AP Microeconomics Study Guide
AP Micro shares Macro's graph-heavy format but applies it to firm and market behavior instead of the national economy — supply/demand, cost curves, and market structure graphs (perfect competition, monopoly) are the backbone of nearly every FRQ.

Cost curves and firm behavior under perfect competition.
Unit 4: Imperfect Competition

Common Mistakes to Avoid
- Drawing cost curves without the correct relationship between marginal cost and average cost curves (MC must cross AC/AVC at their minimum) — a frequently checked graph detail.
- Confusing which market structure a scenario describes, especially between monopolistic competition and oligopoly.
- Forgetting that a profit-maximizing firm produces where MR = MC, not where price is highest or cost is lowest.
- Not explaining the reasoning behind a graph — like Macro, labeling correctly is necessary but not sufficient; the written justification is scored separately.
