ACT English: The 15 Grammar Rules Tested Every Time
The ACT English section tests the same grammar rules repeatedly. Mastering these 15 rules virtually guarantees improvement.
Punctuation Rules
Commas with independent clauses, semicolons between sentences, colons before lists or explanations, and apostrophe usage account for roughly 20% of questions.
Sentence Structure
Subject-verb agreement, pronoun-antecedent agreement, parallel structure, and modifier placement are tested heavily. These are predictable and learnable.
Rhetorical Skills
Transition words, sentence placement, conciseness, and tone consistency. These questions test whether writing is effective, not just grammatically correct.
