Stopping the causal chain too early
On both MCQ and FRQ, students often identify the first effect of a policy and stop. If the question asks what happens to the exchange rate after a change in interest rates, you need to trace: interest rates rise, capital inflows increase, demand for domestic currency rises, currency appreciates. Each link matters.
Drawing graphs without labels
Unlabeled axes, unnamed curves, or missing equilibrium points cost points on every FRQ graph. Graders cannot award credit for a correct shift if they cannot confirm what the axes represent. Label everything, every time.
Confusing fiscal and monetary policy tools
Saying 'the government raises interest rates' or 'the Fed increases spending' are both wrong. Fiscal policy tools are government spending and taxes, controlled by Congress. Monetary policy tools are open market operations, the discount rate, and reserve requirements, controlled by the Fed.
Using vague explanation language on FRQs
Writing 'aggregate demand increases' without stating why or what happens next does not earn explanation points. FRQ rubrics require you to name the mechanism: what changed, why it caused the shift, and what the new equilibrium implies.
Misallocating time across FRQ parts
Spending 20 minutes on the long FRQ's first two parts and rushing through the remaining four is a common scoring loss. The long FRQ has roughly equal point value per part. Use the reading period to plan your time before you start writing.
