AP Micro Unit 6 covers 5 topics: socially efficient and inefficient market outcomes, externalities, public and private goods, the effects of government intervention in different market structures, and inequality. Together they build a framework for understanding market failure and when government policy can improve outcomes. Here's the full topic list: - 6.1 Socially Efficient and Inefficient Market Outcomes - 6.2 Externalities - 6.3 Public and Private Goods - 6.4 The Effects of Government Intervention in Different Market Structures - 6.5 Inequality See matched study materials at [AP Micro Unit 6](/ap-micro/unit-6). ### How much of the AP Micro exam is Unit 6? Unit 6 makes up 8-13% of the AP Micro exam. That range covers market failure, public goods, externalities, government intervention, and inequality. It's a smaller unit by topic count (5 topics), but the concepts show up in both multiple-choice and free-response questions, so it's worth knowing them cold. ### What's on the AP Micro Unit 6 progress check (MCQ and FRQ)? The AP Micro Unit 6 progress check in AP Classroom includes both MCQ and FRQ sections drawn from all five unit topics. The MCQ portion tests your ability to identify market failure scenarios, classify public goods versus private goods, and analyze externalities. The FRQ section typically asks you to show deadweight loss from an externality or explain a government policy response. The progress check pulls heavily from 6.1 (socially efficient outcomes), 6.2 (externalities), and 6.3 (public and private goods), so those three topics are your highest-priority prep. Practice with matched questions at [AP Micro Unit 6](/ap-micro/unit-6). ### How do I practice AP Micro Unit 6 FRQs? AP Micro Unit 6 FRQs most often focus on externalities and market failure, asking you to draw a correctly labeled graph showing a negative or positive externality, identify the deadweight loss, and explain a government policy fix like a tax or subsidy. Public goods and inequality questions appear less often but do show up. To practice effectively, work through these steps: 1. Draw the externality graph from scratch, label MSC or MSB, and mark the socially optimal quantity. 2. Explain in writing why the market outcome is inefficient. 3. Describe the corrective policy and its effect on the graph. Find practice FRQs and worked examples at [AP Micro Unit 6](/ap-micro/unit-6). ### Where can I find AP Micro Unit 6 practice questions? The best place to find AP Micro Unit 6 practice questions, including multiple-choice and practice test sets, is [AP Micro Unit 6](/ap-micro/unit-6). You'll find MCQs covering market failure, public goods, and externalities, plus FRQ practice with answer explanations. For a full practice test experience, work through questions from all five topics in order so you can spot which concepts, like classifying goods or graphing externalities, need more review. ### How should I study AP Micro Unit 6? Start with the two highest-yield topics: externalities (6.2) and public and private goods (6.3). These concepts, including market failure, deadweight loss, and the distinction between public goods and private goods, appear most often on both the MCQ and FRQ sections. A solid study plan looks like this: 1. Learn the four good types (public, private, common resource, club) and their excludability and rivalry characteristics. 2. Practice drawing negative and positive externality graphs until labeling MSC, MSB, and the socially optimal quantity is automatic. 3. Study government interventions from 6.4, like taxes, subsidies, and price controls, and connect each to a specific market failure. 4. Review inequality (6.5) with a focus on how it's measured and what policies address it. 5. Do timed FRQ practice and check your graphs against scoring guidelines.
