Everything happens in Bluebook

You answer every question, including the written responses, in College Board's Bluebook app. Practice typing timed answers before May.

The six core countries

Every question draws on China, Iran, Mexico, Nigeria, Russia and the UK. They range from democracies to authoritarian regimes, so you can compare institutions, elections and policies across systems.

Section I

The multiple-choice section

55 questions in 60 minutes gives you just over 1 minute per question. Knowing country facts well is what makes this pace possible. Wrong answers lose no points.

Strategies that work

  • Know the vocabulary precisely: legitimacy, sovereignty, authority, power, state, nation, regime.
  • Classify each country as democratic, hybrid or authoritarian, and be ready to explain why.
  • Read charts as evidence for a claim. Look at the axes and the time period first.
  • Compare systems: presidential, parliamentary and semi-presidential; single-member districts and proportional representation.
  • Eliminate answers about the wrong country. Many wrong choices are true of a different country.
  • Flag and move on after 90 seconds.
What the course covers

The 5 units, in plain English

Unit 118–27%

Political Systems, Regimes & Governments

What kind of state each country is.

Be ready to: Compare democratic and authoritarian regimes; explain sources of legitimacy and stability; describe federal and unitary systems; measure democracy with indicators.

Unit 222–33%

Political Institutions

Executives, legislatures and courts.

Be ready to: Compare presidential, parliamentary and semi-presidential systems; explain term limits and removal; describe legislative independence; compare judicial independence and review.

Unit 311–18%

Political Culture & Participation

How citizens relate to government.

Be ready to: Explain political socialization and ideology; compare civil rights and liberties; analyze social movements and how governments respond to cleavages.

Unit 413–18%

Party & Electoral Systems & Citizen Organizations

Elections, parties and interest groups.

Be ready to: Compare single-member district and proportional representation systems; explain party systems; describe pluralist and corporatist interest groups.

Unit 516–24%

Political & Economic Changes & Development

How globalization and policy reshape states.

Be ready to: Explain economic liberalization, privatization and globalization; analyze responses to economic change, social policy and environmental challenges.

Political institutions is the biggest unit, so learn how each country organizes its executive, legislature and courts first. A comparison grid helps: rows for each concept (executive, legislature, elections, parties, civil society), columns for the six countries.

Section II

The 4 free-response questions

90 minutes, 4 questions: Q1 is worth 11% of your score, Q2 and Q3 12.5% each and Q4 14%. The four question types are the same every year.

Q1 · Concept

Conceptual analysis

Define or describe a political concept, then explain it and apply it to a situation.

Definitions must be precise; the rest of the answer builds on them.

Q2 · Data

Quantitative analysis

Describe data from a chart or table, identify a pattern, and draw a conclusion linked to a political concept.

Use exact numbers and compare at least two data points.

Q3 · Compare

Comparative analysis

Compare how two of the six countries handle a concept, explaining a similarity or difference and its effect.

Give a specific fact for each country, not a general claim.

Q4 · Argument

Argument essay

Build an argument with a claim, two pieces of evidence from course countries, reasoning, and a response to an opposing view.

Choose the side you can support with the most specific country evidence.

Time plan: About 10 minutes for Q1, 20 each for Q2 and Q3, and 40 for Q4. In comparisons, write "whereas" sentences: "The UK has a fused executive, whereas Mexico…".

Habits that earn points

  1. Answer each lettered part separately and in order.
  2. Define concepts precisely before applying them.
  3. Use a specific fact for every country you name.
  4. Quote numbers from charts and compare them.
  5. Stuck? Define the concept; it can still earn a point.
Learn from others

10 traps that cost points

  1. State vs nation

    A state is a political unit with sovereignty; a nation is a group sharing identity. They don't always match.

  2. Legitimacy vs power

    Legitimacy is acceptance of the right to rule; a regime can have power without legitimacy.

  3. Wrong executive type

    UK: parliamentary. Mexico and Nigeria: presidential. Russia: semi-presidential. Know each one.

  4. Iran's two leaders

    The Supreme Leader outranks the elected president and controls key institutions.

  5. China's elections

    China has local elections and a legislature, but the Communist Party controls candidates and decisions.

  6. Federal vs unitary

    Mexico, Nigeria and Russia are federal; the UK, China and Iran are unitary (the UK with devolution).

  7. Vague comparisons

    "Both countries have elections" isn't a comparison. Explain a specific similarity or difference and why it matters.

  8. Ignoring the chart

    In Q2, use the data shown. General knowledge alone won't earn the points.

  9. Missing the opposing view

    The argument essay needs a counterargument and a rebuttal.

  10. Out-of-date facts

    Leaders and policies change. Focus on how institutions work, not who is in office.

3 practice questions

Original questions written by ACT SAT GO in the style of the exam. The free PDF has 10, with full explanations.

  1. Unit 1 · Legitimacy

    A government that bases its legitimacy mainly on economic growth and improving living standards is relying on:

    • A rational-legal legitimacy through elections
    • B traditional legitimacy
    • C performance legitimacy
    • D charismatic legitimacy
    Show answer

    Answer: C. Performance legitimacy comes from delivering results, such as economic growth. The Chinese government relies heavily on it.

  2. Unit 4 · Electoral systems

    Compared with proportional representation, single-member district plurality systems tend to:

    • A produce more parties in the legislature
    • B favor two large parties and produce single-party majorities
    • C guarantee seats in exact proportion to votes
    • D require coalition governments
    Show answer

    Answer: B. Duverger's law: winner-take-all districts discourage small parties, tending to produce two-party systems and single-party majorities.

  3. Unit 2 · Judiciary

    Which country's highest court has the weakest power of judicial review over national legislation?

    • A United Kingdom
    • B Mexico
    • C Nigeria
    • D Russia (formally)
    Show answer

    Answer: A · United Kingdom. Because of parliamentary sovereignty, UK courts can't strike down acts of Parliament, though they can issue declarations of incompatibility.
