Everything below is free to work through and is organised against the same units as the official course framework, so you can go straight to the unit you are weakest in.

How the country actually scores

Approximate national results on AP Comparative Government & Politics from recent score reports. Use these as context, not as a prediction — the exact curve is set fresh each year.

Read that honestly: a 5 on Comp Gov is a minority outcome, earned by roughly one student in 4. It is not out of reach — but it is not the default outcome of finishing the class either, which is why the review phase below matters more than the coursework.

What a 5 in Comp Gov takes

The specific habits that separate a 5 from a 3 on this exam, drawn from the scoring patterns for Comp Gov.

• Always be prepared to compare at least two countries. The course is 'Comparative' Government, so FRQs will ask you to identify a concept and explain how it looks different in two specific core countries.
• Use the precise vocabulary. Don't say 'rules'; say 'regime.' Don't say 'country'; say 'state.' Demonstrating mastery of political science terminology earns points.
• Understand that legitimacy (the right to rule) can come from multiple sources: rational-legal (constitutions, elections), traditional (monarchy), or charismatic (a revolutionary leader).
• Be aware of current events up to the year before the exam, particularly regarding leadership changes, major protests, or shifts in electoral laws in the six core countries.
• Every free-response point in this course is earned with a country-specific noun. Replace "the legislature can check the executive" with "the House of Commons can remove the prime minister through a vote of no confidence." Build a one-page fact sheet per country listing the legislature name and seat count, the electoral formula, the executive’s term, and one signature policy or event.
• Learn the six countries as three matched pairs so comparisons come pre-assembled: UK versus Russia (parliamentary democracy versus hybrid semi-presidentialism), China versus Iran (single-party performance legitimacy versus theocratic legitimacy), Mexico versus Nigeria (federal presidential systems that democratized recently and depend on resource revenue).
• Master the difference between devolution and federalism, because it separates the UK and China from Russia, Mexico, and Nigeria. Devolved or provincial power is delegated and revocable by the center; federal power is constitutionally guaranteed. Exam distractors routinely call the UK federal.
• Institutional numbers are cheap points: Commons 650, Duma 450 (225 plus 225), NPC about 3,000, Mexican Chamber 500 (300 plus 200), Nigerian Senate 109 and House 360, Iranian Majlis 290 and Guardian Council 12. Drill them until they are automatic, then use them as the specificity that lifts a vague answer to full credit.
• On the Argument Essay, choose the thesis you can support with named institutions from two countries, not the thesis you find most persuasive. Write the claim, then immediately list the two country facts and the mechanism linking them, and reserve your last paragraph for a genuine counterargument you concede in part before rebutting.

The 5 units of AP Comparative Government & Politics

Unit names and exam weights follow the published course framework. Weights are the share of the multiple-choice section each unit is worth, so they tell you exactly where to spend time: Unit 2 (Political Institutions), Unit 1 (Political Systems, Regimes & Governments), Unit 5 (Political & Economic Changes) are worth roughly 56–84% between them.

On exam day

The exam-specific warnings our Comp Gov lessons flag as you go.

• Keep the four core terms sharp: **state** (sovereign territory), **nation** (shared identity), **regime** (enduring rules/institutions), **government** (current officeholders). AP prompts frequently test whether you can tell a change of *government* (an election) from a change of *regime* (a revolution).
• Do not equate "holds elections" with "democracy." Russia and Iran hold elections but are hybrid/authoritarian because competition is managed. On the exam, judge a regime by whether power is genuinely **contested and constrained**, not just by whether ballots are cast.
• When a prompt describes a democracy that "cannot deliver," reach for **state capacity**, not regime type. AP loves scenarios where a country is democratic in form but weak in practice (Nigeria) versus authoritarian but effective (China) — separate the two dimensions explicitly.
• For every executive question, ask two things: (1) Is the executive accountable to the legislature (parliamentary) or elected separately for a fixed term (presidential)? (2) Are the head-of-state and head-of-government roles combined or split? These two axes classify all six countries.
• Watch for bicameralism tracking federalism: federal states (**Russia, Mexico, Nigeria**) tend to have a second chamber representing regions, while the unitary authoritarian systems (**China, Iran**) are unicameral. The UK is unitary but bicameral — a useful exception to remember.
• The UK’s historic principle of **parliamentary sovereignty** means Parliament’s statutes were traditionally supreme and not subject to being struck down by courts — a sharp contrast with strong judicial review. Note the 2009 UK Supreme Court can review *government actions* but this legislative-supremacy tradition still shapes the system.
• On cleavage questions, state both the *type* and the *effect*: cross-cutting → moderates conflict; coinciding/reinforcing → intensifies conflict. Then anchor it to a country (Nigeria for reinforcing ethnic-religious-regional divides) for full credit.
• Link civil society to democratization: a strong, independent civil society supports democratic transition and consolidation, which is exactly why authoritarian regimes (China, Russia, Iran) work to co-opt, corporatize, or repress it. State that causal link explicitly in essays.
• Rank media freedom across the six: **UK** (free) → **Mexico/Nigeria** (free but journalists endangered) → **Russia/Iran** (state-controlled, censored) → **China** (most controlled, Great Firewall). Free-response prompts often ask you to compare two countries’ media environments directly.
• Memorize the pairing: **FPTP → two parties** (UK), **PR → many parties + coalitions**, **mixed → in between** (Mexico, Russia). When a prompt changes the electoral rules, predict the party-system effect through Duverger’s law for full credit.
