ACT English Mastery Guide (2026)

Section Overview

The ACT English section is the first section of the ACT. You have 45 minutes to answer 75 questions across 5 passages (15 questions per passage). That is exactly 36 seconds per question — making it one of the most time-pressured sections on any standardized test.

Each passage is a prose essay (not fiction) of approximately 350–450 words. Underlined portions of the text are numbered and correspond to a question. Some questions ask about a longer section of the passage (whole paragraph or the essay as a whole) — these are not tied to an underlined word but to a numbered placeholder at that location.

Usage/Mechanics vs Rhetorical Skills

ACT English questions fall into two broad categories with distinct sub-skills:

Usage/Mechanics questions are rule-based — you either know the grammar rule or you do not. Rhetorical Skills questions require you to evaluate the passage's purpose, logic, and style — they take more reading and judgment.

Punctuation Rules

Punctuation questions (~13% of the test) test commas, apostrophes, colons, semicolons, periods, and dashes. The same rules that apply on the SAT apply here — the ACT is slightly less formula-driven and more contextual.

Key comma rules

• Between two independent clauses with a conjunction: She studied, and she passed.
• After an introductory clause/phrase: After weeks of practice, she performed flawlessly.
• Around non-essential information: The report, which took months to complete, was well received.
• Between items in a list: The test covers grammar, punctuation, and rhetoric. (Oxford comma used)
• Never between subject and verb: The researcher, published her findings. ✗

Colons and semicolons

Semicolons join two independent clauses. Colons introduce a list or explanation after an independent clause. Same rules as the SAT — the ACT tests these with the same logic.

Grammar & Usage

Grammar & Usage questions (~16% of the test) test agreement, pronoun use, verb forms, and modifier placement. Key topics:

• Subject-verb agreement: Cross out intervening phrases to find the true subject-verb pair. Collective nouns (team, committee, jury) take singular verbs.
• Pronoun-antecedent agreement: The pronoun must match its antecedent in number. Watch for "each," "every," "none" — all singular.
• Pronoun case: Subject pronouns (I, he, she, they) vs. object pronouns (me, him, her, them). Use subject pronouns as subjects; object pronouns as objects.
• Verb tense consistency: Match tense to the context of the surrounding passage. Look for tense signals ("in 1850," "currently," "will").
• Misplaced modifiers: The modifier must be placed immediately next to what it modifies. "Running through the forest, the trees were dense." ✗ (trees are not running)
• Idioms: Preposition usage — "interested in," not "interested at." "Different from," not "different than."

Sentence Structure

Sentence Structure questions (~24% of the test) test the largest sub-category in Usage/Mechanics. Topics include:

• Comma splices and run-ons: Two independent clauses must be properly joined (semicolon, period, or comma + FANBOYS)
• Sentence fragments: A group of words that lacks a subject, verb, or complete thought. "Although the study was long." is a fragment.
• Parallel structure: Items in a list must share the same grammatical form — all nouns, all infinitives, or all gerunds. "She enjoys hiking, to swim, and running." ✗
• Dangling and misplaced modifiers: The introductory phrase must logically modify the subject of the main clause.
• Transition words in context: The ACT tests whether a transition word (however, therefore, in addition) correctly reflects the logical relationship between sentences.

Strategy & Organization

Strategy questions (~16% of the test) ask whether a sentence or detail should be added, deleted, or changed to best serve the essay's purpose. The question gives you the writer's goal and asks you to evaluate whether a choice accomplishes it.

Organization questions (~15% of the test) test the logical order of sentences within a paragraph or paragraphs within the essay, and the appropriateness of introductory and concluding sentences.

Tips for Strategy questions

• Read the stated goal in the question carefully — only accept an answer that specifically accomplishes that goal
• When asked whether to add a detail, decide if it is relevant to the main point of that paragraph — if it introduces a new, unrelated idea, omit it
• When asked whether to delete an underlined portion, ask: does removing it change the meaning or lose important information? If "No," you can usually delete it

Style

Style questions (~16% of the test) ask which choice produces the clearest, most precise, and most appropriate writing. Three key style principles the ACT tests:

• Conciseness: Remove redundant words. "He is a person who studies biology" → "He studies biology." The shorter, clearer option is almost always correct.
• Avoiding wordiness: Do not repeat ideas already stated. If one word conveys the meaning, do not use three.
• Appropriate tone: Match the formality of the surrounding essay. Casual slang in an academic essay is wrong; overly formal language in a personal narrative is wrong.

The OMIT Strategy

One of the four answer choices for many ACT English questions is "OMIT the underlined portion" (or "DELETE the underlined portion"). This choice removes the underlined text entirely.

The rule: If the underlined portion is redundant, introduces information already stated nearby, adds detail that is irrelevant to the main point, or makes the sentence wordy without adding meaning — choose OMIT. The ACT rewards concise writing.

On Style and Strategy questions, OMIT is correct roughly 20–30% of the time. Do not avoid it — but also do not reflexively choose it. Always confirm that removing the underlined text leaves a grammatically complete, logically coherent sentence.

Transitions: FANBOYS & Subordinating Conjunctions

Coordinating conjunctions (FANBOYS)

FANBOYS: For, And, Nor, But, Or, Yet, So

These join two independent clauses and require a comma before them. They each signal a different relationship: "and" (addition), "but/yet" (contrast), "so" (result), "for" (reason), "or" (alternative), "nor" (negative alternative).

Subordinating conjunctions

These create a dependent clause: because, although, while, since, when, before, after, if, unless, as, even though, rather than, whereas, until. A sentence that starts with a subordinating conjunction is incomplete by itself — it must attach to an independent clause.

Conjunctive adverbs (transition words)

However, therefore, consequently, moreover, furthermore, in addition, nevertheless, thus, accordingly — these are NOT conjunctions. They do not join two independent clauses by themselves. You still need a semicolon or period between ICs when using them.

Matching transitions to relationships

Apostrophes

Apostrophes on the ACT serve two purposes: possessive and contraction. A common wrong answer type adds an apostrophe to a plural (which never gets an apostrophe unless it is also possessive).

Common Question Stems

Recognizing the question stem tells you immediately what skill is being tested, saving time.

"Which Answer Is NOT Acceptable?"

This question type is unique to the ACT and trips up many students. The question gives you the original underlined text and asks which of the four answer choices CANNOT replace it — meaning the wrong answer is the one that is unacceptable.

Strategy: Identify what grammatical or rhetorical feature the underlined portion requires. Then test each answer choice: does it preserve that feature? Three choices will; one will create an error or logical inconsistency. That one is the answer.

Common mistakes on "NOT acceptable" questions: students choose an option that sounds slightly different or less elegant — but is still grammatically correct. Only eliminate options that create an actual grammar error, logical contradiction, or tonal problem.

Time Strategy

At 36 seconds per question, the ACT English section is a race. Here is how to manage it:

• Target 9 minutes per passage. After each passage, note your time. If you are running over, speed up on Rhetorical Skills questions (they tend to be faster than Grammar questions for most students).
• Read the passage before answering questions. Unlike the SAT, ACT English passages have questions tied to specific underlined portions — so you need to read a few sentences of context, not the whole passage first.
• For Grammar questions: read the whole sentence containing the underlined portion, plus the sentences immediately before and after. Most grammar errors are visible in a single sentence.
• For Rhetorical Skills questions: read more context. Strategy and Organization questions often require understanding a full paragraph or the essay's overall purpose.
• Never leave a question blank. There is no penalty for wrong answers — guess if you are out of time.
