If the last thing you heard about the ACT was "215 questions, four sections, three hours," that information is out of date. Starting with digital administrations in April 2025 and reaching every national, state, and school-day test by spring 2026, the ACT moved to what ACT, Inc. calls the Enhanced ACT — and the old "classic" version is retired. There's no longer a choice between formats: whatever date you sit for, you're taking the Enhanced ACT.
The core test now covers three required sections — English, Math, and Reading — totaling 131 questions in about 2 hours and 5 minutes. Science is optional and no longer factors into your 1–36 Composite score; if you take it, it's reported as a separate Science score (and, combined with Math, as a STEM score). Writing remains a separate optional essay, scored 2–12, that also sits outside the Composite.
The practical effect for pacing: you get roughly 18% more time per question than the old format allowed. That sounds like relief, and it partly is — but ACT, Inc. has been clear that content difficulty wasn't reduced to compensate. Fewer questions means each one carries more weight, and a careless slip costs you more of your score than it used to.
Section | Questions | Time | Share of Core Test | Counts Toward Composite? |
|---|---|---|---|---|
English | 50 | 35 min | 38.2% | Yes |
Math | 45 | 50 min | 34.4% | Yes |
Reading | 36 | 40 min | 27.5% | Yes |
Science (optional) | 40 | 35 min | — (separate score) | No — reported separately |
Writing (optional) | 1 essay | 40 min | — (separate score) | No — scored 2–12 |
Add Science and you're looking at about 2 hours 40 minutes total; add Writing on top of that and it's closer to 3 hours 20 minutes. Science costs an extra $4 at registration and Writing an extra $25, on top of the $68 base fee for English, Math, and Reading — figures as published on for testing through July 2026.
Whether to sit for Science at all. This is the decision unique to this exam cycle, and a lot of students get it wrong in both directions. Skipping Science shortens your test day and removes a section some students find their weakest. But a growing number of colleges still expect or prefer a Science score for STEM-track applicants, and "no Science score" can read as a gap on an application rather than a neutral omission. Check your target schools' current policy before deciding — this is genuinely still shaking out school by school in 2026, and blanket advice either way isn't reliable yet.
The new four-answer-choice Math format. Legacy ACT Math questions offered five answer choices; the Enhanced version trimmed that to four, matching English and Reading. It sounds trivial, but it changes elimination strategy — you have less room to rule out obviously wrong answers before guessing, which raises the value of actually solving rather than narrowing.
Reading passage count versus question density. The section kept its four passage types (literary narrative, social science, humanities, natural science) but dropped from 40 questions to 36. Passages themselves got shorter too, so the skill being tested shifted slightly — less endurance-reading, more efficient extraction of the specific detail a question is actually asking about.
Grammar rules that show up disproportionately. Comma usage in complex sentences, subject-verb agreement across long noun phrases, and rhetorical "add/delete this sentence" questions remain the highest-miss categories in English, format change or not — the content pool for grammar mechanics hasn't shifted just because the section got shorter.
The single most common prep mistake right now is practicing on legacy-format material without adjusting it. If you're working from an older ACT book or PDF, the question counts and timing on the page won't match test day. Either use materials built for the Enhanced format specifically, or adapt older ones: for English, work only the first 50 questions under a 35-minute clock; for Math, the first 45 questions under 50 minutes; for Reading, all four passages but capped at 36 questions in 40 minutes.
Beyond that adjustment, the ACT rewards a specific kind of practice discipline: full sections, timed, with review that focuses on why a wrong answer was tempting — not just which answer was correct. English and Math questions are largely rule-based and recall-driven, so repetition against your own error patterns closes gaps quickly. Reading and Science are closer to skills than facts, which means volume matters less than deliberately practicing the specific move you're weak on — say, locating evidence for inference questions, or reading a data table before touching the answer choices.
Studying from unadjusted legacy-format practice tests and walking in surprised by the pacing
Treating the Science decision as an afterthought instead of checking target-college policy in advance
Over-preparing English grammar rules while neglecting rhetorical/organization questions, which now make up a larger share of a shorter section
Skipping full-length timed run-throughs and only doing untimed section drills, which hides pacing problems until test day
Not reviewing wrong answers closely enough to catch a repeating error pattern (careless elimination, second-guessing correct instincts, running out of time on the same question type every time)
Starting from scratch, no recent standardized test practice: Plan on 8–10 weeks. Spend the first two to three weeks on a diagnostic and English/Math fundamentals, the next few weeks layering in Reading and Science strategy, and the final two weeks on full-length, timed practice tests under Enhanced-format timing.
Coming in with strong grades or recent SAT/PSAT experience: 4–6 weeks is usually enough. Skip straight to a diagnostic, isolate your two or three weakest question types, and spend most of your remaining time on timed full sections rather than content review you've already got.
Retaking after a first attempt: Go straight to your previous score report. The ACT breaks down performance by content category, so a retake plan should target those specific categories rather than repeating a generic full study plan — most retake gains come from fixing two or three identifiable weak spots, not from re-learning everything.
This is worth calling out because it directly affects which prep materials are still valid. The rollout happened in stages: digital national testing moved to the Enhanced format in April 2025, national paper and digital testing followed in September 2025, and school-day and state-contracted administrations (the version many juniors take through their high school) shifted starting spring 2026. As of spring 2026, every ACT administration — national Saturday testing, school-day, and state/district — uses the Enhanced format; the legacy 215-question version is fully retired. If you're using inherited study materials — an older sibling's prep book, a hand-me-down practice test — confirm it reflects the Enhanced format before relying on its timing or question counts.
