College Board divides Reading and Writing into four tested domains. Understanding each one helps you target your preparation efficiently.
Craft & Structure (~28%)
These questions test your ability to determine the meaning of words and phrases in context, understand text structure, and analyze how an author’s choices shape meaning and tone. Vocabulary-in-context and purpose questions are the most common types in this domain.
Information & Ideas (~26%)
This domain focuses on reading comprehension: identifying central ideas, supporting details, and drawing inferences. You will also encounter questions about how quantitative data (tables, graphs) relate to a passage’s claims, as well as questions comparing two short texts on the same topic.
Standard English Conventions (~26%)
Grammar and mechanics questions covering sentence boundaries, subject-verb agreement, pronoun-antecedent agreement, verb tense and form, punctuation (especially commas, semicolons, and apostrophes), and parallel structure. These questions are often the fastest to answer once you know the rules.
Expression of Ideas (~20%)
Questions about rhetorical effectiveness: choosing the best transition, combining or reordering sentences for clarity, and selecting language that matches a passage’s purpose and audience. Synthesis questions that ask you to incorporate notes or bullet points into a coherent sentence also appear here.
