Introduction
The AP U.S. Government and Politics (AP Gov) exam covers a wide range of topics — from the Constitution and federalism to global policy and foreign affairs. Many students struggle to connect these themes, but success on the exam depends on seeing how they all fit together.
This guide provides a complete review of AP Gov content, organized into the major topics tested by the College Board. Whether you’re just starting your prep or reviewing before the exam, you’ll learn how to master the material and practice effectively with RevisionDojo’s AP Gov resources.
Federalism: Balancing Power
Federalism is a cornerstone concept in AP Gov. It describes how power is divided between the national government and the states.
Key Concepts
- Dual Federalism (“layer cake”) → clear division between national and state powers (early U.S. history).
- Cooperative Federalism (“marble cake”) → overlapping responsibilities and cooperation (New Deal era).
- New Federalism → more power shifted back to states (Reagan era).
Cases to Know
- McCulloch v. Maryland (1819): Expanded federal power through implied powers.
- U.S. v. Lopez (1995): Limited federal power under the Commerce Clause.
Exam Tip: Always connect federalism to current debates — healthcare, marijuana legalization, or education.
Civil Rights and Civil Liberties
Understanding how the Constitution protects individual rights is crucial.
- Civil Liberties = protections from government interference (Bill of Rights).
