How to Practice for ACT English: Grammar Accounts for 40%, While the Other 60% Focuses on Context

Chinese students often treat the ACT English section as a "grammar test": memorize a few punctuation rules, do a few practice sets, and think they're good to go. But looking at the official ACT guidelines reveals that pure grammar and punctuation account for only about 40%, while the other 60% tests article organization, cohesion, and word choice. This is also why many students get stuck at 28 or 29 and can't break through.

Based on the official ACT English test description and the scoring table from an official online practice test, this article explains what the English section tests and how to practice the three question categories. For the role of English in the total score and the margin for error in the high-score range, see our guide on How to Score High on the ACT.

1. Basics of the English Section

• 50 questions in 35 minutes, of which 40 are scored; the rest are unscored pretest questions that cannot be identified during the exam;
• Format: Several passages, each followed by a set of multiple-choice questions. The paper test asks about underlined portions, while the online test asks about highlighted portions;
• Many questions have a "NO CHANGE" option;
• Average of 42 seconds per question.

2. The Three Question Categories and Official Proportions

The rightmost column comes from the scoring table of a new official ACT online practice test, which categorizes every scored question. As you can see, there are only 17 rule-based questions (Conventions of Standard English), while the other 23 require judgment based on the passage content. Practicing only grammar will solve at most 40% of the questions.

3. Score Conversion for the Same Practice Test

English score conversion table for this official practice test (varies slightly per test, for reference only):

From a 29 to a 33, it's only a difference of two questions. For students stuck at 28 or 29, the key to improving isn't learning more, but rather getting two or three of those five or six wrong questions right.

4. Conventions of Standard English: Aim for Zero Mistakes on Rules

The following practice methods are based on experience. These questions have clear right or wrong standards and should be the easiest to get perfect:

• Punctuation: Commas (non-restrictive elements, compound sentences, parentheticals), semicolons, colons, dashes, apostrophes (possessive vs. contraction, its / it's);
• Sentence Structure: Comma splices, sentence fragments, misplaced modifiers;
• Usage: Subject-verb agreement, pronoun reference and case, verb tense, comparatives, preposition collocations;
• Practice Method: Summarize the rules on a single page and categorize every wrong question under a specific rule. After two or three weeks, you'll find your mistakes concentrated on a few rules, which you can then tackle one by one.

5. Production of Writing: First, Figure Out What the Paragraph Is About

Common question formats for this category include: Should this sentence be added or deleted? Where is the best place to put it? Which transition word should be used? Which option best achieves the author's purpose?

• Understand the context first: The ACT recommends paying attention to the writing style of each passage and considering the role of the sentence containing the underlined portion within the whole passage. The answer depends on the meaning of the paragraph, not just whether the sentence itself is well-written;
• For "Add/Delete" questions, check two things: Is the sentence relevant to the paragraph's topic, and does it provide necessary information (based on experience);
• For transition word questions, look at the logical relationship: Is it contrast, cause and effect, progression, or example? Determine the relationship first, then look at the options (based on experience);
• Pay attention to questions without underlines: The official guidelines remind you that some questions ask about the entire passage or a specific section rather than a specific underlined part, indicated by a boxed question number or a highlighted asterisk. These questions usually require referring back to the whole passage or paragraph to answer.

6. Knowledge of Language: Concise, Precise, and Consistent Tone

• Concise: Among options with the same meaning, the shorter one without repetition is usually better; but a short option that deletes necessary information is wrong (based on experience);
• Precise: Subtle differences between synonyms, such as affect / effect or imply / infer;
• Consistent Tone: In a formal passage, a sudden colloquial expression is usually the part that needs to be changed.

7. Official Test-Taking Strategies

The ACT's official English test-taking advice can be summarized as follows:

1. Look carefully at what the underlined portion actually is and determine which writing element it tests;
2. Compare the differences between the options to ensure your chosen answer doesn't fix one error while introducing another;
3. First, think of the best way to write it in standard English; if the original is correct, choose "NO CHANGE";
4. Confirm that your answer meets the rhetorical needs of the passage;
5. Plug your chosen answer back into the sentence and read it again to ensure it flows well in context.

Tip #2 is especially useful for Chinese students: many options "look right," but comparing them one by one to see where they differ in punctuation, word choice, or structure often clarifies the testing point (based on experience).

8. A Practice Schedule (Example)

1. Week 1: Take a new official practice test and categorize your wrong answers by the three question types;
2. Weeks 2–3: Focus on Conventions of Standard English, compile a rule checklist, and categorize wrong questions rule by rule;
3. Weeks 4–5: Focus on Production of Writing and Knowledge of Language; for each wrong question, write down "what this paragraph is about and what role this sentence plays";
4. From Week 6: Do full 35-minute timed practice sets, and during review, compare the distribution of wrong answers across the three categories.

Prioritize new official questions for practice materials. The old versions before 2025 have different question counts and time limits; they can be used to practice rules, but not for timing or score estimation.

Conclusion

To improve your ACT English score, the key is to understand its structure: aim for zero mistakes on rule-based questions, rely on context for production questions, and pursue conciseness and precision for word choice questions. Practicing the three categories separately is much more effective than just doing endless practice sets.
