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

Know the documents and cases

The course has 9 required foundational documents (such as the Declaration of Independence, the Constitution and Federalist No. 10) and 14 required Supreme Court cases.

Section I

The multiple-choice section

55 questions in 80 minutes gives you about 1 minute 27 seconds per question. Stimulus-based sets (graphs, excerpts, maps) take longer, so pace yourself. Wrong answers lose no points.

Strategies that work

  • Read graphs for the claim they support. Many questions ask what a chart shows, not what you think is true.
  • Know each required case by its facts, the constitutional clause involved and the holding.
  • Match the concept to the scenario: federalism, checks and balances, or separation of powers?
  • Watch the exact wording: "formal" (in the Constitution) vs "informal" (developed through practice) powers.
  • Eliminate extreme answers with words like "always", "never" and "only".
  • Flag and move on after 2 minutes. Return once the quick points are banked.
What the course covers

Unit 313–18%

Civil Liberties & Civil Rights

Board of Education, Citizens United v. FEC, Baker v. Carr and Shaw v. Reno.

Section II

The 4 free-response questions

100 minutes, 4 questions, each worth 12.5% of your score. The four question types are the same every year.

Q1 · Concept

Concept application

Read a scenario and explain how it connects to a political process, institution or behavior, then describe an effect or interaction.

Name the concept, then link it to a detail in the scenario.

Q2 · Data

Quantitative analysis

Describe the data in a chart, identify a trend, draw a conclusion, and explain how it relates to a political principle.

Quote specific numbers from the chart; vague trends score less.

Q3 · SCOTUS

SCOTUS comparison

Compare a non-required case you're given with one of the 14 required cases: the facts, the clause, and how the holdings relate.

Name the constitutional clause the two cases share.

Q4 · Argument

Argument essay

Take a position, support it with two pieces of evidence (one from a foundational document), and respond to an opposing view.

Use a document from the list in the prompt; it's required for full credit.

Time plan: About 20 minutes each for Q1–Q3 and 40 minutes for the argument essay. In the essay, the rebuttal is a separate point: name an opposing view and explain why it's weaker.

Habits that earn points

  1. Answer each lettered part separately and in order.
  2. Name the concept, then apply it to the scenario.
  3. Quote numbers from charts; don't describe vaguely.
  4. In SCOTUS questions, name the shared constitutional clause.
  5. Stuck? Define the concept accurately; it can still earn a point.
Learn from others

10 traps that cost points

  1. Incorporation confusion

    The Bill of Rights originally limited only the federal government. Selective incorporation through the 14th Amendment applies most of it to the states.

  2. Formal vs informal powers

    Formal powers are written in the Constitution (veto); informal ones developed in practice (executive orders, signing statements).

  3. Liberties vs rights

    Civil liberties protect individuals from government; civil rights protect against discrimination and ensure equal treatment.

  4. Mixing up the case clause

    Tinker is free speech; Engel is the establishment clause; Yoder is free exercise. Know which is which.

  5. House vs Senate powers

    The House starts revenue bills and impeaches; the Senate confirms appointments, ratifies treaties and tries impeachments.

  6. Describing instead of explaining

    "Explain" needs a how or why. Describing what happened is not enough.

  7. Ignoring the chart

    In Q2, answers must use the data shown, not general knowledge.

  8. Missing the rebuttal

    In the argument essay, responding to an opposing view is a separate rubric point.

  9. Interest groups vs parties

    Parties try to win elections and control government; interest groups try to influence policy.

  10. Federalism terms

    Categorical grants come with strings; block grants give states flexibility; unfunded mandates require action without money.

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 · Federalism

    In McCulloch v. Maryland (1819), the Supreme Court relied mainly on which constitutional provision to uphold the national bank?

    • A The necessary and proper clause
    • B The commerce clause
    • C The Tenth Amendment
    • D The supremacy clause alone
    Show answer

    Answer: A. Chief Justice Marshall held that the necessary and proper clause allows Congress to use implied powers, such as creating a bank, to carry out its enumerated powers.

  2. Unit 2 · Presidency

    Which is an informal power of the president?

    • A Vetoing legislation
    • B Issuing executive orders
    • C Serving as commander in chief
    • D Granting pardons
    Show answer

    Answer: B. Executive orders are not listed in the Constitution; they developed in practice. The other powers are formal powers in Article II.

  3. Unit 3 · Speech

    Students wear black armbands at school to protest a war. Under Tinker v. Des Moines, the school can ban this only if:

    • A the speech would cause substantial disruption of school activities
    • B the protest is unpopular
    • C the students are under 18
    • D the war has been declared by Congress
    Show answer

    Answer: A. Tinker protects student symbolic speech unless it substantially disrupts school activities.
