You’ll get a countdown and a daily pace — a study signal, never a pass guarantee.
Or pick the exact date
The ACT measures the English, math, reading, and scientific-reasoning skills colleges use to gauge readiness. Its English section tests grammar, usage, punctuation, and clear expression; Math covers algebra, geometry, and quantitative problem-solving; Reading rewards close, accurate reading under time pressure; and Science is really a data-reasoning section — interpreting graphs, tables, and experiments rather than recalling facts.
These are skills you build, not facts you cram. Keentune’s adaptive drills target the exact abilities each ACT section rewards, meeting you at your level and getting harder as you improve. Use the sections below to practice the skill behind each part of the test.
Your first scored practice exam is free · unlimited with Pro
Grammar, usage and punctuation, plus the editing judgement of choosing which revision actually serves the passage. The fastest section per question, at roughly 42 seconds each.
Math
50 min · 45 questions
Algebra, geometry and quantitative problem-solving, at about 67 seconds a question — the most generous per-question pacing on the test.
Reading
40 min · 36 questions
Close reading under real time pressure: detail, inference and vocabulary in context across several passages.
Science
40 min · optional · 40 questions
Interpretation, analysis and reasoning over biology, chemistry and Earth and space science — read from graphs, tables and described experiments rather than recalled. Optional, and it does not affect the Composite.
Writing
40 min · optional · 1 prompt
One essay, scored 2–12 from four domains: Ideas and Analysis, Development and Support, Organization, and Language Use and Conventions. Optional, and reported separately from the Composite.

Practice aligned to the ACT’s skill areas. The practice exam mirrors the ACT’s three core sections — English, Math and Reading, 131 questions, 2 h 5 min — and reports only a raw correct-out-of-total score by section: it never predicts a scaled 1–36 section score or Composite, and the optional Science and Writing sections are not included.

Yes. ACT states that the Science and Writing sections are both optional and that neither affects your Composite score. That is a meaningful change from how the test is still described in most older material, where Science was one of four sections feeding the Composite. Two practical consequences: your Composite now rests on three sections rather than four, so each one carries more weight, and whether to sit Science at all is a question to answer from the requirements of the colleges you are applying to rather than from habit.
How is the ACT scored?
Each section is scored 1 to 36. The Composite is the average of your English, Math and Reading scores, rounded to the nearest whole number, and it also runs 1 to 36. The optional Writing test is reported separately on a 2 to 12 scale, built as the sum of two readers’ domain scores across four domains: Ideas and Analysis, Development and Support, Organization, and Language Use and Conventions. You may also see derived STEM and ELA scores — STEM averaging Math and Science, ELA averaging English, Reading and Writing where those were taken.
How long is the ACT?
The three core sections take two hours and five minutes in total: English is 35 minutes for 50 questions, Math is 50 minutes for 45, and Reading is 40 minutes for 36. Adding the optional Science section costs another 40 minutes for 40 questions, and the optional Writing essay another 40. The pacing differs sharply by section — about 42 seconds per English question against roughly 67 for Math — so "running out of time on the ACT" usually means running out of time on English or Reading specifically.
What is on the ACT?
English tests grammar, usage and punctuation alongside the judgement of which revision genuinely improves a passage. Math covers algebra, geometry and quantitative problem-solving. Reading is close reading under time pressure — detail, inference and vocabulary in context. The optional Science section is a data-reasoning section rather than a recall one: it asks you to interpret graphs, tables and described experiments across biology, chemistry and Earth and space science, so knowing the subject matters far less than reading the figure accurately.
What is a good ACT score?
The scale runs 1 to 36 for each section and for the Composite, so the arithmetic midpoint is around 18 — but a midpoint is not a target. What counts as competitive is set by each college, differs by programme, and is revised every admissions cycle, so the only number that means anything for you is the score range a specific school publishes for its admitted students. Pick the two or three you actually care about and work backwards from what they publish.
What are the STEM and ELA scores on my ACT report?
They are derived summaries rather than separate tests, so you do not sit anything extra for them. STEM averages your Math and Science scores; ELA averages English, Reading and Writing, where those were taken. Because both depend on optional sections, they only appear when you have sat the relevant ones — a report without Science carries no STEM score. They exist to give programmes a single figure for the side of the test they care about most, which is why a technical programme may look at STEM before the Composite.
