  1. 01

    Retrieve

    Read only the period heading and explain its central story from memory before revealing the details.

  2. 02

    Connect

    Link the period to one earlier development and one later consequence using a course theme.

  3. 03

    Prove

    Choose two anchor examples and explain how each supports a defensible historical claim.

  4. 04

    Practise

    Answer the reasoning prompt aloud or in a short paragraph, then check whether you explained the relationship.

The full course story

Period-by-period review

Each period gives you a central story, anchor evidence, a cross-period connection, and an exam-style reasoning prompt.

01

Period 1

1491–1607

4%–6%

Diverse Indigenous societies adapted to regional environments before European exploration connected the Americas to an expanding Atlantic world.

Maize cultivationEuropean imperial motivesColumbian Exchange
Must connect

Environment shaped distinct Native societies; Atlantic contact then produced unequal demographic, economic, and ecological change.

Compare two regional Indigenous adaptations, then explain one major consequence of sustained Atlantic contact.

02

Period 2

1607–1754

6%–8%

European colonies developed distinct regional economies and political cultures while Native nations, settlers, and enslaved Africans shaped an expanding Atlantic system.

Chesapeake tobaccoNew England townsAtlantic slavery
Must connect

Regional geography and labor systems produced different colonial societies, yet trade and British institutions tied them together.

Compare labor and settlement patterns in two British colonial regions and explain why they differed.

03

Period 3

1754–1800

10%–17%

Imperial conflict generated colonial resistance, independence, and a contested effort to build a durable republican government.

The Revolution expanded republican ideals while unresolved disputes over power, rights, slavery, and federalism shaped the new nation.

10%–17%

Territorial growth, market expansion, democratization, and reform transformed the early republic while intensifying conflicts over slavery and federal power.

Market RevolutionJacksonian democracyAntebellum reform
Must connect

Economic and political participation broadened for many white men as Native removal, slavery, and gender inequality exposed the limits of democracy.

05

Period 5

1844–1877

10%–17%

Expansion reopened the slavery question, sectional conflict produced Civil War, and Reconstruction attempted to redefine freedom and citizenship.

Manifest DestinyCivil WarReconstruction Amendments
Must connect

The Union victory ended slavery and transformed constitutional citizenship, but violence and political retreat limited Reconstruction’s promise.

Explain the main causes of the Civil War and evaluate the extent of change produced by Reconstruction.

06

Period 6

1865–1898

10%–17%

Industrial capitalism, migration, urbanization, and western settlement concentrated wealth and power while generating new labor and reform movements.

Gilded Age industryNew immigrationPopulism
Must connect

Economic growth linked regions and created opportunity, but corporate power, labor conflict, racial hierarchy, and environmental change produced resistance.

Evaluate how industrialization changed work, migration, politics, and inequality after the Civil War.

Period 7

1890–1945

10%–17%

The United States became an industrial and global power, faced depression, expanded federal responsibility, and mobilized for two world wars.

Progressive reformNew DealWorld War II

Reform repeatedly enlarged government’s role, while overseas power and wartime mobilization reshaped the economy, society, and U.S. position in the world.

Activists pushed the nation toward broader equality while Cold War commitments and debates over government, culture, and social change polarized politics.

Explain how grassroots activism and federal action interacted during the civil rights era and why a conservative movement grew.

1980–Present

4%–6%

Conservative politics, globalization, technological change, demographic shifts, and the post–Cold War world reshaped debates about government and national identity.

Reagan conservatismGlobalizationDigital revolution

Market-oriented policy and global integration expanded as political polarization and debates over immigration, inequality, security, and social rights continued.

Evaluate continuity and change in the role of the federal government from 1980 to the present.

Evidence becomes argument

Six historical thinking skills

Content knowledge earns value when you can analyze sources, make connections, and support a line of reasoning.

Skill 1

Developments and Processes

Identify and explain what happened before evaluating why it matters.

Skill 2

Sourcing and Situation

Analyze point of view, purpose, historical situation, and audience—and explain their significance.

Skill 3

Claims and Evidence

Identify an argument, locate its support, and explain how evidence supports, modifies, or refutes a claim.

Skill 4

Contextualization

Situate a development inside the broader conditions and processes that made it possible or meaningful.

Skill 5

Making Connections

Use comparison, causation, and continuity/change to connect developments across place and time.

Skill 6

Argumentation

Develop a defensible claim, organize a line of reasoning, and use evidence purposefully.

Multiple Choice

Questions usually appear in stimulus sets. Identify the source, place it in context, and choose the option that best connects evidence to a historical development.

  • Read the source line before the question stem.
  • Eliminate answers outside the period or unsupported by the stimulus.
  • Choose the best historical relationship, not merely a true statement.
3 questions · 40 minutes · 20%

Short Answer

Answer every part directly. Make a specific claim, name precise evidence, and explain the relationship requested by the prompt.

  • Answer each lettered part separately.
  • Claim, evidence, explanation: one clear job per sentence.
  • Do not spend time writing an introduction or conclusion.
60 minutes · 25%

Document-Based Question

Build one defensible argument from seven documents and relevant outside evidence. Source documents for how point of view, purpose, situation, or audience strengthens the argument.

  • Group documents around the line of reasoning.
  • Use outside evidence as part of the argument.
  • Explain why sourcing information matters to the claim.
40 minutes · 15%

Long Essay

Choose the prompt you can support best. Establish a line of reasoning, contextualize, and use specific evidence to prove—not merely illustrate—the thesis.

  • Pick the option with your strongest evidence.
  • Use topic sentences as mini-claims.
  • Tie every example back to the reasoning process in the prompt.

Ready for deliberate practice

Your next review should be specific

  • Name the two periods where your central story is least clear.
  • Choose one recurring theme and trace it through at least four periods.
  • Build one comparison, one causation, and one continuity/change thesis.
  • Practise explaining why evidence supports a claim instead of listing facts.
  • Use released College Board materials or teacher-assigned AP Classroom practice for official-style questions.
