How AP Micro FRQs Are Scored
AP Micro FRQs are NOT essays — they are structured, point-based questions. Each sub-part earns an independent point. This means:
- Earn or lose points part by part
- A wrong answer to Part A doesn't prevent you from earning Part B
- Graphs earn points by having correct labels and shapes — not beautiful drawings
- Written explanations earn points by using economic vocabulary and causal reasoning
Most missed points on AP Micro FRQs: Unlabeled graphs. A perfectly shaped graph with no axis labels, no curve labels, and no equilibrium point earns zero.
The Most Important Rule: Always Label Your Graphs
Every graph on AP Micro FRQ must have:
- Both axes labeled (Price on vertical, Quantity on horizontal — or as specified)
- All curves labeled (Supply, Demand, MR, MC, ATC, etc.)
- Equilibrium point labeled (P*, Q* or P₁, Q₁)
- Direction of shift shown (arrow on shifted curve, new labels like S₂, D₂)
Missing any of these costs points even if the graph is otherwise correct.
FRQ 1 — The Long Question (10 pts)
The long FRQ typically spans multiple concepts — it usually starts with a market analysis and then adds a complication (tax, subsidy, externality, market power).
Common Long FRQ Structure
(a) Draw and label a correctly functioning market (2 pts) Draw a supply-demand graph showing initial equilibrium P* and Q*.
(b) Show an effect on the graph (1–2 pts) If demand increases: shift D right, label new curve D₂, show new equilibrium P₂ and Q₂ (both higher).
(c) Identify a related economic concept (1 pt) "Consumer surplus increases because the area between the demand curve and price has grown."
(d) Analyze a policy (2–3 pts) If a per-unit tax is imposed: shift S left by the amount of the tax, show new equilibrium, identify who bears more of the burden based on elasticity.
Worked Example: Externality Question
Prompt: The market for cigarettes produces a negative externality. Using a correctly labeled graph, show the socially optimal output and explain the role of government.
Graph: Draw D and S intersecting at Q_market. Draw a second supply curve S_social (shifted left, representing social cost = private cost + external cost). Show Q_social < Q_market and label the deadweight loss triangle.
Written explanation: "The market overproduces at Q_market because producers only account for private costs. The social optimum Q_social is lower, where marginal social cost equals marginal social benefit. Government can correct this by imposing a per-unit tax equal to the marginal external cost, shifting supply left to S_social and restoring the efficient output."
FRQ 2 & 3 — Short Questions (6 pts each)
Short FRQs typically test one or two concepts in depth.
Common Short FRQ Topics
Perfectly competitive firm:
- Show profit-maximizing output (where P = MC, or MR = MC)
- Show economic profit/loss (compare P to ATC at Q*)
- Show shutdown condition (P < AVC)
- Show long-run equilibrium (P = ATC = minimum)
Monopoly:
- Show profit-maximizing output (where MR = MC, not where P = MC)
- Show deadweight loss triangle between competitive and monopoly output
- Compare price and output to perfect competition
Factor markets:
- Draw labor market with MRP (marginal revenue product) as demand
- Show wage determination
- Show monopsony (single employer paying below competitive wage)
Elasticity:
- Calculate price elasticity: %ΔQ / %ΔP
- Determine who bears tax burden (inelastic side bears more)
- Explain relationship between elasticity and total revenue
Worked Example: Monopoly Short FRQ
A monopolist faces a downward-sloping demand curve. Draw a correctly labeled graph showing profit-maximizing price and quantity. Shade the area of economic profit.
Graph must show:
- Downward-sloping Demand (D) curve
- Marginal Revenue (MR) curve — below and steeper than D
- Upward-sloping MC curve
- MR = MC intersection → drop down to horizontal axis → label Q_m
- From Q_m, go UP to D curve → label P_m
- ATC curve — draw through or below P_m at Q_m for profit
- Shade rectangle: (P_m - ATC) × Q_m = economic profit
Key point: P_m is read off the DEMAND curve at Q_m — not off MR or MC. Students who read price off MR lose the point.
How to Answer "Explain" Questions
AP Micro FRQs frequently ask you to "explain" or "using your graph, explain." Full credit requires:
- State what happens (direction of change)
- Explain why (the economic mechanism)
- Connect to the graph (reference specific curves or points)
❌ "Price increases because supply decreased."
✅ "When the supply curve shifts left, the new intersection of supply and demand occurs at a higher price level. This is because at the original price, quantity demanded now exceeds quantity supplied, creating a shortage that drives the price up to the new equilibrium P₂."
AP Micro Concepts Most Tested on FRQs
| Concept | What to Know |
|---|---|
| Supply and Demand | Shifts vs. movements, elasticity, surplus/shortage |
| Consumer/Producer Surplus | CS = area above P below D; PS = area below P above S |
| Externalities | Negative: overproduction, need Pigouvian tax; Positive: underproduction, need subsidy |
| Perfect Competition | P = MC = min ATC in LR; zero economic profit |
| Monopoly | MR < P; DWL triangle; higher P, lower Q than PC |
| Monopolistic Competition | LR: P = ATC but P > MC (excess capacity) |
| Factor Markets | MRP = demand for labor; MRP = W at optimum |
| Public Goods | Non-excludable, non-rival; free rider problem; government provision |
