The enhanced ACT core is 131 multiple-choice questions: 50 English, 45 Math, and 36 Reading. Optional Science adds 40. Optional Writing is one essay. The Composite averages only the three core sections.
The core
- English: 50 questions, 35 minutes.
- Math: 45 questions, 50 minutes, four choices (A–D).
- Reading: 36 questions, 40 minutes, four single passages.
Time per item: time per question. Total length: how long is the ACT.
Optional add-ons
Science is 40 questions in 40 minutes and does not enter the Composite. Writing is a separate 2–12 score. Is Science optional, should you take Writing.
The bottom line
Memorize 50 / 45 / 36 for the score that colleges average. Add 40 Science or an essay only if a campus will read them.
