What SAT grammar rules should I study first?

Short answer

Review sentence boundaries, punctuation, subject-verb agreement, pronouns, modifiers, and parallel structure first. These rules appear often and are easy to review by pattern.

What to do next

Sort missed grammar questions into rule families instead of writing a generic note like grammar mistake.

Common mistake

Students memorize rare grammar terms while missing the same comma splice or modifier pattern repeatedly.

How to run the drill

  1. Copy the sentence with the answer blanked out, then mark the subject, verb, and punctuation around the blank.
  2. Name the rule family before looking at the correct answer: boundary, punctuation, agreement, pronoun, modifier, or parallel structure.
  3. Write why the wrong answer looked tempting in one short phrase.
  4. Redo one more question from the same rule family before moving to a new grammar topic.

A better grammar note

Write "missed sentence boundary after a complete thought" instead of "grammar." The next rep should test the same boundary move with different wording.

How to review it

Treat this as a pattern, not a one-off fact. Name the task, write the mistake in plain language, and connect it to the next drill or guide. For the deeper explanation, open the related Askiras guide below.
