AP Microeconomics 30% Sectional Test: Units 1 and 2
AP Microeconomics 30% sectional test covers Units 1 and 2 — PPC, comparative advantage, supply/demand graphs, elasticity, taxes, and price controls practice.
Checkpoint 1: Foundations of Economic Analysis
The 30% sectional test covers the first two units of AP Microeconomics — Basic Economic Concepts and Supply and Demand. This checkpoint confirms that you have built the analytical foundation necessary for everything that follows. A strong performance here means you are ready to move into firm-level cost analysis in Unit 3.
What This Sectional Tests
Unit 1 Content: PPC and Comparative Advantage
From Unit 1, the sectional tests your ability to read and interpret production possibilities curves, calculate opportunity costs from PPC diagrams or production tables, and determine comparative advantage for specialization and trade. Circular flow model questions may also appear, asking you to identify the direction of resource and money flows between households and firms.
Unit 2 Content: Full Supply and Demand Analysis
Unit 2 content forms the majority of this sectional. Questions test:
- Drawing and shifting supply and demand curves based on stated changes in determinants.
- Identifying the new equilibrium price and quantity after a shift.
- Calculating or interpreting price elasticity of demand and supply.
- Distinguishing elastic, inelastic, and unit-elastic demand scenarios.
- Calculating income elasticity (normal vs. inferior good) and cross-price elasticity (substitute vs. complement).
- Identifying consumer surplus, producer surplus, and total surplus areas on a diagram.
- Analyzing the effects of a per-unit tax — new equilibrium, tax burden distribution, deadweight loss.
- Showing the effects of price ceilings and price floors, including surplus and shortage.
Skills Reinforced at This Checkpoint
The 30% sectional reinforces the two most fundamental AP Microeconomics graph skills: drawing a correctly labeled supply/demand diagram and interpreting changes to market equilibrium. These skills appear in some form in virtually every AP Microeconomics FRQ, making this checkpoint a critical quality gate before advancing to more complex units.
Identifying Gaps Early
Students who struggle with elasticity calculations or cannot correctly shade a deadweight loss triangle at this stage will face compounding difficulty in later units. This sectional is designed to surface those gaps while there is still time to address them before the exam.
How to Prepare for the 30% Sectional
- Review PPC and comparative advantage problems from Unit 1.
- Practice drawing supply and demand diagrams from scratch without looking at reference materials.
- Work through at least five elasticity calculation problems.
- Draw the tax diagram — with supply shift, buyer price, seller price, and deadweight loss — until it is automatic.
