What to expect on the ACT

The ACT most people describe from memory, four required sections including Science, is out of date. The 2025 Enhanced ACT restructured the test: three required sections, an optional fourth, and a shorter overall sitting. Here's exactly what happens now, in order.

English

50 questions in 35 minutes. Short passages with underlined portions, you pick the best fix, or decide no fix is needed at all.

• ~42 seconds per question, the tightest pacing budget on the whole test.
• Covers three areas: Conventions of Standard English (grammar and punctuation rules), Production of Writing (organization, transitions, adding or cutting content), and Knowledge of Language (word choice, tone, concision).
• No separate grammar rulebook to memorize beyond the rules themselves, this section rewards knowing the rule instantly, not reasoning it out.

• Read a full sentence, not just the underlined part. A grammatically correct phrase in isolation can still be wrong once you see how it connects to the sentence around it.
• "NO CHANGE" is correct roughly a quarter of the time. Don't talk yourself into fixing something that isn't broken just because it's an answer choice.
• For "which choice best..." questions about tone or organization, reread the surrounding sentences quickly rather than relying on a gut feel, the answer usually hinges on one nearby detail.
• Skip a question you're stuck on after ten seconds and come back. At 42 seconds a question, one stall costs you two other questions' worth of time.

Math

45 questions in 50 minutes.

• ~67 seconds per question, more breathing room than English.
• A calculator is permitted for the entire section, on an approved-calculator list the ACT publishes.
• All multiple choice, no student-produced response questions like the SAT has.
• Covers Pre-Algebra and Elementary Algebra, Intermediate Algebra and Functions, and Plane Geometry and Trigonometry.

Learn more: where the time actually goes

• Questions get harder as the section goes on, roughly. The first third is usually faster than the last third, budget your time accordingly rather than spending evenly.
• Skip the calculator for simple arithmetic. Typing into a calculator costs a few seconds every time, and those seconds add up over 45 questions.
• Plug in answer choices on algebra questions that look messy to set up. Starting from choice B or C and testing tells you which direction to go if it's wrong.
• No penalty for guessing, so never leave a question blank. A guess has better odds than a blank.

Reading

36 questions in 40 minutes, drawn from four shorter passage sets.

• ~67 seconds per question, though the real cost is reading the passage itself, budget more like 8 to 9 minutes per passage set including reading time.
• Passage types: Literary Narrative, Social Science, Humanities, and Natural Science. Every test has one of each.
• Every answer is directly supportable from the text, this section rewards evidence-finding over outside knowledge.

Learn more: reading fast without missing the answer

• Skim for structure before reading closely: what's the passage about, how is it organized, where do the ideas shift. That map makes it much faster to locate evidence once you're in the questions.
• Line-reference questions are the fastest points. Go straight to the cited line and read a sentence above and below it for context before answering.
• "Main idea" or "author's purpose" questions reward the big picture over any one detail, don't get pulled into re-reading a single paragraph looking for a technicality.
• Order your passages by comfort if one genre reliably slows you down. You're allowed to do the passage sets in whatever order you want within the section.

Science (optional)

40 questions in 40 minutes if you take it. It's no longer required and no longer part of your composite, but it's still offered and still reported as its own score.

• ~60 seconds per question.
• Data representation, research summaries, and conflicting-viewpoints passages: mostly graph-reading and experimental-design reasoning, not memorized science content.
• Take it if a target school or scholarship still asks for a Science score, particularly common in STEM-focused programs, or if you simply want the extra data point. Otherwise it's fully skippable.

Timing cheat sheet

• English, 50 questions, 35 minutes
• Math, 45 questions, 50 minutes
• Short break
• Reading, 36 questions, 40 minutes
• Science (optional), 40 questions, 40 minutes

Without Science, total testing time is a little under two hours. With it, closer to two and a half.

Day-of test prep: what to do

This part is based on ACT's own published test-day rules and isn't about studying, it's about not losing points to something avoidable.

The night before

• Get a full night's sleep. It matters more than any last-minute review session.
• Confirm your test center address and reporting time on your admission ticket.
• Lay out everything you're bringing so the morning isn't a scramble.

Morning of

• Eat a real breakfast, something familiar, not a new food that might not sit right.
• Arrive by your assigned reporting time. Check-in itself takes time, and your ID gets checked at the door.
• Bring a snack and water for the break between sections.

Rules and reporting times can vary by test center and change over time, always check your own admission ticket and ACT's official test-day page before you go.
