Study Guide

Unit-by-unit breakdown of what the course actually covers, in teaching order.

Political Systems, Regimes & Governments

Sovereignty, legitimacy (traditional, charismatic, rational-legal per Weber), and regime type classifications (democracy, authoritarianism, hybrid regimes) applied specifically to the UK, Russia, China, Mexico, Iran, and Nigeria as the six required case-study countries.

Political Institutions

Executive structures (UK's parliamentary PM vs. Russia/China/Iran's more centralized executives), legislative bodies and their real versus symbolic power (China's National People's Congress vs. UK's Parliament), and judicial institutions' varying degrees of independence across the six countries.

Political Culture & Participation

How historical and social context shapes political culture differently in each case-study country, voter turnout and participation patterns, and the role of media (state-controlled in China/Russia vs. relatively free in the UK) in shaping political engagement.

Party & Electoral Systems, Civil Society

Single-party systems (China) versus multi-party competitive systems (UK) versus dominant-party/hybrid systems (Russia, Iran, Mexico historically), electoral rules' effects on party systems (first-past-the-post vs. proportional representation), and civil society's varying room to operate across regime types.

Political & Economic Change

Democratization and authoritarian backsliding as opposite directional pressures seen across the six countries, economic liberalization's political effects (China's market reforms under continued one-party rule), and specific historical transition moments (Mexico's PRI dominance ending, post-Soviet Russia).

Sample Comparative Analysis Breakdowns

Concrete comparisons across the six required countries — this is the actual skill tested, not just recalling facts about each country in isolation.

Political Systems, Regimes & Governments

Comparative prompt: "Compare how legitimacy is established in the United Kingdom versus China."

A strong answer names the specific type: the UK relies heavily on rational-legal legitimacy (power flows from constitutional procedure and free elections), while China's CCP relies more on performance legitimacy (delivering economic growth and stability) combined with ideological legitimacy — not on competitive multi-party elections. Naming the specific legitimacy type, not just describing each country generally, is what the rubric checks for.

Political Institutions

Concept application: explain why the UK Prime Minister typically has an easier time passing legislation than the U.S. President.

In the UK's parliamentary system, the PM is the leader of the majority party (or coalition) in Parliament, so the executive and legislative majority are fused, minimizing gridlock. In the U.S. presidential system, separate elections for executive and legislature mean the President can face a Congress controlled by the opposing party (divided government), creating more structural gridlock.

Political Culture & Participation

Data analysis: voter turnout is 65% in the UK and 45% in Nigeria for comparable elections.

A strong response doesn't stop at the numbers — it connects the gap to a specific factor, such as differing levels of institutional trust, ease of voter registration, or the competitiveness of the specific race, rather than a vague claim that one country's citizens simply "care more."

Party & Electoral Systems, Civil Society

Concept application: explain how first-past-the-post (UK) versus a more centralized single-party system (China) shapes each country's party landscape.

First-past-the-post tends to produce and sustain a two-party-dominant system (Duverger's Law) since smaller parties struggle to win any seats without a plurality anywhere. China's single-party system doesn't compete for seats at all in the Western sense — the CCP controls candidate selection, making the entire concept of party competition inapplicable in the same way.

Political & Economic Change

Argument essay: "Does economic liberalization necessarily lead to political democratization?" Use China as a case.

A strong, well-supported answer takes a position (no) and cites China specifically: market reforms since the 1980s have produced enormous economic liberalization without corresponding political liberalization — the CCP has maintained one-party control throughout, directly contradicting the assumption that the two must move together.

Study Tips

  • Know the six course countries (China, Iran, Mexico, Nigeria, Russia, UK) well enough to compare two of them directly on any concept.
  • Practice reading tables/graphs quickly — the quantitative-analysis FRQ rewards precise data description before interpretation.
  • Always ground an answer in one or more of the six required countries by name (UK, Russia, China, Mexico, Iran, Nigeria) with a specific, accurate fact — a general claim without a named country example won't earn credit.
  • When comparing two countries, state the actual comparison explicitly ("unlike the UK's X, China's Y...") rather than describing each country in a separate paragraph and leaving the comparison implicit.
  • For data-analysis questions, connect the numbers to a specific causal factor rather than a vague generalization about a country's culture or citizens.

Common Mistakes, Ranked by Point Loss

The errors that cost the most points across the whole exam, not just one unit.

  • 1. Making a general claim about "government" or "democracy" without anchoring it to a specific one of the six required countries.
  • 2. Describing two countries in separate, parallel paragraphs without ever stating the explicit comparison between them.
  • 3. Confusing a country's formal institutions (what the constitution says) with how power actually operates in practice — especially relevant for Russia, China, and Iran.
  • 4. Assuming economic liberalization and political democratization always move together, when several required countries (China especially) directly contradict that assumption.
  • 5. Treating single-party systems (China) using the same competitive-party-system vocabulary that applies to the UK or Mexico, when the concepts don't map cleanly.
