ACT® Sections and Test Format
The ACT® is a standardized test used by many U.S. colleges and universities as part of the admissions process for undergraduate college programs. In order to get started with your test prep, it is important to first familiarize yourself with how the ACT is structured. Read this comprehensive guide to know everything about the ACT format, sections, duration, question types, and more
How Is the ACT Structured?
The ACT test consists of four compulsory sections plus one optional section: English, Math, Reading, Science, and Writing (optional), lasting for 2 hours 55 minutes (3 hours 35 minutes if you take the Writing section). There are a total of 215 questions on the ACT test. All the questions on the ACT are multiple-choice, and the optional writing section comprises one long essay question.
How is each section scored on the ACT?
Each section of the ACT—English, Math, Reading, and Science is graded separately. One point is awarded for each correct answer, and you don’t lose points for wrong answers or unanswered questions. Once the entire test is scored, the four section scores are averaged to create your ACT final score, ranging from 1-36. Note that the optional essay section score highlights your writing and critical thinking abilities but does not contribute to your final ACT score in any way.
How many versions of the ACT test are there?
The ACT test is available in two versions: paper and online/digital. While the majority of US students take the paper ACT, the online test known as the ACT Computer-Based Test (CBT) is the only version of the ACT available for international students. The paper ACT and CBT are the exact same tests - same sections, duration, types, number of questions, and scoring system. The only difference between the two versions is how these tests are administered. Note that you cannot take the CBT from home on your computer. It needs to be taken at school or a testing center.
|ACT Test Version
|US students on national test dates
|US students on a school day
|May vary depending on state/district
|International students (outside US)

Note that you are allowed to use a calculator on the math test.
The following are the math categories that you will find in this section:

ACT Writing Format
The ACT Writing section does not affect your total ACT score. It is scored separately by two graders on a scale of 2–12. In this section, you will be given a passage to read and asked to write an essay to express your opinions on the central theme in 40 minutes. You will be assessed on your understanding of the author’s viewpoints and opinions and your ability to build your essay around them.
