AP Microeconomics
What the AP Microeconomics exam covers, how it's scored, the six units it's built on, and how to practice your way to a 5.
AP Microeconomics is a college-level introductory course and exam about how individuals and firms make decisions in markets — covering six units, from basic economic concepts to market failure and the role of government. The exam runs 2 hours and 10 minutes: a 60-question multiple-choice section (70 minutes) and a 3-question free-response section (60 minutes, one long question plus two short), scored from 1 to 5. It's taken in May, and many colleges grant credit for a 3 or higher — confirm your target college's policy.
Two sections, six units
The multiple-choice section carries two-thirds of the score and the free-response one-third, with questions drawn from the six units of the course.
60 questions, 70 minutes.
Discrete questions covering concepts, models and quantitative reasoning about markets, firms and prices — worth two-thirds of your score. Many ask you to predict how a change affects quantity, price, profit or efficiency.
3 questions, 60 minutes.
One long free-response and two short ones, with a 10-minute reading period. They reward drawing and analyzing graphs correctly — supply and demand, cost curves, the four market structures, factor markets — and explaining the reasoning. This is one-third of your score.
One 1–5 score.
The two sections combine into a single 1–5. A 3 is "qualified"; a 4 or 5 is strong. Score distributions are approximate and vary by year — confirm them on College Board, and check each college's credit policy.
Practice it, unit by unit.
Reading about economics isn't the same as answering AP-style questions and learning from every miss. Start free and practice by unit.

- Unit 6 — Market Failure and the Role of Government
How to study for AP Microeconomics
- Master each market structure — practice drawing and comparing them until it's automatic.
- Drill the free-response; on graphing questions, label axes and curves and show every step.
- Get the cost curves down cold — ATC, AVC, MC, MR — and how they interact.
- Keep your definitions precise — elasticity, marginal analysis, efficiency — they anchor the models.
- Review every miss until the concept, not just the answer, is clear; sit timed sets to build pace.
What makes AP Microeconomics different
Microeconomics studies choices inside markets and firms. The exam asks how incentives, costs, elasticity and market structure change decisions at a smaller scale.
| Area | What matters | Practice move |
|---|---|---|
| Core models | Individual markets | Practice supply and demand, elasticity, consumer choice, cost curves and market failures. |
| Firms | Market structure | Separate perfect competition, monopoly, monopolistic competition and oligopoly before drawing the graph. |
| Efficiency | Surplus and deadweight loss | Connect taxes, subsidies, price controls, externalities and public goods to welfare changes. |
| FRQ work | Label precisely | Mark profit, loss, quantity, price, marginal cost and marginal revenue so the grader can follow the decision. |
