AP Microeconomics FRQ: how to answer the free response.
The AP Microeconomics FRQ section is a third of your exam score, and it lives and dies on graphs: correctly labeled diagrams, precise economic reasoning, and shown calculations. Three questions carry 20 points between them — 10 on the long one, 5 on each short one — and this guide is part of our AP FRQ series.

What the AP Microeconomics free response looks like
Section II gives you three free-response questions in 60 minutes, worth about 33% of your score. It opens with a 10-minute reading period, leaving roughly 50 minutes of writing. The first is a long question worth 10 points; the other two are short questions worth 5 points each, so the section is 20 points in total. A four-function calculator is allowed.
The format is hybrid digital: you answer the multiple choice and read the free-response questions in the Bluebook app on a device, then handwrite your answers in a paper booklet that is collected and scored. Bring a pencil or a pen with black or dark blue ink, and expect to work between a screen and paper rather than annotating the question sheet.
The questions are applied: you will define terms, identify values, indicate directions of change, run small calculations, and above all draw graphs. College Board suggests spending about half your writing time on the long question and dividing the rest equally between the two short ones, which works out at roughly 25 minutes and then 12 to 13 minutes each.
Graphs win or lose the points
Nearly every AP Microeconomics free-response question expects a diagram, and College Board’s own instructions are blunt about what counts: a correctly labeled graph must have all axes and curves clearly labeled and must show directional changes. On a supply and demand diagram that means naming the axes Price and Quantity, naming every curve, and marking the shift and the new equilibrium with arrows or clear points. A right idea drawn with an unlabeled axis or a missing shift often earns nothing.
The core diagrams to own cold are supply and demand, including price ceilings, price floors and per-unit taxes and subsidies; the perfectly competitive firm and market drawn side by side, with marginal cost cutting marginal revenue at the profit-maximising quantity and the profit or loss area shaded; the monopolist with marginal revenue below demand; externalities, where the deadweight loss triangle is often the point; and the factor market. Consumer and producer surplus, price discrimination and simple game theory payoff matrices turn up regularly too. Draw them from a blank page until the labels are automatic.
A worked example, answered the way a grader reads it
Describing the rules only gets you so far. Here is an original prompt written in the exam’s style, worked through in the order the points are awarded. It is not a released question; for those, go to College Board directly.
Assume the market for bicycles is perfectly competitive and in equilibrium. A city opens a large network of protected bike lanes. Draw a correctly labeled graph of the bicycle market showing the effect on equilibrium price and quantity, and explain the direction of each change.
- Label the axes first. Price on the vertical axis, Quantity on the horizontal. Do this before you draw anything, because it is the cheapest point on the page and the easiest one to forget under time pressure.
- Draw and name both curves. Supply sloping up, demand sloping down, labelled S and D. Mark the starting equilibrium and label the price and quantity there.
- Make the shift, and say which curve moved. Protected lanes raise the benefit of owning a bicycle, so demand increases. Draw the new curve to the right, label it D1, and put an arrow between the two so the direction is unmistakable.
- Mark the new equilibrium. Label the new point and the new price and quantity. This is a separate point from drawing the shift, and it is routinely missed.
- Explain in economic terms. Demand increases because the lanes raise the benefit of owning a bicycle, so at every price consumers want more; the rightward shift raises both equilibrium price and quantity. Not “it goes up”.
How the AP Microeconomics FRQ is scored
Each question is scored point by point against a rubric, and the 20 points are spread across parts: a correct graph element, a correct numerical answer, and a correct explanation each earn credit. Partial credit is generous, so a slip on one part rarely sinks the whole question. When a prompt says “calculate”, you must show how you reached the number, not just state it.
Watch the task verb, because the rubric rewards the one that was asked. “Identify” wants a value or a name and nothing more; “explain” wants the reasoning; “indicate” wants a direction. Answering the wrong verb loses the point even when the economics is right. Answer every part, even briefly, and label as you go, because a labeled curve or a stated direction of change is often a free point.
Where students lose the most points
How to practice the AP Microeconomics FRQ
Work in this order. First, draw the core graphs from memory until labeling them is automatic. Second, drill one unit at a time with the Progress Check walkthroughs, and use the full AP Microeconomics review guide to connect the FRQ work to the rest of the exam. Third, and for most of your remaining time, write: work official past free-response questions under a timer and grade yourself against the published scoring guidelines, so you learn where the points live.
If you also sit AP Macro, do both together — the graphs differ but the marking does not, and our AP Macroeconomics FRQ guide follows the same method. When you want to see what a raw score becomes, run it through the AP Micro calculator.
Frequently asked questions
Quick answers, checked against College Board.
Is the AP Microeconomics FRQ handwritten or typed?
Handwritten. The exam is hybrid digital: you read the free-response questions in the Bluebook app on a device and write your answers, graphs included, in a paper booklet that is collected for scoring. Bring a pencil or a pen with black or dark blue ink.
Is a calculator allowed on the AP Microeconomics FRQ?
Yes, a four-function calculator is permitted on both the free-response and multiple-choice sections.
What if I cannot remember the right graph?
Draw what you can and label it properly, then answer the written parts in economic terms. Points are awarded per element, so a correctly labeled axis, a named curve or a stated direction of change still scores even when the rest of the diagram is wrong or missing.
Does "identify" mean the same as "explain"?
No, and the difference costs points. Identify asks for a value or a name only. Explain asks for the reasoning behind it. Indicate asks for a direction. Answering a different verb from the one in the prompt loses the point even when the economics is correct.
How is the AP Microeconomics FRQ different from AP Macroeconomics?
The structure is the same and the marking works the same way: three questions, one long and two short, scored point by point with graphs carrying much of the credit. The diagrams differ, which is why practising both together works well if you sit both exams.
Do I lose points for an untidy graph?
Not for neatness itself, but a grader has to be able to read what you meant. An ambiguous curve, an unlabeled axis or a shift that could be read either way will cost the point, so clarity is worth more than presentation.
