Exam Overview

The exam assesses students' understanding of the core scientific principles, theories, and processes governing chemical systems. There may be questions on the use of modeling to explain chemistry principles, the use of mathematical processes to explain concepts, making predictions and justifying phenomena, experimental design, and manipulation and interpretation of data.

Students have a periodic table of the elements and a formulas and constants chart to use on the entire exam. In addition, students may use a scientific or graphing calculator on the free-response section.

Encourage your students to visit the AP Chemistry student page for exam information and exam practice.

The Past Exam Questions page has free-response questions and scoring information from the 2013 exam and before. Please note that this page does not represent the redesigned exam. However, the question types are the same and the topics similar, making them a valuable resource for students and teachers.

Be sure to review the Chief Reader Report. In this invaluable resource, the Chief Reader of the AP Exam compiles feedback from members of the reading leadership to describe how students performed on the FRQs, summarize typical student errors, and address specific concepts and content with which students have struggled the most that year.
