AP Macroeconomics Course Framework and Components

The AP Macroeconomics Course and Exam Description (CED) is divided into 2 main components - course skills and course content. When you go through the 6 units, you will acquire the essential course skills to pass the exam. Combined, these 2 components prepare you to have a solid foundation in concepts and help you succeed on the AP Macroeconomics exam.

Each of the 6 units is further based on the 4 big ideas that provide the course’s foundation. Before you start preparing for the AP Macroeconomics course, take time to understand the prerequisites and exam information. 

Course Skills for AP Macroeconomics

Mastering the AP Macro course requires you to learn a series of course skills listed by the College Board. The course combines these practices with the course content you learn in class, so you can use these skills during the AP exam. Let's see what these AP Macroeconomics course skills are:

  1. Principles and Models

    The first-course skill requires you to identify and describe economic concepts, principles, or models and illustrate your understanding through examples, quantitative data, or calculations. In addition to analyzing these AP Macroeconomics key concepts, you’ll also need to describe their similarities, differences, and limitations.

  2. Interpretation

    The second skill builds off of the first one and requires you to explain specific economic outcomes using concepts, principles, or models.

  3. Manipulation

    While the previous skill focuses on explaining a given outcome, this course skill requires you to determine an outcome(s) using the AP Macroeconomics key concepts, models, and quantitative data presented to you.

  4. Graphing and Visuals

    To master the final skill, you’ll have to successfully draw accurately labeled graphs and charts to represent an economic situation presented to you. You’ll need to take into account any changes to that economic situation before representing it through your model or graph.

The 4 Big Ideas of AP Macroeconomics

The big ideas are the fundamental themes of the AP Macroeconomics curriculum. Each unit and topic you learn covers 1 or more of these recurring themes. The AP Macro course consists of 4 big ideas; let’s learn about each of them below:

  1. Big Idea 1: Economic Measurements (MEA)

    These are metrics developed by economists to measure and observe the condition of an economy and assess its progress over time. Governments, companies, and individuals frequently use these measurements to shape policies, make business decisions, and inform personal decisions.

  2. Big Idea 2: Markets (MKT)

    This big idea includes the concept of markets. You’ll learn how buyers and sellers come together to trade goods and services, benefiting both parties in competitive markets. The basic concept of supply and demand can be applied in various market settings.

  3. Big Idea 3: Macroeconomic Models (MOD)

    Under this big idea, you’ll learn about macroeconomic models and how they can be used to forecast and explain fundamental economic connections. You will also learn about their relationship with economic disruptions.

  4. Big Idea 4: Macroeconomic Policies (POL)

    The fourth big idea concerns the relationship between government taxation and spending policies and a country’s central bank's monetary policies. It also addresses how these policies affect the economy's output, pricing structures, and employment level in the short and long terms.

The 6 Units of AP Macroeconomics and Topics Covered

The course content is logically organized into 6 units, each with varying weight on the exam, and each unit is broken down into several topics. These units, along with the big ideas and course skills, are designed to help you build a solid foundation for college-level macroeconomics and prepare for the AP Macroeconomics exam.

UNIT 1: Basic Economic Concepts

Exam Weighting: 5 – 10% | Class periods ~ 8 – 10

Big Ideas Incorporated:
  1. Big Idea 2: Markets (MKT)

    1. What is resource scarcity, and why do people and societies need to trade?
    2. What determines the market price for a good or service?
  2. Big Idea 3: Macroeconomic Models (MOD)

    How do models like the production possibilities curve (PPC) help us determine tradeoffs, scarcity, employment, and economic growth?

Unit 1 will introduce you to fundamental concepts in economics, like markets, supply and demand, and the exchange of resources. You’ll learn models and concepts that you’ll apply in subsequent units.

In this unit, you’ll learn:

  • Most resources are scarce, and people must make choices to prioritize access to some of them, thus creating trade-offs and a cycle of supply and demand. Topics 1.1 - 1.5
  • How supply and demand impact market equilibrium and the price of a resource or service: Topic 1.6

UNIT 2: Economic Indicators and the Business Cycle

Exam Weighting: 12 – 17% | Class periods ~ 9 – 11

Big Idea Incorporated:

Big Idea 1: Economic Measurements (MEA)

  1. What are the indicators of a healthy or poor economy?
  2. How does money flow inside an economic system to create the cycle of income and expenditure?

Unit 2 will use the macroeconomic concepts you learned in Unit 1 and teach you to apply those concepts to understand the circular flow of money, GDP, unemployment, inflation, and business cycles.

In this unit, you’ll learn to:

  • Describe economic concepts, principles, and models to understand GDP and unemployment: Topics 2.1 - 2.3
  • How macroeconomic models are used to determine inflation, business cycles, and the overall health of a country’s economy: Topics 2.4 - 2.7

UNIT 3: National Income and Price Determination

Exam Weighting: 17 – 27% | Class periods ~ 10 – 12

Big Ideas Incorporated:

  1. Big Idea 3: Macroeconomic Models (MOD)

    How do the choices people make about spending and producing things impact the economy? This includes decisions made by households, businesses, the government, and other countries.
  2. Big Idea 4: Macroeconomic Policies (POL)

    1. Who determines the price of products and services in an economy?
    2. How do taxation policies and the choices made by the government about spending money affect a country’s economy?

In this unit, you will learn about an economic model called the aggregate demand–aggregate supply model. This model helps economists understand how different factors, such as spending decisions, production choices, economic fluctuations, and government policies, affect important economic measures such as output, income, unemployment, and inflation.

Topics covered in this unit include:

  • Learning and understanding how the aggregate supply model is used to determine production decisions, economic fluctuations, and policy actions on macroeconomic outcomes, including output, income, unemployment, and inflation: Topics 3.1 - 3.8
  • Exploring the effects of a government’s fiscal policy on the country’s economy: Topic 3.9

UNIT 4: Financial Sector

Exam Weighting: 18 – 23% | Class periods ~ 11 - 13

    1. Why does the price of one nation’s currency relative to another nation’s currency fluctuate?
    2. How do changes in the value of a country’s currency impact its economy?

In Unit 6, you’ll explore the concept of an open economy where countries interact with the world through product and financial markets, including currency exchange rates. You’ll also learn how economic activity affects currency supply, demand, and value.

Topics covered:

  • Balance of payments accounts: Topic 6.1
  • Currency exchange rates, foreign exchange market, and the effects of fiscal policy on the exchange market: Topics 6.2 - 6.5
  • Interest rates and the flow of capital across countries: Topic 6.6

Frequently Asked Questions (FAQs)

The most important AP Macroeconomics topics are usually the ones with the most questions on the exam. Per the College Board, the majority of multiple-choice questions cover the following three units:
  • Unit 5: Long-Run Consequences of Stabilization Policies
  • Unit 4: Financial Sector
  • Unit 3: National Income and Price Determination
Yes, you can take the AP Macroeconomics exam without taking the course.

Many students report that Unit 3: National Income and Price Determination and Unit 4: Financial Sector are the most challenging units in AP Macroeconomics. In particular, Unit 4 is often considered the hardest because it introduces several new concepts related to banking, the money supply, and monetary policy.

This unit requires you to understand topics such as money creation, the money market, interest rates, and central bank policy tools. Questions often involve interpreting graphs and explaining how changes in the financial system affect the broader economy. Because these ideas build on earlier units and involve multiple steps of reasoning, students may need extra practice to fully master them.

In most high schools, AP Macroeconomics is offered as a one-semester course. Schools often pair it with AP Microeconomics, allowing students to study both subjects during the same academic year. While AP courses themselves are not automatically dual credit, many colleges may award college credit or placement if you earn a qualifying score on the AP Macroeconomics exam.
AP Macroeconomics is generally equivalent to an introductory college-level macroeconomics course, often called Principles of Macroeconomics or Introductory Macroeconomics. If you earn a qualifying AP score, many colleges allow you to skip this introductory course and move directly into more advanced economics classes.
