SAT Reading and Writing Study Guide

Each question gives you a short passage — usually a paragraph or less — drawn from literature, history, social science, the humanities, or science, sometimes with a small table or graph. You answer one question about that passage, then move on to a fresh one. There is no need to hold a thousand-word article in your head.

The questions split into two broad jobs. Reading questions ask you to find a main idea, interpret a word in context, use evidence (textual or from a chart), or see how two texts relate. Writing questions ask you to edit: fix grammar and punctuation, combine sentences, or choose the transition or addition that best fits the writer's goal. Questions within a module are loosely grouped by type and roughly by difficulty, so the section has a predictable rhythm once you have seen it a few times.

The College Board organizes the questions into four content domains with roughly these shares of the section:

• Craft and Structure — ~28%
• Information and Ideas — ~26%
• Standard English Conventions — ~26%
• Expression of Ideas — ~20%

The split is remarkably even, which means no single area is safe to skip. Craft and Structure covers vocabulary in context, text structure, and purpose. Information and Ideas covers central ideas, supporting details, inference, and command of evidence — including data from graphs. Standard English Conventions is pure grammar and punctuation (sentence boundaries, verbs, pronouns, commas). Expression of Ideas is rhetorical editing: transitions and using notes to meet a stated goal. Because the four are close in weight, broad competence beats deep specialization.

Reading and Writing rewards precision, not speed-reading. A routine that works:

1. Read the question before the answer choices. Know exactly what is being asked — main idea, inference, or a grammar fix — so you read the passage with a purpose.
2. Find the answer in the text, then match. For reading questions, decide what the passage supports before looking at the options, then pick the choice that fits. The wrong answers are engineered to sound plausible.
3. Learn a short grammar checklist. A handful of rules — subject-verb agreement, pronoun clarity, sentence boundaries, and comma/semicolon/colon use — covers most Standard English Conventions points. Drill them until they are reflexive.
4. Treat transitions logically. For transition questions, name the relationship (contrast, cause, example) the passage needs, then choose the word that signals it — do not go by what "sounds smooth."
5. Review with full solutions. Understanding why the credited answer wins and why each distractor was a trap is the fastest way to stop repeating the same mistakes.

• Picking the answer that is true but unsupported by this particular passage — the test rewards what the text says, not outside knowledge.
• Falling for the choice that reuses passage words but distorts the meaning.
• Over-reading inferences — the right inference is a small, safe step from the text, not a dramatic leap.
• Choosing the longest or most formal-sounding edit when the shortest grammatically correct option is usually right.
• Judging transitions by sound instead of by the logical relationship between the sentences.
• Leaving questions blank — there is no penalty for guessing, so every question should get an answer even when you are short on time.

Every domain below has a focused practice set with full written explanations and a rationale for every wrong choice, plus a worked-solutions page you can read straight through. Start with whichever domain feels shakiest — grammar and vocabulary-in-context are the fastest to improve — then take a mixed set across the whole section to rehearse switching between reading and editing on the fly. It is free and needs no account.
