ACT English: separate grammar rules from rhetorical decisions

First identify the question family

ACT English questions usually ask either whether a sentence follows a language rule or whether it works in the passage. Rule questions cover boundaries, punctuation, agreement, modifiers and usage. Rhetorical questions cover purpose, relevance, organisation, transitions and style.

Mixing the families causes avoidable mistakes. A grammatically correct sentence can still be irrelevant, and an excellent idea can still contain a comma splice. Name the family before comparing choices.

For rule questions, diagnose before choosing

• Look at the words on both sides of punctuation and decide whether each side is a complete sentence.
• Find the true subject before checking verb agreement.
• Place a modifier beside the word it logically describes.
• Prefer the concise choice only after confirming it preserves the full meaning.

For rhetorical questions, read around the line

A transition depends on the relationship between the surrounding ideas, not on which word sounds formal. State the relationship first—contrast, cause, example, continuation—then choose.

For add/delete and sentence-placement questions, identify the paragraph's job. Keep material that advances that job and place it where known information leads naturally to new information.

Build a rule log

Write each missed question as a reusable rule, not as the original sentence. ‘Two complete sentences need a period, semicolon or comma plus coordinating conjunction’ is reusable. ‘I chose B’ is not.
