What an AP Gov cheat sheet is (and what you can bring)

A cheat sheet here means a condensed, high-yield study tool, not something you take into the exam — the AP U.S. Government exam is closed-resource and fully digital in Bluebook. Think of this page as what you review the night before, when the best return comes from locking in the required documents and cases.

Those two lists are the highest-yield material in the entire course: the nine foundational documents and fifteen Supreme Court cases show up in the multiple choice, anchor the SCOTUS Comparison question, and supply the evidence for the Argument Essay. Know them cold and much of the exam falls into place.

The 15 required Supreme Court cases

Implied powers and national supremacy through the necessary-and-proper clause.

How to use this in your last week

Work the two lists actively, not passively. For each document and case, be able to state its main idea in one sentence and name a situation it applies to — that is exactly what the SCOTUS Comparison and Argument Essay reward. Grouping the cases by principle, as above, makes them far easier to recall than a flat list of fifteen.

Then close any gaps with the AP Gov concepts for vocabulary, rehearse the four question types with the FRQ guide, drill units with the Progress Check walkthroughs, and check a practice raw score with the score calculator.
