# AP Microeconomics exam guide > Six units of firm and market analysis, from elasticity through market failure, with the cost curves and market-structure graphs the exam demands. - Canonical page: https://www.arcadesacademy.com/exams/ap-microeconomics - Markdown source: https://www.arcadesacademy.com/exams/ap-microeconomics/llms.txt - Exam family: AP exams - Governing body: College Board - Official exam information: https://apstudents.collegeboard.org/courses/ap-microeconomics - Who takes it: High school students taking AP Microeconomics who want college credit or placement and a foundation for business, economics, or policy study. - Follows the fall 2026 course and exam description, from 4 May 2027 - Guide structure last checked against official sources: August 30, 2026 ## Overview AP Microeconomics studies the decisions of individual consumers, firms, and markets: how prices are set, how firms choose output, how market structure changes outcomes, and when markets fail to allocate resources efficiently. The course is model-heavy and cumulative, since the cost curves built in Unit 3 reappear in every market structure that follows. The exam rewards graphical fluency above all. Free-response questions typically ask for a correctly labeled graph, an identification of a profit-maximizing quantity or an efficiency loss, and a written explanation of why the result follows. Perfect competition, monopoly, monopolistic competition, oligopoly, and factor markets each have a standard diagram students should be able to draw from memory.

Free responses are scored with published point-based rubrics that award credit for correct graphs, correct identifications, and correct explanations, and the composite is converted to the 1 to 5 AP scale. ## Units AP Microeconomics is organized into 6 units. Each one below lists its published weighting where the governing body publishes one, the topics it covers, and study tips specific to it. ### 1. Unit 1: Basic Economic Concepts - Position: 1 of 6 - Page: https://www.arcadesacademy.com/exams/ap-microeconomics/unit-1-basic-economic-concepts Unit 1 introduces scarcity, opportunity cost, the production possibilities curve, and comparative advantage. It also establishes marginal analysis as the decision rule the rest of the course applies. The concepts are shared with AP Macroeconomics, but the applications quickly diverge. #### Topics - **Scarcity and opportunity cost** — Limited resources against unlimited wants, and cost measured as the value of the next best alternative forgone. - **Economic systems and resource allocation** — How different systems answer what, how, and for whom to produce, and the role of prices as signals. - **The production possibilities curve** — Efficiency and attainability, increasing opportunity cost from resource specialization, and shifts from growth. - **Comparative advantage and gains from trade** — Calculating opportunity cost per unit and identifying terms of trade that benefit both parties. - **Marginal analysis and consumer choice** — Comparing marginal benefit with marginal cost, diminishing marginal utility, and the utility-maximizing rule. #### Study tips - Practice the utility-maximizing rule numerically, since it appears in short free-response prompts. - Learn to compute comparative advantage both per unit of output and per unit of input. - Treat marginal analysis as the default reasoning tool for the entire course, not a Unit 1 topic. ### 2. Unit 2: Supply and Demand - Position: 2 of 6 - Page: https://www.arcadesacademy.com/exams/ap-microeconomics/unit-2-supply-and-demand Unit 2 develops the supply and demand model, elasticity, and the welfare effects of government intervention. Consumer and producer surplus and deadweight loss are introduced here and reused in every later unit. Elasticity calculations and interpretations are among the most reliably tested skills in the course. #### Topics - **Demand and supply** — The law of demand and supply, the determinants that shift each curve, and movement along versus shifts. - **Price elasticity of demand** — Calculating and interpreting elasticity, elastic and inelastic ranges, and the relationship to total revenue. - **Other elasticities** — Price elasticity of supply, income elasticity distinguishing normal from inferior goods, and cross-price elasticity for substitutes and complements. - **Market equilibrium and changes** — Surpluses and shortages, simultaneous shifts, and predicting which of price or quantity is indeterminate. - **Consumer and producer surplus** — Measuring welfare on the graph, total surplus at efficient equilibrium, and deadweight loss when quantity deviates. - **Government intervention in markets** — Binding price ceilings and floors, per-unit taxes and subsidies, and how elasticity determines tax incidence. - **International trade and public policy** — World price, imports and exports, and the welfare effects of tariffs and quotas. #### Study tips - Shade surplus and deadweight loss areas on practice graphs until identifying them is instant. - Practice simultaneous-shift questions and state clearly which variable is indeterminate. - Connect tax incidence to relative elasticity rather than memorizing which side pays more. ### 3. Unit 3: Production, Cost, and the Perfect Competition Model - Position: 3 of 6 - Page: https://www.arcadesacademy.com/exams/ap-microeconomics/unit-3-production-cost-and-the-perfect-competition-model Unit 3 builds the firm's cost structure from the production function and then applies it to perfectly competitive markets. Short-run and long-run equilibrium, entry and exit, and shutdown decisions all follow from the cost curves. Everything in Unit 4 assumes these graphs, so mastery here is non-negotiable. #### Topics - **The production function** — Total, average, and marginal product, and the law of diminishing marginal returns in the short run. - **Short-run production costs** — Fixed and variable costs, average total, average variable, and marginal cost, and the relationships among the curves. - **Long-run costs** — The long-run average cost curve, economies and diseconomies of scale, and constant returns to scale. - **Types of profit** — Explicit and implicit costs, and the difference between accounting profit and economic profit. - **Profit maximization** — The marginal revenue equals marginal cost rule and how to identify profit or loss on the graph. - **Short-run supply and shutdown decisions** — Producing at a loss versus shutting down, and why marginal cost above average variable cost is the firm's supply curve. - **Perfect competition in the long run** — Entry and exit driving economic profit to zero, and productive and allocative efficiency at long-run equilibrium. #### Study tips - Draw the full cost-curve family repeatedly until marginal cost cuts both average curves at their minimums automatically. - Practice side-by-side market and firm graphs, since perfect competition questions almost always require both. - Distinguish accounting from economic profit in words; free-response prompts frequently test the difference. ### 4. Unit 4: Imperfect Competition - Position: 4 of 6 - Page: https://www.arcadesacademy.com/exams/ap-microeconomics/unit-4-imperfect-competition Unit 4 covers monopoly, monopolistic competition, and oligopoly, contrasting each with the perfectly competitive benchmark. Price-making behavior, deadweight loss, and long-run outcomes differ across structures in ways the exam tests directly. Game theory provides the analytical tool for oligopoly. #### Topics - **Introduction to imperfectly competitive markets** — Barriers to entry, price-making power, and how the demand curve facing the firm differs from perfect competition. - **Monopoly** — Marginal revenue below price, profit-maximizing output and price, deadweight loss, and natural monopoly regulation. - **Price discrimination** — Conditions required for price discrimination and its effects on output, surplus, and profit. - **Monopolistic competition** — Product differentiation, short-run profit, and long-run zero economic profit with excess capacity. - **Oligopoly** — Interdependence, collusion and cartels, and why oligopoly outcomes are difficult to predict from structure alone. - **Game theory** — Payoff matrices, dominant strategies, Nash equilibrium, and the prisoner's dilemma applied to firm behavior. - **Comparing market structures** — Efficiency, price, output, and long-run profit across the four structures as a single comparison. #### Study tips - Keep a four-column comparison of market structures on price, output, efficiency, and long-run profit. - Solve payoff matrices by checking each player's best response, one at a time, every time. - Practice shading deadweight loss under monopoly, a recurring free-response task. ### 5. Unit 5: Factor Markets - Position: 5 of 6 - Page: https://www.arcadesacademy.com/exams/ap-microeconomics/unit-5-factor-markets Unit 5 applies supply and demand to markets for labor and other productive resources. Derived demand and marginal revenue product explain why firms hire, and monopsony shows what happens when a single buyer dominates. The graphs mirror product markets, which makes the analogy worth learning explicitly. #### Topics - **Introduction to factor markets** — Derived demand for resources, and the difference between product markets and factor markets. - **Marginal revenue product** — The value of an additional unit of a factor and the hiring rule that sets marginal revenue product equal to factor price. - **Changes in factor demand and supply** — Productivity, output price, and substitute factors shifting demand, and the determinants of factor supply. - **Perfectly competitive labor markets** — Market wage determination and the individual firm's horizontal factor supply curve. - **Monopsony** — A single buyer facing an upward-sloping factor supply curve, and the resulting lower wage and employment. - **Least-cost hiring across factors** — Allocating spending among factors so the marginal product per dollar is equal across inputs. #### Study tips - Map each factor-market graph onto its product-market analogue to cut memorization in half. - Practice monopsony graphs specifically; the extra marginal factor cost curve is easy to omit. - State the hiring rule in words before drawing, since explanations carry rubric points. ### 6. Unit 6: Market Failure and the Role of Government - Position: 6 of 6 - Page: https://www.arcadesacademy.com/exams/ap-microeconomics/unit-6-market-failure-and-the-role-of-government Unit 6 covers externalities, public goods, and inequality, along with the policy tools intended to address them. Socially optimal versus market outcomes and the resulting deadweight loss are the core graphical analysis. The unit closes the course by asking when government intervention improves efficiency and when it does not. #### Topics - **Efficient and inefficient market outcomes** — Allocative efficiency where marginal social benefit equals marginal social cost, and the deadweight loss when it is not. - **Negative externalities** — Costs imposed on third parties, overproduction relative to the social optimum, and corrective taxation. - **Positive externalities** — Benefits accruing to third parties, underproduction relative to the social optimum, and subsidies as a remedy. - **Public goods and common resources** — Non-rivalry and non-excludability, free riding, and the tragedy of the commons. - **Government intervention across market structures** — Antitrust policy, regulation of natural monopoly, and the trade-offs of intervening in imperfect markets. - **Income and wealth inequality** — The Lorenz curve and Gini coefficient, sources of inequality, and redistributive policy tools. #### Study tips - Draw externality graphs with both private and social curves and label the socially optimal quantity every time. - Practice explaining why the market fails rather than only identifying that it does. - Contrast public goods with common resources using excludability and rivalry as the two axes. ## Study strategies - Rebuild the cost-curve family and each market-structure graph from a blank page several times a week; nearly every free-response question begins with one. - Answer free-response prompts in rubric order, drawing the graph first, then identifying the quantity or area, then explaining. - Use the 10-minute reading period to sketch graphs and underline the task verbs before writing anything. - Practice elasticity and surplus calculations under time, since arithmetic slowness costs multiple-choice points. - Compare all four market structures on one page and review that page weekly rather than studying each structure in isolation. - If you also take AP Macroeconomics, keep separate vocabulary notes, because shared terms carry different meanings across the two courses. ## Frequently asked questions ### How is the AP Microeconomics exam structured? Section I is 60 multiple-choice questions in 70 minutes, worth two-thirds of the score. Section II is 3 free-response questions in 60 minutes, beginning with a 10-minute reading period and worth one-third of the score. ### How much of the exam is graphs? Most free-response questions require at least one correctly labeled graph, and many multiple-choice questions present or imply one. Graphing accuracy is the highest-leverage skill in the course. ### Should I take Micro before Macro? Either order works, and the courses share Unit 1. Some students find Micro's firm-level logic a natural foundation, while others prefer Macro's policy focus first; schools often teach them in a single year. ### Do I need calculus? No. AP Microeconomics uses arithmetic, ratios, and graph interpretation. Marginal analysis is presented through tables and graphs rather than derivatives. ### Is the exam given on a computer? Recent administrations have used a hybrid format, with multiple-choice questions in College Board's Bluebook application and free-response work, including graphs, completed on paper. Confirm the format for your exam year on the official course page. ## Related exam guides - [AP Macroeconomics](https://www.arcadesacademy.com/exams/ap-macroeconomics): Six units of models and graphs, from the production possibilities curve to the foreign exchange market, drilled the way the free-response section asks for them. - [AP Calculus AB](https://www.arcadesacademy.com/exams/ap-calculus-ab): All eight AP Calculus AB units with published exam weightings, from limits through applications of integration. - [AP Statistics](https://www.arcadesacademy.com/exams/ap-statistics): The revised five-unit AP Statistics framework, from exploring data and collecting it through inference and regression. - [AP United States Government and Politics](https://www.arcadesacademy.com/exams/ap-us-government-and-politics): Five units, nine foundational documents, and fifteen required Supreme Court cases, organized the way the exam asks about them. ## Independence and trademark notice AP® is a registered trademark of College Board, which was not involved in the production of, and does not endorse, this site.
