AP United States History Study Guide
APUSH covers roughly 500 years of US history across nine chronological periods, from pre-Columbian societies through the present. The exam rewards historical reasoning skills (causation, comparison, continuity/change) as much as raw facts — memorizing dates without understanding why events connect rarely earns full FRQ credit.

Common Mistakes to Avoid
- Treating the DBQ as a document-summary exercise instead of using documents as evidence for an original argument.
- Writing a thesis that just restates the prompt instead of making a defensible, arguable claim.
- Skipping contextualization — the DBQ and LEQ both reward situating your argument in a broader historical context, not just the specific years in the prompt.
- Memorizing isolated facts instead of practicing how periods connect (causation and continuity/change over time are tested skills, not just content).
