The APUSH exam tests content from all 9 periods, but they're not weighted equally. Periods 3–8 account for the vast majority of exam questions. The short-answer questions, DBQ, and long essay questions all require you to identify patterns and make connections across periods — not just memorize events.

✅ Key Takeaways
- Periods 3–8 carry the most exam weight — focus here but don't ignore the bookend periods entirely.
- APUSH FRQs reward connecting events across periods — always ask how a period's themes continue or change in the next period.
- The four major turning points to anchor everything: Constitution (1787), Compromise of 1877, New Deal (1933–38), and Civil Rights Acts (1964–65).
- Continuity and change is the core analytical framework — identify what changed, what stayed the same, and why.
- Always consider the perspective of multiple groups (enslaved people, women, Native Americans, immigrants) — not just political/military elites.
