What this domain covers

Words in context (vocabulary from usage)
Text structure and purpose
Cross-text connections (two short passages)
Author tone and rhetorical function

Strategy that actually works

1For vocabulary questions, cover the answer choices and predict the word yourself first.
2Cross-text questions: identify each author's stance in one phrase before comparing.
3Function questions ("the underlined sentence serves to…") — look for the sentence's relationship to the one before it.
4Watch for shifts in tone signaled by however, yet, although.

Frequently asked

How do I study vocabulary for the Digital SAT?+

Do not memorize word lists. Instead, practice inferring word meaning from context on 200+ real questions — that is the exact skill the SAT tests.

What are cross-text questions?+

You get two short passages on related topics and answer a question about their relationship. The key is identifying each author's claim precisely.

Is Craft and Structure harder than Information and Ideas?+

Most students find Craft and Structure harder because it demands both vocabulary and structural reasoning. It is also the largest R&W domain, so time spent here pays off most.
