The ACT with Writing takes about 2 hours 45 minutes of testing time for the core sections plus Science (if taken) plus the 40-minute essay, and total seated time—including check-in, instructions, and breaks—often runs 3.5 to 4+ hours. Plan for a long morning. Part of how long is the ACT.
Testing time breakdown
- Core only (no Science, no Writing): ~2 hours 5 minutes
- Core + Science: ~2 hours 45 minutes
- Core + Writing: ~2 hours 45 minutes
- Core + Science + Writing: ~3 hours 25 minutes
Writing always comes last, after English, Math, Reading, and Science (if you chose it).
Total seated time is longer
Add check-in, ID verification, seating, section instructions, and short breaks between sections. Many students should plan to be at the center early and expect a long morning even when the section timers look shorter than older ACT guides suggest. Stamina tips in building ACT test-taking stamina.
When to skip Writing to shorten the day
If none of your colleges require or recommend the essay, skipping Writing removes 40 minutes of testing plus fatigue before you would have started the essay. Decision guide: should you take the ACT Writing section; which schools to verify: which colleges require ACT Writing.
Pair with your other optional choices
Science and Writing are both optional on the enhanced ACT. Decide them together based on your college list. See is ACT Science optional and enhanced ACT changes explained.
