Exam requirements and worked examples

What the argument essay asks for

The six course countries are China, Iran, Mexico, Nigeria, Russia and the United Kingdom. The other free-response tasks cover concept application, quantitative analysis and comparative analysis. In the essay, read the permitted concepts and evidence instructions carefully. The argument needs a defensible claim, specific course-country evidence and reasoning connecting the evidence to the claim. College Board’s published scoring guidelines also illustrate how to describe and respond to an alternate perspective.

A thesis such as political institutions matter in many countries gives the reader little to test. Choose an outcome and a mechanism. For example, a parliamentary confidence convention can give a legislature leverage over the survival of an executive. Then identify the circumstances in which the leverage is likely to be strongest.

Official exam and example sources

Worked comparison of the United Kingdom and Mexico

Original practice question. To what extent do institutional rules explain how directly legislatures can threaten the tenure of a national executive? In the United Kingdom, the government must command the confidence of the House of Commons. In Mexico, Article 83 sets a six-year presidential term and bars return to the presidency. These features illustrate different institutional links between the legislature and executive survival.

A reasoned comparison explains the mechanism. Ordinary confidence can make continued parliamentary support a condition of remaining in office. A fixed term creates a different starting point for executive tenure. Then qualify the argument. Party cohesion and a large governing majority can reduce the immediate threat in a parliamentary system. A fixed presidential term still leaves room for oversight through mechanisms other than a routine confidence vote.

Fencing Method for an institutional word

Start with confidence in a simple sentence. The government needs the House’s confidence. Add detail by naming the House of Commons and the consequence for executive survival. Tighten the tone by saying can threaten where the political conditions vary. Add logic by tracing how a divided governing party could change the result of a vote. Transfer the move by comparing the source and duration of an executive mandate in a second course country.

Repeat with accountability. State who answers to whom, what action is being examined and what consequence is possible. A chamber can demand information, an election can remove a governing party, and a court can review legal authority. Naming the mechanism helps you explain which kind of accountability your evidence supports.

Build evidence cards that work across prompts

Put one institution, one rule and one consequence on each card. Add the course country, a reliable source and a date where relevant. On the reverse, put a limit. A constitutional rule may describe the available procedure, while voting patterns or party organization help you explain how often it affects outcomes.

Practise moving the same case between prompts. A confidence rule may illustrate executive selection, executive survival or legislative leverage. Adjust the explanatory sentence each time. If the link to a claim about turnout, public legitimacy or regime change is weak, select a different example. A familiar country is useful when the fact fits the specific political process you need.

Frequently asked questions

How many countries should I use? Follow the prompt and the applicable scoring guidelines, including any instructions about permitted evidence. Can the alternate perspective share some of my evidence? It can. Explain how a rival interpretation uses that evidence and why your position still stands, needs a condition or should be narrowed. How do I compare cleanly? Apply the same question to both countries before stating the difference.

Practise a credible alternate perspective

Write the strongest version of a rival explanation for your UK and Mexico comparison. One argument is that party organization matters more than institutional design because a united legislative majority can protect an executive from challenges. Explain why that argument has force. A threat can exist on paper while the votes to carry it out remain scarce. Then decide whether the example changes the claim about institutional rules or changes how broadly you can apply it.

A defensible reply can grant that parties shape the likelihood of a challenge while maintaining that rules shape the available route. This answers the objection because it separates frequency from procedure. Test the reply by rewriting your opening claim in one sentence. If you are now arguing about procedure, keep that term or its plain equivalent visible in your conclusion.

Separate political structure from political practice

For each course country, collect one rule and one example of its practical use. An institution’s legal authority can establish what action is possible. Evidence of party voting, bargaining or public response helps explain when it is used and with what consequences. If a prompt asks which institutional check has the greatest effect, you will need to say what counts as an effect and which kind of evidence shows it.

Apply this distinction to the word legitimacy. A government can have a legal mandate, but a claim about whether people see its rule as rightful requires evidence of public attitudes or behaviour. If you have participation data, explain what they show and what else might account for them. Several plausible explanations can coexist until more specific evidence distinguishes them.

Keep the quantitative task separate from the essay

In a data question, start by identifying the units, time range and direction of change. Then answer the required political connection. If a chart shows a turnout percentage, label it as a percentage and distinguish percentage-point change from percentage change. A rise from 40 percent to 50 percent is 10 percentage points. Use the scale of the chart when you make the comparison.

For a practice essay, turn the same data into evidence by adding a mechanism you can defend with a course example. If you lack evidence for the mechanism, qualify the claim. Review all four free-response formats together once you have practised them separately. That helps you allocate attention across the section and choose the kind of reasoning each prompt needs.
