AP Microeconomics review: exam format, the 6 units, and how to study

What’s on the AP Microeconomics exam

The AP Microeconomics exam splits into two sections. Section I gives you 70 minutes for 60 multiple-choice questions, drawn from all 6 units and worth 66.65%. Section II gives you 60 minutes for 3 free-response questions worth 33.35%, and it opens with a 10-minute reading period. Those three questions carry 20 raw points between them: one long question worth 10, and two short questions worth 5 each. Our AP Microeconomics FRQ guide breaks all three down part by part.

The calculator rule is narrower than most guides say. Both sections permit a four-function calculator, and Bluebook builds one in. What the policy then rules out is any handheld that can store things, and it names scientific and graphing calculators as the examples. A scientific calculator you bring from home will be turned away at the desk, which is a better thing to find out now than on exam morning.

Delivery is hybrid. You answer the multiple choice in the Bluebook app and read the free-response prompts there as well, then handwrite your answers in paper booklets that are collected for scoring. AP Microeconomics is one of several subjects run this way; if the format is new to you, we have digital AP exams explained across the catalog.

The 6 units of AP Microeconomics

College Board organizes the course into 6 units and publishes a weighting for each one on the multiple-choice section. That qualifier matters: the free-response section is not divided by unit at all, so these percentages tell you how the 60 multiple-choice questions are distributed and nothing about the 3 free-response questions. Units 2 and 3 are the two largest, and together they can account for up to half of the multiple choice.

The graphs the AP Microeconomics exam requires

Graphing is the one skill category that never appears on the multiple choice. College Board divides the AP Economics skills into four categories and states that Skill Category 4, Graphing and Visuals, cannot be assessed by a multiple-choice question, because it requires you to draw. Graphs themselves still turn up on the multiple choice; what you are never asked to do there is produce one. On the free-response section the same skill is the heaviest of the four task types: creating graphs or visual representations accounts for 30–50% of the total free-response points. Explaining is 25–35%, numerical analysis 15–30%, and making assertions 10–20%.

The useful part is that College Board publishes the actual list, in an appendix most guides never open. It names every model that can appear, and it splits them in two.

The 16 you have to be able to draw

These are the models College Board says you must be able to draw yourself on the free-response section, as well as read when one is given to you.

• The production possibilities curve model
• Utility, total and marginal
• Demand and supply
• Demand and supply for the domestic market under international trade
• The production function
• Per-unit costs in the short run (AFC, AVC, ATC, MC)
• Costs in the long run (LRATC)
• Perfect competition
• A perfectly competitive market and a firm in that market, side by side
• Monopoly and monopolistic competition
• Natural monopoly
• The game theory matrix
• Factor markets
• A firm in a perfectly competitive factor market (MFC, MRPL)
• Monopsony
• Externalities in perfectly competitive markets, in all four cases

The 3 you only have to read

These are listed separately, under a heading stating that you will not be expected to draw them. You can still be asked about them in either section when the graph is supplied.

• Total costs in the short run (TFC, TVC, TC)
• Externalities in imperfectly competitive markets
• The Lorenz curve

What College Board puts out of scope

Five exclusions sit in the framework, and every one of them is something you can cross off.

• Indifference curves, though setting marginal utility per dollar equal across goods is still in scope
• Graphing quotas, though understanding how a quota affects quantity is in scope
• Dominant strategies and Nash equilibria beyond two players or two actions each, mixed strategies, and extensive-form games
• A graph of inefficiency and policy under collusion
• Drawing a Lorenz curve, and Gini coefficient calculations

A labeled graph is not the same as an accurately labeled one. College Board describes what it wants: points, curves and shaded areas labeled and correctly placed, and for a change, labeled shifts in curves, the new price and quantity, arrows showing the direction of change, and shading where area is the point.

How AP Microeconomics is scored

Your multiple-choice and free-response points are weighted and combined into a single composite score, which College Board converts to a 1–5 each year. It publishes neither the conversion table nor the cut scores, so treat every raw-to-5 chart you find, including ours, as an estimate rather than a rule.

The 2026 pass rate was 68%, split 19% fives, 26% fours and 23% threes. College Board has published 2026 as percentages only so far, with the cohort size and mean still blank. For a complete year you want 2025: 117,548 test takers, a 68.17% pass rate, mean 3.24.

Read that against the rest of the catalog rather than on its own. Across the 40 AP exams scored in 2026 the average pass rate was 73%, and AP Microeconomics ranked 29th of 40. Its mean score sits at the middle of that field; its pass rate sits in the bottom third of it. This is not one of the softer AP exams.

How to study for AP Microeconomics

Two pieces of College Board’s own teacher guidance should shape the order you work in, and both cut against studying by weighting alone.

The units it flags as trouble are the two smallest. College Board singles out factor markets as one of the places students struggle most on the exam, and says the Unit 6 material on externalities and government intervention sits behind some of the questions students get wrong most often. In both cases it gives the same reason: those units sit at the end of the course and carry the smallest share of the multiple choice, so classes rush them. Units 5 and 6 are 10–13% and 8–13%. They are also where points quietly disappear.

Make the graphs automatic, using the list above. Draw each of the 16 models from a blank page with every axis, curve and point labeled, then practice showing a change on it rather than only setting it up. College Board notes that students lose points for exactly these two things: not labeling axes and curves properly, and not demonstrating the effect of a change properly. Knowing the 3 you never have to draw, and the 5 exclusions, is time you get back.

Then work against real questions. Take past free-response questions and score them against the published rubric instead of reading the answer, and go unit by unit with the AP Microeconomics Progress Check answers. Where the numbers are the problem, slow down on the two calculations College Board singles out: elasticity as a percentage change rather than a raw change, and the area of the correct triangle for surplus and deadweight loss.

When is the AP Microeconomics exam, and how long is it

AP Microeconomics is given once a year during College Board’s May testing window. The 2027 exam is on Tuesday, May 4, 2027, in Session 2. That session starts at 12 p.m. local time in the lower 48 states, Hawaii and Washington, D.C. (11 a.m. in Alaska), and a school can begin it up to an hour later, so confirm the exact time with your AP coordinator. The exam itself takes 2 hours 10 minutes in total, of which 70 minutes go to the multiple choice and 60 to the free response, the second figure including its 10-minute reading period.
