AP United States Government and Politics Study Guide
AP Gov centers on 15 foundational Supreme Court cases and 9 foundational documents that recur across every unit — building a real understanding of these (not just names) pays off across all four FRQ types, especially the SCOTUS comparison question.

Common Mistakes to Avoid
- Naming a foundational case or document without correctly explaining the constitutional principle it establishes — the SCOTUS Comparison FRQ specifically requires this connection.
- Confusing similar-sounding cases (a very common trap given how many 14th Amendment cases exist) — build explicit comparison notes.
- Writing the Argument Essay without engaging a counterargument, which the rubric specifically rewards.
- Treating Quantitative Analysis questions as a math problem rather than a data-interpretation-plus-political-reasoning question — the rubric wants a claim supported by the data, not just a correct reading of a chart.
