The ACT is a standardized test many colleges use in admissions. It measures the skills students need for college-level work. The test changed in 2025, and the current version is called the Enhanced ACT.
The test has three required sections. English has 50 questions in 35 minutes and covers grammar, punctuation, and sentence structure. Math has 45 questions in 50 minutes and covers algebra, geometry, and trigonometry. Reading has 36 questions in 40 minutes and tests how well you understand and analyze passages.
Science and Writing are optional add-ons. The Science section has 40 questions in 40 minutes and tests your ability to read data, interpret experiments, and evaluate scientific claims. The Writing section is a single essay with a 40-minute limit. Because colleges differ on whether they want these scores, check each school’s policy before you register.
Each section is scored from 1 to 36. Your composite score is the average of your English, Math, and Reading scores. Science and Writing, when taken, are reported separately. There is no penalty for wrong answers, so it pays to answer every question.
To prepare, start with official ACT practice tests, which match the real exam best. Build a study schedule that gives each section fair attention. Practice under timed conditions so the pace feels familiar. After each practice test, review every mistake and study the topics behind them.
On test day, bring a valid photo ID, your admission ticket, number 2 pencils, an approved calculator, and a simple watch or timer. Arrive early, follow the proctors’ instructions, and manage your time so you reach every question.
