AP Microeconomics covers 6 units, from Basic Economic Concepts to Market Failure and the Role of Government. Use this hub for unit study guides, topic review, practice questions, FRQs, key terms, cheatsheets, score calculators, practice exams, and exam prep.
AP Microeconomics studies how people and firms make choices under scarcity, using graphs and marginal analysis to explain prices, production, market structures, and the role of government in promoting efficiency.

The course is organized into 6 units. The percentages below are the College Board exam weights, so you can see which units carry the most multiple-choice points. Open each unit for its study guide, topic pages, key terms, and practice questions.
One core problem and the tools economists built to handle it.
AP Microeconomics Unit 2, Supply and Demand, is the unit where you learn the market model that drives the entire course.
AP Micro Unit 3 is where you stop looking at markets from the outside and step inside the firm.
AP Micro Unit 4, Imperfect Competition, is about what happens when firms have market power, meaning they can set price above marginal cost instead of taking the market price as given.
AP Micro Unit 5 flips the supply and demand model around.
AP Micro Unit 6, Market Failure and the Role of Government, answers the question that hangs over the whole course: what happens when markets get it wrong, and what can government do about it?
These trends come from real Fiveable practice data, so you can see what students are reviewing, which topics need extra attention, and how written practice can improve over time.

Skim the 6 unit pages, then choose the units that need the most review. Use topic guides for the concepts that feel fuzzy instead of rereading the whole course.
After each unit, answer practice questions and write free responses when they are part of the subject. Keep a short list of missed skills and revisit those guides before the next set.

AP Micro is one of the more manageable AP courses, but it asks for real effort. Across 6 units you read and interpret graphs, apply marginal analysis, and reason through trade-offs instead of memorizing facts. The graphs trip people up at first since supply and demand, cost curves, and market structure diagrams look alike. Once the logic clicks, the same reasoning carries across units, and steady practice makes it very doable.
Start by anchoring to the 6 units and the graphs in each one. Read the Unit 1 and Unit 2 guides first, since scarcity, marginal analysis, and supply and demand support everything later. After each unit, redraw the key graphs from memory and explain what every curve means. Then test yourself with practice questions and short FRQ practice so you build the writing and graphing skills the exam rewards.
On the multiple-choice section, Unit 3 (Production, Cost, and the Perfect Competition Model) carries 22 to 25 percent and Unit 2 (Supply and Demand) carries 20 to 25 percent, making them the heaviest. Unit 4 (Imperfect Competition) follows at 15 to 22 percent. Spend extra time on the cost curves, perfect competition, and monopoly graphs in these units, since the same diagrams appear throughout the free-response section too.
The free-response section has 3 questions and counts for 33.35 percent of your score. Question 1 is the long FRQ worth 10 points, and Questions 2 and 3 are short FRQs worth 5 points each. You get 60 minutes total, including a 10-minute reading period. Many points come from drawing accurately labeled graphs and showing the effects of changes, so practice both your graphing and your written explanations.
Microeconomics uses graphs to model decisions, so a diagram is the fastest way to show how prices, output, and surplus respond to change. Supply and demand shifts, cost curves, and monopoly profit diagrams each tell a story about marginal benefit and marginal cost. The free-response section directly rewards drawing accurately labeled graphs and demonstrating effects, so understanding what each curve represents matters more than memorizing shapes.
