SAT Reading & Writing

Information & Ideas

Comprehension, inference, and command of evidence — including questions where a table or graph supports a claim.

Approach

  • Base every answer strictly on the passage or the data — no outside knowledge.
  • For command-of-evidence, match the specific claim to the exact data point that proves it.
  • For inference, the answer must be directly supported, not just possible.

Common traps

  • Data misreads: the wrong row/column, a reversed trend, or an unsupported comparison.
  • 'Could be true' choices when the question needs 'must be true'.

Craft & Structure

Words in context, the purpose/structure of text, and connections across two passages.

Approach

  • For words-in-context, plug each choice back in and test the sentence's logic — ignore the word's most common meaning.
  • Ask what a sentence or paragraph is doing (introduce, contrast, illustrate), not just what it says.
  • For paired texts, pin down each author's point before comparing them.

Common traps

  • Picking a word's everyday definition instead of the meaning the context demands.
  • Confusing a text's structure/purpose with its content.

Expression of Ideas

Rhetorical synthesis (using notes to meet a goal) and choosing the most logical transition.

Approach

  • For transitions, name the relationship between the two ideas (contrast, cause, example) first, then pick the matching word.
  • For synthesis, re-read the stated GOAL and use only the given bullet notes.

Common traps

  • A transition that reads smoothly but signals the wrong logical relationship.
  • Synthesis choices that are accurate but don't accomplish the stated goal.

Standard English Conventions

Grammar, usage, and punctuation — sentence boundaries, agreement, and punctuating clauses and lists.

Approach

  • Check subject–verb and pronoun agreement, verb tense, and modifier placement.
  • Watch sentence boundaries: comma splices and run-ons are the most tested error.
  • Read the sentence with each option inserted — the correct one is grammatical, not just smooth.

Common traps

  • Choosing what 'sounds right' over what is grammatically correct.
  • A comma where a semicolon or period is required between independent clauses.
