About the Exam

The exam is 3 hours and 15 minutes long and includes both a 90 minute multiple-choice section and a 105 minute free-response section. The multiple-choice section accounts for half of your exam grade, and the free-response section accounts for the other half.

Section I: Multiple Choice — 60 Questions; 90 minutes

Total scores on the multiple-choice section are based on the number of questions answered correctly. Points are not deducted for incorrect answers and no points are awarded for unanswered questions.

Section II: Free Response Questions — 105 minutes

Long Free Response — 3 Questions
Short Free Response — 4 Questions

Section I consists of 60 multiple-choice questions, either as discrete questions or question
sets, that represent the knowledge and science practices outlined in the AP Chemistry course and exam description, which you should understand and be able to apply. Question sets are a new type of question: They provide a stimulus or a set of data and a series of related questions.

Section II contains two types of free-response questions (short and long), and you will have a total of 105 minutes to complete all of the questions. Section II of the exam will contain questions pertaining to experimental design, analysis of authentic lab data and observations to identify patterns or explain phenomena, creating or analyzing atomic and molecular views to explain observations, articulating and then translating between representations, and following a logical/analytical pathway to solve a problem.

You will be allowed to use a scientific calculator on the entire free-response section of the exam. Additionally, you will be supplied with a periodic table of the elements and a formula and constants chart to use on both the multiple-choice and free-response sections of the exam.
