What you'll learn
Information & Ideas tests comprehension and reasoning: identifying central ideas, using textual and quantitative evidence (command of evidence), and drawing inferences. Each Digital SAT question has a short passage and one question — so close reading is everything.
Central ideas and details
The central idea is the main point the passage makes — not just the topic. Ask: what is the author mainly saying? Distractor answers are often true details that miss the overall point.
Command of evidence (textual)
These ask which choice best supports or illustrates a claim. The right answer is directly tied to the claim — not merely related to the topic. A specific fact or statistic usually beats a vague statement.
Command of evidence (quantitative)
Some questions include a graph or table. Read the axes and units, find the data point the claim depends on, and pick the choice the data actually supports. Beware choices that overstate or reverse the trend.
Inferences
An inference is a logical conclusion the text implies but doesn't state. The best answer stays close to the text — if a choice requires outside assumptions, it's probably wrong. Watch signal words like although, yet, and but that flag contrast.
Strategy
- Read the question first so you know what to look for.
- Read the passage closely — every word counts in a short text.
- Predict an answer before reading the choices.
- Eliminate choices that are too extreme, off-topic, or only half-right.
Common mistakes
- Choosing a true detail that isn't the main idea.
- Picking an answer that's topically related but doesn't support the specific claim.
- Over-inferring beyond what the text allows.
The best-supported answer is always the safest. Practise spotting the link between claim and evidence — it's the heart of this domain.
