Units and exam weighting

Period 1: 1491–1607 4–6% of the exam

Native American societies before European contact, European exploration, the Columbian Exchange, Spanish colonisation and its labour systems.

3 of 15 questions in this unit, with the worked answer

Which factor best explains the wide diversity among Native American societies in the Americas before 1491?

Answer. Adaptation to distinct regional environments and resources

Native societies developed different economies, settlement patterns, and social structures based on local geography, climate, and available resources, from Pueblo irrigation farming to Pacific Northwest fishing economies.

What Native American culture, centered near present-day St. Louis, built large earthen mounds and supported a complex hierarchical society through maize agriculture and trade?

Answer. Mississippian culture (Cahokia)

Cahokia was the largest Mississippian settlement, evidence of social stratification, organized labor for mound construction, and extensive trade networks reaching across much of North America.

Name two technological innovations that enabled European transoceanic exploration in the 15th century.

Answer. The caravel (a maneuverable sailing ship) and the magnetic compass (or astrolabe for navigation)

These innovations allowed ships to sail against the wind more effectively and to determine position at sea, making long ocean voyages feasible for the first time.

What people get wrong

  1. Treating pre-Columbian Native societies as one uniform culture. Instead, always specify a region (Southwest, Plains, Pacific Northwest, Eastern Woodlands) and its distinct environmental adaptation.
  2. Equating the encomienda system with chattel slavery. Instead, note encomienda nominally required 'protection' and conversion and did not (in law) involve ownership of a person, even though abuses made conditions brutal.
  3. Assuming European disease spread was a deliberate strategy in this period. Instead, describe it as largely unintentional early on, though it still devastated Native populations and enabled conquest.
  4. Describing the Columbian Exchange as purely negative. Instead, address both sides: catastrophic for Native American demographics, but a major driver of population growth and dietary change in Europe.

Period 2: 1607–1754 6–8% of the exam

European colonisation of North America, regional differences among the colonies, transatlantic trade and slavery, colonial society and the Great Awakening.

3 of 12 questions in this unit, with the worked answer

Which economic theory held that colonies existed primarily to enrich the mother country by supplying raw materials and consuming its manufactured goods?

Answer. Mercantilism

Mercantilism tied colonial existence directly to the economic benefit of the mother country, which is why England enforced the Navigation Acts to keep colonial trade flowing through English hands.

What was the primary purpose of the headright system in colonial Virginia?

Answer. To encourage immigration and the importation of laborers by granting land for each person brought to the colony

Because tobacco cultivation demanded large tracts of land and abundant labor, Virginia offered land grants per settler or servant transported, directly fueling the growth of large plantations.

Explain why the labor system in the Chesapeake colonies shifted from indentured servitude to chattel slavery in the late seventeenth century.

Answer. Falling supply of English servants, rising tobacco profits, and fear of freed servants (crystallized by Bacon's Rebellion in 1676) pushed planters toward a cheaper, permanent, and more controllable labor source in enslaved Africans

Bacon's Rebellion showed planters the danger of a growing class of poor, landless former servants; shifting to lifelong, hereditary enslaved labor removed that political threat while also locking in a permanent workforce as servant immigration declined.

What people get wrong

  1. Treating indentured servitude and chattel slavery as interchangeable. Instead, note that indentured servitude was temporary and not racially hereditary, while chattel slavery was lifelong and passed to children — the shift between them after events like Bacon's Rebellion (1676) is itself a testable cause-and-effect.
  2. Assuming every English colony was founded for religious freedom. Instead, sort founding motives by colony: Massachusetts and Pennsylvania were religious projects, but Virginia, Carolina, and Georgia were founded chiefly for profit or strategic buffer purposes.
  3. Confusing mercantilism with free-market capitalism. Instead, remember mercantilism is a regulated, government-directed system designed to benefit the mother country, which is exactly why the Navigation Acts existed.
  4. Writing generic answers about 'the colonies' as a single unit on comparison questions. Instead, always name a specific region (New England, Middle, Chesapeake/Southern) and a specific piece of evidence, since graders reward concrete regional distinctions.

Period 3: 1754–1800 10–17% of the exam

The Seven Years' War, the road to revolution, the American Revolution, the Articles of Confederation, the Constitution, the early republic.

3 of 14 questions in this unit, with the worked answer

What was the primary purpose of the Albany Congress of 1754?

Answer. To coordinate colonial defense against the French and secure Iroquois alliance; Franklin's Albany Plan proposed intercolonial union, though colonies rejected it.

Delegates from several colonies met to plan joint action against France and to negotiate with the Iroquois Confederacy. Franklin's plan for a unified colonial government was ahead of its time and was rejected by colonial assemblies, but it foreshadowed later calls for union.

Explain why many colonists objected to the Stamp Act of 1765 on constitutional grounds rather than simply financial ones.

Answer. They argued only their own elected colonial assemblies could tax them directly, rejecting Britain's claim of 'virtual representation' in Parliament.

The Stamp Act Congress articulated 'no taxation without representation' as a constitutional principle, not just a complaint about cost. This distinguished internal taxes (like the stamp tax) from external trade regulation, which some colonists had tolerated.

The Boston Tea Party (1773) was a direct response to which act of Parliament?

Answer. The Tea Act

The Tea Act (1773) gave the British East India Company a monopoly on tea sales in the colonies, undercutting colonial merchants and smugglers; colonists dumped the tea into Boston Harbor in protest, leading Britain to pass the punitive Coercive Acts.

All 14 questions for Period 3, with the working →

What people get wrong

  1. Treating 'Federalists' (supporters of ratifying the Constitution in 1787–88) and the later 'Federalist Party' (Hamilton's political party in the 1790s) as identical. Instead, note they overlap in membership and philosophy but are chronologically and organizationally distinct.
  2. Assuming the Declaration of Independence and the Constitution express the same theory of government. Instead, recognize the Declaration emphasizes natural rights and the right to revolt, while the Constitution prioritizes stability and order, partly as a reaction to unrest like Shays' Rebellion.
  3. Describing the Articles of Confederation as a total failure with no achievements. Instead, credit real successes such as the Northwest Ordinance of 1787, which established an orderly process for admitting new states and banned slavery in the territory.
  4. Writing 'the colonists' as a unified group who all wanted independence. Instead, remember roughly a third were Patriots, a third Loyalists, and a third neutral or undecided, and say so explicitly when relevant.

Period 4: 1800–1848 10–17% of the exam

Jeffersonian and Jacksonian politics, the market revolution, expansion of democracy, reform movements, the Second Great Awakening, sectional tensions.

3 of 14 questions in this unit, with the worked answer

Jefferson opposed a national bank on strict-constructionist grounds, yet as president he took what major action that required a loose interpretation of the Constitution?

Answer. The Louisiana Purchase (1803)

The Constitution does not explicitly authorize the president to acquire foreign territory, but Jefferson set aside his usual strict construction to complete the purchase, doubling the nation's size and showing the gap between his political philosophy and his actions in office.

In Marbury v. Madison (1803), what power did the Supreme Court establish for itself?

Answer. Judicial review — the power to declare acts of Congress unconstitutional

Chief Justice John Marshall ruled that while Marbury was entitled to his commission, the section of the Judiciary Act of 1789 giving the Court original jurisdiction to issue it was unconstitutional, establishing that the Court could void federal laws conflicting with the Constitution.

What did McCulloch v. Maryland (1819) establish about the relationship between federal and state power?

Answer. Congress has implied powers to create institutions like a national bank, and states cannot tax federal instrumentalities

The Court read the Necessary and Proper Clause broadly, affirming federal supremacy over conflicting state action, a key precedent for expanding federal authority.

All 14 questions for Period 4, with the working →

What people get wrong

  1. Assuming Jefferson governed as a strict constructionist throughout his presidency — the Louisiana Purchase (1803) actually required him to set aside strict construction and use loose interpretation of the Constitution; note the contradiction explicitly rather than picking one label.
  2. Treating 'Jacksonian Democracy' as meaning democracy expanded for everyone — suffrage expansion was for white men only, while Jackson's era saw the forced removal of Native Americans and no gains (and some rollbacks) for free Black Americans and women.
  3. Confusing the Nullification Crisis with secession — South Carolina nullified a tariff, not the Union itself, and backed down after federal pressure and a compromise; save 'secession' for 1860–61.
  4. Treating the Second Great Awakening as a purely religious event disconnected from politics and reform — link it explicitly to temperance, abolition, and education reform on any FRQ, since the exam rewards causal connections across themes.

Period 5: 1844–1877 10–17% of the exam

Manifest Destiny and the Mexican-American War, the sectional crisis, the Civil War, Reconstruction and its failures.

3 of 14 questions in this unit, with the worked answer

What was the primary significance of the Wilmot Proviso (1846)?

Answer. It proposed banning slavery in any territory acquired from Mexico, and though it never passed the Senate, it revealed a growing sectional split within both major parties.

The Proviso failed as law but is significant because it showed slavery's expansion, not just its existence, was becoming the era's central political question, splitting Democrats and Whigs along regional rather than party lines.

Which provision of the Compromise of 1850 most angered Northern abolitionists?

Answer. The strengthened Fugitive Slave Act, which required Northern officials and citizens to assist in capturing escaped enslaved people and denied accused fugitives a jury trial.

While California's admission as a free state pleased the North, the Fugitive Slave Act's enforcement provisions felt like federal coercion into slavery's machinery, fueling personal liberty laws and abolitionist resistance.

Explain how popular sovereignty operated differently in practice under the Compromise of 1850 versus the Kansas-Nebraska Act of 1854.

Answer. In 1850 popular sovereignty applied to territory won from Mexico where slavery's presence was already contested but distant from settled slave states; in 1854 it applied to Kansas and Nebraska, land north of the Missouri Compromise line where slavery had been legally banned for over three decades, so its use there directly repealed existing law and triggered organized migration and violence rather than distant legislative debate.

The key difference is that the 1854 act didn't just permit a vote — it actively overturned a settled sectional boundary, converting an abstract principle into an immediate, physical contest for control of a specific territory.

All 14 questions for Period 5, with the working →

What people get wrong

  1. Treating the Wilmot Proviso as if it became law — it repeatedly passed the House but never the Senate; describe it as a failed proposal that revealed sectional divides, not as an enacted policy.
  2. Assuming the Emancipation Proclamation freed all enslaved people immediately — it applied only to areas in rebellion not under Union control as of January 1, 1863, exempting the border states and Union-occupied Confederate territory; its main effects were diplomatic (deterring British/French recognition of the Confederacy) and military (authorizing Black enlistment).
  3. Reducing the causes of the Civil War to 'states' rights' in the abstract — Confederate secession documents themselves cite the protection of slavery explicitly; always name slavery as the substantive issue states' rights arguments were deployed to protect.
  4. Confusing Lincoln's Ten Percent Plan with the Radical Republicans' Wade-Davis Bill — Lincoln's plan required only 10% of a state's 1860 voters to take a loyalty oath, while Wade-Davis demanded a majority and an 'ironclad oath'; know which plan a given document or policy reflects.

Period 6: 1865–1898 10–17% of the exam

The Gilded Age: industrialisation, the West, immigration and urbanisation, labour, populism, the politics of the era.

3 of 14 questions in this unit, with the worked answer

Which of the following best explains the primary business strategy Andrew Carnegie used to dominate the steel industry?

Answer. Vertical integration, controlling every stage of steel production from raw materials to finished product

Carnegie's company owned mines, ore transport, mills, and distribution, cutting costs by controlling every stage of steel production rather than merging with rival firms (which was Rockefeller's horizontal strategy).

Explain how the Dawes Act of 1887 changed federal policy toward Native Americans.

Answer. It shifted policy from treating tribes as sovereign nations holding land communally toward forced assimilation through individual land allotments.

The Dawes Act broke up reservations into individual family plots meant to encourage farming and Americanization, undermined tribal governance and communal landholding, and freed 'surplus' land for sale to white settlers, resulting in massive loss of Native-controlled land.

Which of the following groups most directly benefited from urban political machines like Tammany Hall in the Gilded Age?

Answer. Immigrant voters, who received jobs and services in exchange for votes

Political machines built loyalty among new immigrants by providing housing help, jobs, and social services, exchanging these favors for votes that kept the machine in power.

All 14 questions for Period 6, with the working →

What people get wrong

  1. Confusing Populism with Progressivism because both criticize big business—remember Populism is a rural, agrarian movement of the 1890s centered on currency and railroad grievances, while Progressivism is a broader, largely urban middle-class reform movement of the early 1900s.
  2. Assuming labor unions generally won their major confrontations—in fact most headline strikes of this period (Great Railroad Strike, Haymarket, Homestead, Pullman) ended in defeat for workers when state militias or federal troops backed employers; don't overstate labor's power before 1900.
  3. Treating all immigrants and all nativist responses as identical—distinguish 'new immigrants' from southern/eastern Europe and Asia, who faced sharper hostility and formal restriction (Chinese Exclusion Act, 1882), from earlier 'old immigrants' from northern/western Europe.
  4. Describing Gilded Age national politics as simply inactive or corrupt without evidence—cite specific mechanisms like patronage/spoils, the Pendleton Act's limited civil service reform, and tariff debates rather than making a vague claim about 'do-nothing' government.

Period 7: 1890–1945 10–17% of the exam

Imperialism, Progressivism, World War I, the 1920s, the Great Depression and the New Deal, World War II.

3 of 15 questions in this unit, with the worked answer

Which factor most directly justified American overseas expansion in the 1890s, according to imperialists like Alfred Thayer Mahan?

Answer. The need for a strong navy, overseas coaling stations, and new markets for surplus industrial goods

Mahan's 'The Influence of Sea Power upon History' argued that national greatness required a powerful navy and overseas bases, which fed directly into the push for Hawaii, the Philippines, and Caribbean influence. This is a classic causation link between economic and strategic motives and imperial policy.

How did the Spanish-American War of 1898 mark a turning point in U.S. foreign policy?

Answer. It transformed the U.S. from a continental power into an overseas colonial power by giving it control of the Philippines, Puerto Rico, and Guam, and a protectorate over Cuba.

Victory over Spain brought territorial acquisitions outside North America for the first time, forcing debates (the 'Anti-Imperialist League' vs. expansionists) over whether the U.S. should govern colonies, a sharp break from prior policy focused on continental expansion.

What did the Platt Amendment (1901) require of Cuba?

Answer. Cuba had to allow U.S. naval bases (including Guantánamo Bay), limit its ability to make treaties with other nations, and permit U.S. intervention to preserve order.

The Platt Amendment made Cuba a de facto U.S. protectorate even after nominal independence, illustrating how imperial control could take indirect forms besides outright annexation.

All 15 questions for Period 7, with the working →

What people get wrong

  1. Treating 'imperialism' and 'Progressivism' as unrelated topics — in fact many Progressives (like Theodore Roosevelt) supported imperialism, so don't assume all reform-minded figures opposed overseas expansion.
  2. Assuming the U.S. entered WWI immediately after the Lusitania sank in 1915 — it did not; the U.S. stayed neutral for nearly two more years until unrestricted submarine warfare resumed and the Zimmermann Telegram was revealed in 1917. Keep the timeline precise.
  3. Confusing the First New Deal (1933–34, relief and recovery, e.g. NIRA, AAA) with the Second New Deal (1935–38, reform and worker protections, e.g. Wagner Act, Social Security) — the exam often tests which specific programs belong to which phase.
  4. Writing that the New Deal 'ended the Great Depression' — most historians and the AP framework treat WWII wartime spending and mobilization as what actually restored full employment, while the New Deal provided relief and reform but not full recovery.

Period 8: 1945–1980 10–17% of the exam

The Cold War, postwar prosperity, the civil rights movement, the Great Society, Vietnam, the 1970s.

3 of 14 questions in this unit, with the worked answer

What policy did George Kennan's 1946 'Long Telegram' help establish as the foundation of US Cold War strategy?

Answer. Containment

Kennan argued the Soviet Union's expansionist tendencies had to be met with 'long-term, patient but firm and vigilant containment,' shaping US foreign policy from the Truman Doctrine through the end of the Cold War.

The Truman Doctrine was first applied to provide aid to which two countries facing communist pressure in 1947?

Answer. Greece and Turkey

Truman asked Congress for aid to Greece, fighting a communist insurgency, and Turkey, facing Soviet pressure over the Dardanelles Straits, establishing the precedent of US support for any nation resisting communism.

How did the Marshall Plan serve US Cold War goals beyond simple humanitarian relief?

Answer. It rebuilt Western European economies to prevent communist parties from gaining power amid postwar poverty and instability.

By funding reconstruction, the US aimed to restore capitalist prosperity and political stability, undercutting the appeal of communism in war-devastated countries like France and Italy.

All 14 questions for Period 8, with the working →

What people get wrong

  1. Treating the Great Society as identical to the New Deal. Instead, note the difference: the New Deal responded to economic collapse with relief and recovery, while the Great Society assumed prosperity and targeted poverty, healthcare, and civil rights through programs like Medicare, Medicaid, and Head Start.
  2. Assuming the civil rights movement ended with the 1965 Voting Rights Act. Instead, track the shift toward Black Power, urban uprisings, and continuing economic and de facto segregation battles into the 1970s.
  3. Describing the Cold War as purely a military standoff. Instead, include the economic and cultural dimensions — the space race, cultural exchange, and competing claims about which system delivered a better standard of living.
  4. Confusing the causes and chronology of Korea and Vietnam. Instead, keep them distinct: Korea (1950–53) began with a conventional cross-border invasion and ended in stalemate near the original border; Vietnam involved a longer counterinsurgency shaped by decolonization and the domino theory.

Period 9: 1980–Present 4–6% of the exam

The conservative resurgence, the end of the Cold War, globalisation, technology, the post-9/11 era.

3 of 14 questions in this unit, with the worked answer

What term describes President Reagan's economic program of large income tax cuts, reduced domestic spending, and deregulation, based on the theory that benefits to investors and businesses would 'trickle down' to the broader economy?

Answer. Reaganomics (supply-side economics)

The theory held that cutting taxes on businesses and high earners would free capital for investment, boosting growth and jobs. In practice it produced strong growth alongside sharply larger federal deficits due to simultaneous increases in defense spending.

Which organization, founded by Jerry Falwell in 1979, mobilized evangelical Christians into conservative politics around issues like opposition to abortion and gay rights?

Answer. The Moral Majority

It was a key part of the New Right coalition that helped elect Reagan in 1980 and pushed social issues onto the national political agenda, alongside fiscal conservatives and neoconservatives.

In the Iran-Contra affair, what two illegal actions did members of the Reagan administration take?

Answer. They secretly sold arms to Iran, violating an arms embargo, and used the profits to fund the Contra rebels fighting Nicaragua's Sandinista government, violating a congressional ban on such aid (the Boland Amendment).

The scandal raised serious questions about unchecked executive power and congressional oversight of foreign policy, echoing earlier debates over presidential war powers.

All 14 questions for Period 9, with the working →

What people get wrong

  1. Treating 'the conservative resurgence' as one unified movement. It was a coalition of fiscal conservatives, religious/social conservatives, and neoconservatives who often disagreed (for example, over defense spending versus overall budget cuts) — name the specific faction relevant to the question rather than 'conservatives' in general.
  2. Explaining the Cold War's end only through US military pressure. The exam expects multi-causal reasoning, so also credit internal Soviet economic stagnation and Gorbachev's reforms as independent, necessary causes.
  3. Confusing the Reagan Doctrine (actively arming anti-communist insurgents to roll back Soviet gains) with the Truman Doctrine or containment (resisting further communist expansion without necessarily reversing existing gains) — state the distinction explicitly when comparing Cold War strategies across periods.
  4. Attaching NAFTA, the dot-com boom, or welfare reform to the Reagan administration by default. NAFTA (1994) and the major internet/tech boom occurred mainly under Clinton — check the decade and president before naming policies.

How it works

Choosing this curriculum creates a course in Chalkset with one study set per unit and the exam date set to the start of the next testing window. Readiness is weighted the way the exam is, so a weak unit that carries 18% of the score pulls harder than one that carries 6%. Pre-written units come with worked explanations and an independently checked answer key; the rest are written by the agent when you open them.
