What examiners penalize here
- 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.
Practice Comp Gov
Our practice bank is drawn from across the whole course rather than filtered to one unit, which is closer to how the exam asks anyway — it will not tell you which unit a question is testing.
