. Understanding the structure and content of each section will help you create a targeted study plan and approach test day with confidence.

English Test

The ACT English test is the first section you'll encounter when you begin the exam. This section measures your understanding of written English and your ability to edit and improve written passages. You'll have 45 minutes to answer 75 multiple-choice questions, which means you'll need to work quickly and efficiently.

Let's talk about the English test focuses on three main skill areas. Practically speaking, these questions ask you to determine which additions, deletions, or changes would best improve the passage. You'll need to recognize when language is appropriate for the intended audience and purpose. Second, knowledge of language questions evaluate your understanding of word choice, tone, and style. First, production of writing questions assess your ability to organize, develop, and revise text to support the writer's goals. Third, conventions of standard English questions test your knowledge of grammar, punctuation, and sentence structure. This includes subject-verb agreement, verb tense, pronoun usage, comma placement, and semicolon usage, among other rules.

You'll answer questions based on five passages, each accompanied by a set of questions. The passages cover various topics and writing styles, from personal narratives to argumentative essays. Developing strong reading comprehension skills and a solid foundation in English grammar will help you succeed in this section.

Mathematics Test

The ACT Mathematics test evaluates your mathematical skills and problem-solving abilities across a wide range of topics. This section consists of 60 questions that you must complete within 60 minutes, giving you exactly one minute per question on average.

The math test covers several content areas, each representing a different percentage of the questions. Pre-algebra makes up about 20% of the test and includes basic operations, integers, fractions, decimals, exponents, and basic probability. Elementary algebra accounts for approximately 15% of questions and covers variables, expressions, linear equations, and quadratic equations. Intermediate algebra represents about 15% of the test and includes more complex equations, functions, matrices, and roots.

Coordinate geometry and plane geometry together make up approximately 35% of the test. Coordinate geometry includes points, lines, slopes, and graphing, while plane geometry covers angles, triangles, circles, polygons, and three-dimensional figures. Finally, trigonometry comprises about 10% of the questions and includes trigonometric functions, identities, and graphs.

You're allowed to use a calculator on this section, but it must be an approved model. Familiarizing yourself with your calculator's capabilities and practicing efficient problem-solving strategies will help you manage the time pressure effectively.

Reading Test

The ACT Reading test assesses your ability to read comprehension and extract meaning from written passages. This section includes 40 questions that must be answered in 35 minutes, based on four passages representing different content areas.

The reading passages are drawn from four main categories. Prose fiction passages come from short stories, novels, and other literary narratives, requiring you to understand character development, plot, and literary techniques. In practice, Social studies passages cover topics like history, sociology, and political science, testing your ability to follow complex arguments and understand cause-and-effect relationships. Humanities passages include material from art, music, literature, philosophy, and cultural studies. Natural sciences passages present information from biology, chemistry, physics, and other scientific fields.

Questions on the reading test fall into several categories. Practically speaking, Big picture questions test your understanding of the overall purpose, main idea, or organization of the passage. Key detail questions ask you to identify specific information explicitly stated in the passages. Also, Vocabulary in context questions ask you to determine the meaning of words or phrases based on how they're used in the passage. Inference questions require you to draw logical conclusions based on evidence in the text. Developing strong reading strategies, such as actively annotating passages and managing your time effectively, will help you handle this section successfully.

Science Test

The ACT Science test evaluates your scientific reasoning and data interpretation skills rather than your memorization of scientific facts. This section includes 40 questions to be completed in 35 minutes, based on seven passages presenting scientific information in various formats.

The science test covers three main content areas. Now, Chemistry content includes matter, chemical reactions, acids and bases, and thermodynamics. Physics covers mechanics, electricity, magnetism, waves, and optics. In real terms, Biology questions may include topics like cell structure, genetics, evolution, and ecosystems. Earth and space sciences topics like geology, meteorology, and astronomy may also appear.

The questions themselves focus on several skill types. Data representation questions ask you to interpret graphs, tables, and figures. Research summary questions require you to understand and evaluate scientific experiments, including the methods, results, and conclusions. Conflicting viewpoints questions present two or more scientific theories or interpretations and ask you to compare and analyze them.

You don't need to have taken advanced science courses to do well on this section. The test emphasizes reasoning and critical thinking rather than memorized knowledge. Practicing with sample science passages and developing strong data interpretation skills will serve you well.

Writing Test (Optional)

The ACT Writing test is an optional essay section that adds an additional 40 minutes to your test session. While not required by all colleges, some institutions recommend or require the writing section, so check the requirements of the schools you're applying to before deciding whether to take it.

The writing test presents a complex issue with three different perspectives. You're asked to analyze and evaluate these perspectives and develop your own argument on the issue. Your essay should demonstrate your ability to develop a clear thesis, support your position with reasoning and examples, organize your thoughts logically, and use effective language.

The essay is scored on four domains: ideas and analysis, development and support, organization, and language use and conventions. Each domain receives a score from 1 to 6, and these scores are combined to produce your writing subscore. Even if you choose not to take the writing section, your other scores remain valid and can be submitted to colleges.

How the ACT Is Scored

Understanding the scoring structure can help you set realistic goals for your ACT performance. Each of the four required sections (English, Math, Reading, and Science) is scored on a scale of 1 to 36. These four scores are averaged to produce your composite score, which is the score most colleges consider when evaluating your application.

The optional Writing test is scored separately on a scale of 1 to 12. This score does not affect your composite score but will appear separately on your score report. When you register for the ACT, you can choose whether to include the writing section, so make this decision based on the requirements of your target colleges.

Preparing for Each Subject

Effective preparation for the ACT requires understanding both the content and the format of each section. Create a study schedule that allocates time for each subject based on your strengths and weaknesses. Take practice tests under timed conditions to build your stamina and identify areas where you need improvement. Review the explanations for questions you get wrong to deepen your understanding of the material.

Remember that the ACT is designed to be challenging, but with thorough preparation and a clear understanding of what subjects are on the ACT, you can approach test day with confidence and perform to the best of your abilities.
