AP Microeconomics

How markets and firms decide

AP Microeconomics is about choices made under scarcity: what a buyer is willing to pay, what a firm should produce, and what happens to both when a government steps in. In this course the graph does most of the explaining, so the practice sets draw it in every worked solution and the lab lets you move a policy and watch the areas change.

Labs

The PPC lab has you label a production possibilities curve, move it when resources or technology change, and place points inside, on and outside it. The market policy lab draws supply and demand, then adds a per-unit tax, a price ceiling or a price floor, and shades consumer surplus, producer surplus, tax revenue and deadweight loss as you move it.

The exam

The exam is hybrid digital: you answer the multiple-choice questions in the Bluebook app and handwrite the free-response answers in a paper booklet. A four-function calculator is enough for every calculation here.
