What's Tested on the AP Psychology Exam?

The AP Psychology exam has two parts: a multiple-choice section and a free-response section. You will have two hours to complete the whole test. The multiple-choice portion of the exam contains 100 five-choice (A to E) questions. You will have 70 minutes to complete this section. 

The score for the multiple-choice section of the AP exam is based on the number of questions answered correctly. No points are deducted for questions answered incorrectly or left blank. Since there is no “guessing penalty,” you should make sure you answer every multiple- choice question on the exam. 

The free-response section of the test consists of two questions, and you must answer them both. Unlike most other AP exams, you will not be given a choice of topics. You will have 50 minutes to complete this portion of the exam. Some students find writing two full essays in such a short amount of time to be difficult. 

Your overall composite score (ranging from 1 to 5) on the exam will take into account your performance on both the multiple-choice and free-response sections, with the multiple- choice section counting for twice as much. This means that two-thirds of your score depends on your performance on the multiple-choice questions, and the other one-third of your score is based on the quality of your essays. 

Each year, the exact breakdown of the percentage of people who earn each score differs. More information on score breakdowns in past years is available from the College Board

AP Psychology Exam Skills to Master

Starting with the 2020 AP Psychology test, the College Board began “keying” multiple choice items to one of 3 skills, in addition to which content area the item is addressing. 

  • AP Psychology Skill 1 - Concept Understanding: applying concepts, theories, and perspectives in context. 
  • AP Psychology Skill 2 - Data Analysis: understanding and making inferences based on numerical data. 
  • AP Psychology Skill 3 - Scientific Investigation: analyzing and explaining examples of research studies. 

Notice that Skill 1, Concept Understanding, is different from the other two skills. Every multiple choice item on the AP Psychology exam is an example of “concept understanding” because every item requires you to understand and use psychological concepts in a scenario or other context. Answering AP Psychology multiple choice items always require you to know psychological concepts well enough to define, apply, compare, or evaluate that concept in order to identify the correct answer.

Skills 2 and 3 (Data Analysis and Scientific Investigation) are different than Skill 1. These are more specific skills and apply to only a subset of the multiple choice items on the test. They relate mostly to research methods psychologists use to investigate research questions and hypotheses, as well as the kinds of statistical analyses researchers use to analyze research results.
