About AP Psychology

AP Psychology introduces students to the systematic and scientific study of human behavior and mental processes. The course covers five major content areas — from the biological machinery behind thought and emotion, to how we learn and develop, to the social forces that shape our behavior, and finally to what happens when mental health breaks down and how to treat it.

The College Board organizes the course into 5 units, weighted unevenly on the exam. Unit 3 (Development & Learning) is the largest at 20–26%, followed closely by Unit 4 (Social Psychology & Personality) at 22–26%. Units 1, 2, and 5 each account for 13–24%. The exam itself consists of multiple-choice questions and two free-response questions (FRQs) — both of which require you to apply psychological concepts to novel stimulus scenarios, not just recall definitions.

Every resource on this site is aligned to the College Board’s official AP Psychology curriculum framework and completely free. The MC practice questions include stimulus passages just like the real exam. The FRQ practice walks through the specific action words — identify, describe, explain, propose — that determine how to answer each part, with rubric-based self-check answers so you know exactly what earns the point.
