U.S. History
Summary
U.S. History on the GED focuses on major turning points — events that fundamentally changed the nation's direction. You must understand causes, effects, and the connections between events, not just memorize dates and names.
Key Periods and Concepts
#### Westward Expansion (Early–Mid 1800s)
• Manifest Destiny: The 19th-century belief that U.S. expansion to the Pacific Ocean was inevitable and divinely justified
- Consequences: displacement of Native Americans, wars with Mexico, growth of slavery debate into new territories
• Louisiana Purchase (1803): Napoleon sold ~828,000 square miles to the U.S. for approximately $15 million
- Effect: roughly doubled U.S. territory and opened westward expansion
#### The Civil War Era (1861–1865)
• Root Cause: Slavery — specifically its expansion into new territories — created irreconcilable economic and political divisions
- The South's agrarian, slave-based economy vs. the North's industrialized, wage-labor economy
• Emancipation Proclamation (1863):
- Declared enslaved people in Confederate states free
- Did not free enslaved people in border states loyal to the Union
- Shifted the war's moral purpose to include abolition
- Discouraged European nations from supporting the Confederacy
#### Reconstruction and the Gilded Age (1865–1900)
• 14th Amendment (1868): Granted citizenship, equal protection, and due process — crucial for understanding later civil rights developments
• Gilded Age: Period of rapid industrialization, corporate monopolies, and extreme wealth inequality
- Robber Barons: Wealthy industrialists (Carnegie, Rockefeller) who built monopolies/trusts
- Stark contrast between industrial wealth and harsh conditions for the working poor
#### The Great Depression and New Deal (1929–1939)
• Great Depression: Triggered by the 1929 stock market crash; characterized by massive unemployment and economic collapse
• New Deal (FDR): Three goals — Relief, Recovery, Reform
- Created jobs programs, banking regulations, and social safety nets (e.g., Social Security)
#### Civil Rights Movement and Brown v. Board (1954)
• Plessy v. Ferguson (1896): Established the "separate but equal" doctrine, legalizing racial segregation
• Brown v. Board of Education (1954): Supreme Court overturned Plessy, ruling racial segregation in public schools unconstitutional
- Landmark legal principle: separate is inherently unequal
#### Post-WWII America and the Cold War
• Marshall Plan: U.S. provided $12+ billion to rebuild Western European economies after WWII
- Dual purpose: humanitarian aid AND preventing the spread of communism
- Example of U.S. foreign policy shaped by Cold War ideological competition
Key Terms — U.S. History
• Manifest Destiny — belief in inevitable westward expansion
• Emancipation Proclamation — 1863 executive order freeing enslaved people in Confederate states
• New Deal — FDR's programs for relief, recovery, and reform during the Great Depression
• Monopoly/Trust — a company or group controlling an entire industry
• Marshall Plan — post-WWII U.S. aid program for European reconstruction
• Segregation — forced separation by race
• Reconstruction — period after the Civil War rebuilding the South and integrating formerly enslaved people
Watch Out For ⚠️
• The Emancipation Proclamation did not free all enslaved people — only those in states actively rebelling. The 13th Amendment (1865) formally abolished slavery nationwide.
• The Civil War's causes were complex, but the GED emphasizes slavery as the central cause, not simply "states' rights."
• Brown v. Board overturned Plessy v. Ferguson — know both cases and the connection between them.
• The Louisiana Purchase was from France, not Britain or Spain.
• The New Deal addressed the Great Depression, not WWI or WWII.

Civics & Government
Summary
This section tests your understanding of how the U.S. government is structured and how it functions. Focus on the relationships between the branches, the role of the Constitution, and key amendments.
Structure of the Federal Government
#### The Three Branches
| Branch | Body | Primary Function |
|---|---|---|
| Legislative | Congress (House + Senate) | Makes laws |
| Executive | President | Enforces laws |
| Judicial | Supreme Court | Interprets laws |
#### Checks and Balances
Each branch holds specific powers over the others to prevent any single branch from becoming too powerful:
• Congress can override a presidential veto with a 2/3 vote in both chambers
• The President can veto legislation passed by Congress
• The Supreme Court can declare laws unconstitutional (judicial review)
• The Senate must confirm presidential appointments and ratify treaties
#### How a Bill Becomes a Law
1. Bill introduced in Congress (House or Senate)
2. Debated and revised in committee
3. Voted on in both the House and Senate
4. If passed, sent to the President
5. President signs (becomes law) or vetoes (rejects)
6. A veto can be overridden by a two-thirds majority in both chambers
Foundational Documents and Concepts
#### The Constitution and Federalism
• Federalism: Division of power between the federal government and state governments
- Federal powers: foreign policy, currency, military
- State powers: education, local law enforcement, marriage laws
- Shared powers: taxation, law enforcement
#### The Bill of Rights (First 10 Amendments)
Ratified in 1791 to guarantee individual liberties:
• 1st: Freedom of speech, religion, press, assembly, petition
• 2nd: Right to bear arms
• 4th: Protection against unreasonable searches and seizures
• 5th: Right against self-incrimination; due process
• 6th: Right to a speedy trial
#### The 14th Amendment (1868)
• Granted citizenship to all born or naturalized in the U.S.
• Guaranteed equal protection under the law
• Guaranteed due process rights
• Originally aimed at protecting formerly enslaved people; later used to extend civil rights broadly
The Impeachment Process
• Impeachment: The House of Representatives formally charges the president with misconduct (a majority vote)
• The Senate then holds a trial; a two-thirds vote is required to remove the president
• Impeachment ≠ removal; a president can be impeached but remain in office
Key Terms — Civics & Government
• Checks and balances — system preventing any one branch from having total power
• Federalism — shared power between national and state governments
• Veto — president's power to reject legislation
• Impeachment — formal charge of misconduct by the House
• Judicial review — Supreme Court's power to strike down unconstitutional laws
• Bill of Rights — first 10 amendments guaranteeing individual rights
• Amendment — formal change or addition to the Constitution
• Due process — legal guarantee of fair treatment under the law
Watch Out For ⚠️
• Impeachment does not mean removal from office. The House impeaches; the Senate convicts and removes.
• A presidential veto requires a two-thirds vote to override — not a simple majority.
• The Bill of Rights is the first ten amendments — not the entire Constitution.
• Federalism means power is shared — neither the federal nor state government holds all power.
• The 14th Amendment is one of the most referenced amendments — connect it to civil rights, citizenship, and equal protection questions.

Economics
Summary
GED Economics focuses on fundamental concepts: how markets work, how the economy is measured, and the role of government in economic activity. Understand the vocabulary and relationships between concepts rather than memorizing formulas.
Core Economic Concepts
#### Supply, Demand, and Prices
• Law of Supply and Demand: The price of a good is determined by its availability (supply) and consumer desire (demand)
| Condition | Effect on Price |
|---|---|
| Demand increases / Supply stays same | Price rises |
| Demand decreases / Supply stays same | Price falls |
| Supply decreases / Demand stays same | Price rises |
| Supply increases / Demand stays same | Price falls |
#### Opportunity Cost
• Opportunity cost: The value of the next best alternative you give up when making a decision
- Example: If you spend $1,000 on a vacation instead of investing it, the opportunity cost is the return you would have earned on the investment
- Key insight: Every choice involves a trade-off
#### Measuring the Economy
• Gross Domestic Product (GDP): The total monetary value of all goods and services produced within a country in a given time period
- Used as the primary measure of a nation's economic health
- Rising GDP = growing economy; falling GDP = shrinking economy
#### Recession vs. Depression
| Term | Definition |
|---|---|
| Recession | Significant economic decline lasting at least two consecutive quarters (6 months) |
| Depression | A severe and prolonged recession with extremely high unemployment and sharp GDP decline |
• Think of a depression as a recession that becomes much deeper and longer-lasting (e.g., the Great Depression of the 1930s)
#### Inflation
• Inflation: A general rise in the price level of goods and services over time
• Effect on purchasing power: As prices rise, each dollar buys less
- Example: If inflation is high, a $20 bill that once bought a full bag of groceries now buys less
• Deflation (opposite): Prices fall, but can also signal economic trouble
Types of Economic Systems
| System | Decision-Making | Government Role | Example |
|---|---|---|---|
| Market Economy | Individuals and businesses via supply & demand | Minimal | United States |
| Command Economy | Government controls production and prices | Total control | North Korea, Soviet Union |
| Mixed Economy | Combination of market and government intervention | Moderate | Most modern nations |
The Federal Reserve
• Federal Reserve ("The Fed"): The central bank of the United States
• Manages monetary policy — controlling money supply and interest rates
• Three primary goals:
1. Maximum employment
2. Stable prices (controlling inflation)
3. Moderate long-term interest rates
• Tools: Raising/lowering interest rates; buying/selling government securities
Key Terms — Economics
• GDP (Gross Domestic Product) — total value of goods/services produced in a country
• Inflation — rising price levels; decreases purchasing power
• Recession — economic decline for 6+ months
• Depression — severe, prolonged economic collapse
• Opportunity cost — value of the best alternative foregone
• Supply — amount of a good available in the market
• Demand — consumer desire for a good
• Federal Reserve — U.S. central bank managing monetary policy
• Market economy — private-driven economic decisions
• Command economy — government-controlled economic decisions
• Monetary policy — government/central bank management of money supply and interest rates
Watch Out For ⚠️
• A recession requires two consecutive quarters of decline — know this specific definition.
• Inflation reduces purchasing power — more dollars are needed to buy the same goods.
• The Federal Reserve controls monetary policy (money supply/interest rates). Fiscal policy (taxes and government spending) is controlled by Congress and the President — don't confuse the two.
• In a market economy, the government has minimal control; in a command economy, it has total control. Most real economies are mixed.
• Opportunity cost is about trade-offs, not just the money spent — it's what you give up.

Geography & World Studies
Summary
Geography on the GED includes both physical geography and the study of how humans interact with their environments, as well as key events in world history. Understanding geographic concepts helps explain historical patterns of settlement, trade, and conflict.
The Five Themes of Geography
| Theme | Core Question | Example |
|---|---|---|
| Location | Where is it? | Absolute (coordinates) or relative (near the coast) |
| Place | What is it like? | Physical features, climate, culture, language |
| Human-Environment Interaction | How do people and environments affect each other? | Building dams, deforestation, irrigation |
| Movement | How do people, goods, and ideas move? | Migration, trade routes, internet |
| Region | What areas share common characteristics? | The Bible Belt, the Rust Belt, the Sahara |
Key Reference Points on World Maps
• Equator (0° latitude): Divides Earth into Northern and Southern Hemispheres
• Prime Meridian (0° longitude): Divides Earth into Eastern and Western Hemispheres
• Together, these create a coordinate system for locating any place on Earth
• Latitude lines run horizontally (east-west); Longitude lines run vertically (north-south)
Major World Historical Events
#### The Silk Road
• Ancient network of trade routes connecting East Asia, Central Asia, and Europe
• Traded goods: silk, spices, precious metals, textiles
• More than trade: spread of religions (Buddhism, Islam, Christianity), languages, technologies, and ideas
• Example of Movement and Human-Environment Interaction themes
#### The Industrial Revolution
• Transformed economies from agriculture-based to factory/manufacturing-based
• Urbanization: Massive migration from rural areas to cities for factory work
• Effect on population distribution: Population concentrated in urban centers
• Connected to the rise of the Gilded Age in the United States
#### The Cold War (1947–1991)
• Cold War: Geopolitical tension between the United States (capitalism/democracy) and the Soviet Union (communism/authoritarianism)
• "Cold" because the two superpowers never directly fought each other militarily
• Key features:
- Arms race: Competition to build nuclear weapons
- Proxy wars: Each side supported opposing forces in conflicts in Korea, Vietnam, and elsewhere
- Space race: Competition for technological and scientific dominance
• Ended with the dissolution of the Soviet Union in 1991
• Connected to the Marshall Plan (U.S. preventing communist spread in Europe)
#### The United Nations (UN)
• Founded in 1945 after WWII to prevent future global conflicts
• Primary purposes:
- Maintain international peace and security
- Promote human rights
- Foster international cooperation
- Address global challenges: poverty, climate change, disease
Key Terms — Geography & World Studies
• Five Themes of Geography — Location, Place, Human-Environment Interaction, Movement, Region
• Equator — 0° latitude; divides Northern and Southern Hemispheres
• Prime Meridian — 0° longitude; divides Eastern and Western Hemispheres
• Urbanization — movement of population from rural to urban areas
• Cold War — U.S.-Soviet ideological and geopolitical rivalry (1947–1991)
• Proxy war — conflict where superpowers support opposing sides without direct confrontation
• Silk Road — ancient trade network connecting Asia and Europe
• United Nations — international organization for peace and cooperation (founded 1945)
• Capitalism — private ownership and market-based economy
• Communism — government ownership and command-based economy
Watch Out For ⚠️
• Latitude runs horizontally and measures north/south; Longitude runs vertically and measures east/west. Students commonly mix these up.
• The Prime Meridian divides East/West; the Equator divides North/South — not the other way around.
• The Cold War was not a direct military conflict between the U.S. and USSR — it was ideological and economic competition with proxy conflicts.
• The Silk Road was as important for spreading ideas and culture as it was for trading physical goods.
• The UN was founded in 1945 (post-WWII) — different from the League of Nations, its failed predecessor after WWI
