AP Psychology covers 6 units, from *Science Practices & Exam Questions to Mental and Physical Health. Review each unit with study guides, practice questions, and key terms — compiled by AP educators and updated for the 2027 AP exam.

AP Psychology is an introductory college-level course on how biology, thinking, development, social forces, and health shape behavior. You will interpret research, analyze data, and apply concepts to real situations.
AP Psychology is one of the more approachable AP courses, but it still takes steady effort. The biggest challenge is the volume of vocabulary and the need to apply terms to new scenarios rather than abstract math. Because the content connects to everyday life, a lot of it clicks naturally. If you keep up with terms across all five units instead of cramming, the exam feels very doable.
Start by working through the five units in order, beginning with Biological Bases of Behavior. After each unit, build a running vocabulary list and quiz yourself, since terms build on each other. Mix in practice questions to test whether you can apply concepts, not just recognize them. Then add the science practices and short FRQ writing reps so the Article Analysis and Evidence-Based formats feel familiar before exam day.
All five units carry equal weight, each making up roughly 15 to 25 percent of the multiple-choice section. That means you cannot skip or rush any unit, from Biological Bases of Behavior through Mental and Physical Health. Plan your review evenly across all five rather than betting on one topic. Concept application is the most heavily tested science practice, so prioritize using terms in new scenarios.
The free-response section has 2 questions worth 33.3 percent of your score, with 70 minutes total. Question 1 is the Article Analysis Question, where you analyze one summarized study, identify research elements, and interpret basic statistics. Question 2 is the Evidence-Based Question, where you propose a claim and support it using three summarized sources plus course concepts. Practice both formats so the reading periods and task verbs feel routine.
AP Psychology builds four science practices: Concept Application, Research Methods and Design, Data Interpretation, and Argumentation. On the multiple-choice section, Concept Application is weighted most heavily at about 65 percent, followed by Research Methods at 25 percent and Data Interpretation at 10 percent. The free-response section assesses all four, including Argumentation. Practicing these skills with real research summaries helps you read studies and back claims with evidence.
