SAT Punctuation Rules Chart

Core punctuation rules

The SAT rewards function, not vibes. Identify what each punctuation mark is doing in the sentence.

Fast check

If punctuation joins clauses, label each side as independent or dependent before choosing.

How to use this on 1600.now

Read the chart once, then switch into practice. The site is built around filtered bank questions, timed modules, score tools, and saved practice sets, so the next step should be an action inside one of those tools.

• Use the question bank when the page names a skill or domain.
• Use timed modules when the page is about pacing or test format.
• Use score tools when the page is about score targets or admissions decisions.

How to turn this into Reading and Writing points

For Reading and Writing resources, most improvement comes from slowing down the decision step. Name the question type, predict the job of the answer, then compare choices.

• For grammar, identify the tested rule before reading all four choices.
• For evidence and inference, prove the answer from a specific phrase in the passage.
• For transitions, decide the logical relationship before looking at choices.
• For vocabulary, replace the word in context and reject choices with the wrong tone or direction.
