AP US Government · Lesson 48

What you should know without notes

A closed-notes final review: thirteen foundational documents, fourteen required cases, branch powers and checks, the four FRQ jobs, and current cases kept in context.

Closed-notes recall

In the final week, use closed-notes recall to identify what still needs review. Try to state each power, case, document, clause, threshold, or causal sequence from memory, then return only to the material you cannot reconstruct accurately. The review is organized by the information you need to recall on the exam rather than by chapter order.

Rebuild the five units from memory

Before checking any table below, try stating in one sentence each what Units 1 through 5 are about: the constitutional foundation and federalism, the three national institutions and their interactions, civil liberties and civil rights, political ideology and belief formation, and political participation. If any one sentence is hard to produce, that unit deserves a closer look before exam day, not just a page turn.

Table 42.1 Thirteen foundational documents, one claim each.
DocumentCore claim
Declaration of IndependenceLegitimate government rests on natural rights and the consent of the governed
Articles of ConfederationA weak national government dependent on state cooperation for money and enforcement
ConstitutionDivides and structures national power through enumerated powers, separated branches, and checks
Brutus No. 1A large national republic will weaken representation and let federal power expand at state expense
Federalist No. 10An extended republic dilutes factions across many competing interests
Federalist No. 39The Constitution is genuinely republican and mixes national and federal features
Federalist No. 51Separated institutions with competing incentives check one another
Federalist No. 70A single energetic executive supports accountability and decisive action
Federalist No. 78Judicial independence lets courts enforce constitutional limits without electoral pressure
Gettysburg AddressReasserts equality and popular sovereignty as founding principles during a national crisis
Letter from a Birmingham JailDefends disciplined nonviolent direct action against persistent, real injustice
Emancipation ProclamationDeclared enslaved people in rebellious areas free, a wartime measure, not the act that ended slavery nationwide
Core principles from Adam Smith's The Wealth of Nations (1776)Markets generally allocate resources well, though government still has defense, justice, and select public roles

Know the required cases by constitutional principle

Group the fourteen required cases by the constitutional question each one answers, rather than by the order this course covered them. Marbury and judicial review. McCulloch and Lopez together, defining the reach and the limit of implied national power. Engel and Yoder, the two religion clauses. Schenck and Brandenburg's later standard, and Tinker and New York Times Co. for speech and press. Gideon and McDonald for incorporation. Baker v. Carr and Shaw v. Reno for representation and Equal Protection. Brown for equal protection directly. Citizens United for campaign finance.

Table 42.2 Fourteen required cases, organized by the question each one answers.
CaseConstitutional question it answers
Marbury v. MadisonDo federal courts have the authority to review government action against the Constitution
McCulloch v. MarylandHow far does Congress's implied power reach
United States v. LopezWhere does that implied power stop
Engel v. VitaleCan government sponsor an official prayer
Wisconsin v. YoderWhen does a law burden religious exercise too heavily
Schenck v. United StatesHistorical wartime speech restriction standard
Tinker v. Des MoinesHow far does student political expression extend
New York Times Co. v. United StatesHow heavy is the burden to justify prior restraint
Gideon v. WainwrightDoes the right to appointed counsel apply to the states
McDonald v. ChicagoDoes the right to keep and bear arms apply to the states
Baker v. CarrCan federal courts hear a malapportionment claim
Shaw v. RenoWhen does race in district design violate Equal Protection
Brown v. Board of EducationDoes racial school segregation violate Equal Protection
Citizens United v. FECAre independent political expenditures protected speech

Reconstruct branch powers and checks

Without looking back, try to state one formal power specific to each branch and one check each branch faces. Congress can pass legislation and override a veto with two-thirds of both chambers; it faces judicial review of the statutes it passes. The president can veto legislation and command the armed forces; the president faces Senate confirmation of appointments and impeachment. Courts can declare government action unconstitutional; courts depend on other institutions for appointment, jurisdiction, and enforcement of their rulings.

Rebuild the four FRQ jobs without looking back

  • Concept Application: read the three lettered parts and obey each task verb. The sequence is not fixed as identify-explain-apply. Use the scenario and explain a political mechanism whenever asked how or why.
  • Quantitative Analysis: read the legend, variables, denominator, time period, and scale; identify or describe the requested pattern; draw only conclusions supported by the data; and connect the pattern to a course concept when asked. Be ready for tables, graphs, maps, and infographics.
  • SCOTUS Comparison: three lettered parts, four total points. Identify the shared constitutional basis when asked; use accurate required-case knowledge; explicitly compare the facts and holdings for full Part B credit; then connect the nonrequired case to the named political concept in Part C.
  • Argument Essay: one thesis point, up to three evidence points, one reasoning point, and one alternate-perspective point. For the top evidence score, use two specific relevant pieces and make at least one a foundational document listed in the prompt.

A closed-notes check

Core closed-notes retrieval is limited to required CED content: the required cases, required foundational documents, constitutional provisions, institutions, political processes, data skills, and the four FRQ scoring jobs. Answer each question in the practice set from memory before checking the response.

Current cases for context

These cases can help with current examples, but they are not part of the fourteen required-case list. They are useful if a prompt makes them relevant, but they should not compete with the fourteen required cases for memory priority.

  • Loper Bright Enterprises v. Raimondo (2024) overruled the older Chevron deference framework: courts now interpret an ambiguous statute an agency administers independently, rather than automatically deferring to the agency's own reading.
  • New York State Rifle & Pistol Association v. Bruen (2022) set the current historical-tradition methodology for evaluating a specific firearm regulation, and United States v. Rahimi (2024) clarified that the test requires a well-established and representative historical analogue, not an identical historical twin. Both answer a separate, later methodology question from the incorporation question McDonald answered.
  • Wolford v. Lopez (2026) applied the Bruen framework and held unconstitutional a state default rule barring licensed carry on private property open to the public absent the owner's express authorization. It does not change McDonald's required-case role.

Practice set

Exam mode

  • The exam covers 5 questions and 7 written responses.
  • A single timer of 29 min runs for the whole set.

Study mode

Study mode lets you answer each question at your own pace and shows the explanation as soon as you check your answer.

  • The 12 questions appear in a new order each session.
  • The explanation opens when you check each answer.
