CoStudy's High School World History bank holds 438 items organised into 12 chapters that follow the published blueprint. Every multiple-choice question carries a written rationale explaining why the correct answer is correct and why each distractor is tempting but wrong, and the bank includes 10 scenario-based simulations.
Each chapter follows a domain of the published exam outline. Practise one on its own:
A sample of 12 multiple-choice questions from the bank, with the full rationale shown.
The Scientific Revolution (~16th–17th c.):
Answer: A — Introduced observation, mathematical analysis, and experimentation — heliocentrism (Copernicus, Kepler, Galileo), Newtonian mechanics, scientific method (Bacon, Descartes); foundational for modern science and the Enlightenment
A) Standard contributions. B/C/D) Each is incorrect.
Which best characterizes Tokugawa Japan's foreign policy for most of 1633-1853?
Answer: C — Strict limits on foreign trade and travel — commonly called sakoku — with narrow contact permitted (notably at Dejima)
Under sakoku, Christianity was suppressed and foreign contact was funneled through a Dutch trading post at Dejima and limited Chinese, Korean, and Ryukyu channels. 'Complete openness' is the classic trap-reversal of the actual policy.
Latin American independence (~1800s):
Answer: C — Haitian Revolution (1791-1804, first successful slave revolution, led by Toussaint L'Ouverture); Latin American wars led by Bolívar (Venezuela, Colombia, etc.), San Martín (Argentina, Chile); Brazil independence from Portugal 1822; broke Spanish/Portuguese colonial rule; new nations faced challenges (economic, political instability)
C) Standard. A/B/D) Each is incorrect.
The Russian Revolution of 1917 brought to power which political movement?
Answer: B — Bolshevik communism under Lenin
The October Revolution of 1917 brought the Bolsheviks, led by Lenin, to power, establishing the world's first communist state — later the Soviet Union (1922).
The Edict of Milan (313 CE) is significant because it:
Answer: A — Legalized the practice of Christianity throughout the Roman Empire
Constantine and Licinius legalized (tolerated) Christianity in 313 CE. 'Made Christianity the sole official religion' is the classic trap: that step came later under Theodosius I in 380 CE with the Edict of Thessalonica.
Stalin's Five-Year Plans in the USSR (from 1928) aimed to:
Answer: B — Rapidly industrialize and collectivize agriculture at enormous human cost, including famine in Ukraine (Holodomor)
Forced-pace industrialization coincided with collectivization, deportations, and famine (1932-33). 'Market economy modeled on the U.S.' is the classic trap-reversal that inverts Stalin's economic program.
NATO was founded in:
Answer: A — 1949, as a mutual-defense alliance among the U.S., Canada, and western European states
The Washington Treaty of 1949 established NATO. '1955' is the classic trap-reversal — that is when the Warsaw Pact formed in response to West Germany joining NATO, not when NATO itself began.
The unification of Germany in 1871 was engineered chiefly by:
Answer: B — Otto von Bismarck, through the diplomacy and wars of Prussia
Bismarck maneuvered Prussia into wars with Denmark, Austria, and France that culminated in the proclamation of the German Empire at Versailles. Wilhelm II is the classic trap because his name is famous, but he inherited the empire; he did not build it.
Industrial Revolution global impact:
Answer: A — Spread from Britain (1750+) globally; transformed economies, urbanization, colonialism (Europe imperial expansion via tech), labor movements
A) Standard. B/C/D) Each is incorrect.
European imperialism in the 19th century was driven by:
Answer: D — Economic motives (raw materials, markets), nationalism, missionary impulse, and racial ideologies
D) Standard multi-causal interpretation. A/B/C) Each contradicts the record.
The Mughal Empire in India is best associated with which of the following rulers?
Answer: C — Akbar the Great, who consolidated the empire and pursued religious tolerance
Akbar (r. 1556-1605) expanded and centralized the empire and reduced sectarian taxes on non-Muslims. The Suleiman trap conflates two contemporaneous Muslim rulers of different empires — Ottoman and Mughal.
The Maya civilization is best known for:
Answer: C — Fully developed writing, complex mathematics, and accurate astronomical calendars
Classic Maya cities left glyphic inscriptions, a place-value number system with zero, and precise astronomical tables. 'Single unified empire' is the classic trap because Maya civilization was a network of independent city-states, not one empire.
6 sample cards from the 150 in the bank.
Who was Mohandas Gandhi assassinated by, and when?

What was the 'Scramble for Africa'?
Late 19th-century rapid colonization of nearly all of Africa by European powers, formalized at the Berlin Conference (1884–85).
What was the Arab Spring (2010–2012)?
Wave of pro-democracy uprisings across the Middle East and North Africa; toppled regimes in Tunisia, Egypt, Libya, and Yemen.
What was the encomienda system?
Spanish colonial labor system that granted colonists the right to extract labor and tribute from Native peoples — a brutal form of forced labor.

1793–94 phase of the French Revolution under Robespierre when ~17,000 people were executed by guillotine.
What was the Sepoy Rebellion (1857)?
Major uprising against the British East India Company in India; led to direct British Crown rule (the British Raj).

Yes. Every multiple-choice item carries a written rationale that states the controlling principle behind the correct answer and then addresses each wrong option in turn — why it tempts and precisely where it fails. Knowing why the plausible answer was wrong is worth more than knowing which letter was right.
It is organised into 12 chapters that follow the published exam blueprint: Early Civilizations and the Ancient World; Classical Empires: Greece, Rome, Han China, Maurya/Gupta India; Post-Classical Era: Byzantium, Islamic World, Medieval Europe, East Asia; The Americas Before 1500: Mesoamerica, Andes, North America; Renaissance, Reformation, and the Age of Exploration; Gunpowder Empires: Ottoman, Safavid, Mughal; Enlightenment and Atlantic Revolutions; Industrialization and Imperialism; World War I and the Interwar Era; World War II; Cold War and Decolonization; Contemporary World and Globalization. The number of questions in each chapter is proportional to that domain's published weight, so working through the bank exposes you to roughly the mix the real exam uses.

Last reviewed 2026-08-22. Banks are written against the certifying body's published exam outline and re-checked when that outline changes — exams get renumbered, retired and reweighted, and a bank written to a superseded outline teaches the wrong proportions. Figures that are re-indexed annually are deliberately not asserted as rules; the questions test the governing principle instead.
