    SAT Boundaries (Punctuation and Sentence Structure) Worksheet

    Rules to remember

    Before drilling this skill, memorize the core rules below and keep them next to your scratch work.

    • Semicolons join two independent clauses — both sides must stand alone.
    • Colons introduce a list or an explanation, not a restart of the sentence.
    • Dashes can replace commas or colons for emphasis but must come in pairs if non-terminal.

    Practice routine

    Start untimed until you can explain the pattern. Then switch to timed sets so the skill holds up inside a full module.

    • Do 10 warmup questions and write down every mistake type.
    • Do 20 timed questions from the same skill.
    • Review missed questions without looking at the explanation first.
    • Repeat the misses 48 hours later to confirm the fix stuck.
