20 multiple-choice questions in College Board exam style. Each has four choices and a full explanation of why each option is right or wrong.
Treat currencies like any other good. The foreign exchange market follows the same supply-and-demand logic from Unit 1 — just apply it to a new "good."
Appreciation isn't automatically "good." It helps importers and consumers but hurts exporters — read the question carefully to see which side it's asking about.
Track the full chain for policy questions. Monetary/fiscal policy → interest rates → capital flows → currency demand → exchange rate → net exports. Many questions test one full chain at once.
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.
