What's on the ACT?
A plain-English guide to the current ACT: the core sections, the optional Science section, how it's scored, and why it's linear rather than adaptive.
The ACT has a three-section core — English (50 questions, 35 min), Math (45, 50 min) and Reading (36, 40 min) — with Science (40, 40 min) and a Writing essay now optional. It's scored 1–36, and the Composite is the average of English, Math and Reading; Science, if taken, is reported separately. The ACT is linear (not adaptive), and the core runs about 2 hours 5 minutes.
Three core sections, plus two options
Everything but the essay is multiple choice. Here's the count and timing for each part.
| Section | Questions | Time | Status |
|---|---|---|---|
| English | 50 | 35 min | Core |
| Mathematics | 45 | 50 min | Core |
| Reading | 36 | 40 min | Core |
| Science | 40 | 40 min | Optional |
| Writing (essay) | 1 prompt | 40 min | Optional |
| Core total | 131 | ~2 h 5 m | English + Math + Reading |
Three things the format changes
The current ACT is shorter than the old one, and a couple of changes affect how you should plan.
Science doesn't count toward it.
Your headline 1–36 Composite is the average of English, Math and Reading only. Science, if you take it, is a separate score — so weigh whether you need it.
It's a fast test.
Even with more time per question than the old ACT, you move quickly — especially in English and Reading. Pace is a skill you practice, not just content.
It doesn't adapt.
Unlike the digital SAT, the ACT is fixed-form: the questions don't get harder or easier as you go, so a hard stretch doesn't mean anything changed.
See the format for yourself.
Reading about it helps; answering real-format ACT questions — and timing yourself — helps more.
Four 1–36 scores, one Composite
Each core section is scored 1–36, and the Composite is their average (English, Math, Reading), rounded to the nearest whole number. If you take Science, it's reported as its own 1–36 score and, with Math, forms a separate STEM score. The optional essay is scored on its own scale and doesn't affect the Composite. There's no penalty for a wrong answer, so always fill in every bubble.
How to prepare for the ACT
- Practice each section, then sit full-length tests under real timing.
- Decide early whether you'll take the optional Science section.
- Build pace — the ACT rewards speed as much as accuracy.
- Answer every question; there's no wrong-answer penalty.
