22 multiple-choice questions in College Board exam style. Each has four choices and a full explanation of why each option is right or wrong.
Read the question carefully before looking at the choices. Many AP Micro questions have answers that look almost identical; small wording differences matter.
Eliminate before guessing. AP Micro distractors often confuse absolute advantage with comparative advantage, or demand shifts with movements along the curve. Cross out anything that mixes these up.
Sketch the graph if a question describes one. Many Unit 1 questions are easier to answer once you draw the PPC, demand curve, or supply curve they're describing.
Read the explanations even when you got it right. Each one teaches a small fact that often returns in a different form on the exam.
