# ACT — Definition & Explanation > From the SchoolBrowse Education Glossary. > HTML version: https://schoolbrowse.com/glossary/act **In short:** A standardized college admissions test measuring English, math, reading, and science reasoning, with an optional writing section. The **ACT** is a standardized test used for college admissions in the United States. It assesses high school students' general educational development and ability to complete college-level work through four subject tests: English, Math, Reading, and Science. ## Test Format The ACT includes four multiple-choice sections: English (75 questions, 45 minutes), Math (60 questions, 60 minutes), Reading (40 questions, 35 minutes), and Science (40 questions, 35 minutes). An optional Writing section adds 40 minutes. Composite scores range from 1-36. ## ACT vs. SAT The ACT features a Science section, more straightforward questions, and tighter time constraints. The SAT emphasizes vocabulary in context and provides more time per question. Colleges accept both equally; students should try practice tests of each to determine which fits their strengths. ## Frequently asked questions **Q: What is a good ACT score?** The national average is about 20-21. Competitive colleges often look for 28+, while highly selective schools typically expect 32+. **Q: Is the ACT harder than the SAT?** Neither is inherently harder. The ACT has more questions and tighter timing but more straightforward questions. The SAT has more complex questions but more time. Try both to see which suits you. **Q: How often can you take the ACT?** The ACT is offered 7 times per year at national test centers. You can take it as many times as you want. Many students take it 2-3 times. --- Source: SchoolBrowse Education Glossary (https://schoolbrowse.com/glossary).
