Advanced Placement (AP) Chemistry (also known as AP Chem) is a course and examination offered by the College Board as a part of the Advanced Placement Program to give American and Canadian high school students the opportunity to demonstrate their abilities and earn college-level credits at certain colleges and universities. The AP Chemistry Exam has the lowest test participation rate out of all AP Courses, with around half of AP Chemistry students taking the exam.

Course

AP Chemistry is a course geared toward students with interests in chemical biologies, as well as any of the biological sciences. The course aims to prepare students to take the AP Chemistry exam toward the end of the academic year. AP Chemistry covers most introductory general chemistry topics (excluding organic chemistry), including:

Exam Weighting

Exam

The annual AP Chemistry examination, which is typically administered in May, is divided into two major sections (multiple-choice questions and free response essays).

Old test (2013 and earlier)

The old test was composed of two sections: a multiple-choice section consisting of 75 questions with five answer choices each, and a free-response section consisting of six essay prompts that required the authoring of chemical equations, solution of problems, and development of thoughtful essays in response to hypothetical scenarios. While the use of calculators was prohibited during Section I and Section II Part B, a periodic table, a list of selected standard reduction potentials, and two pages of equations and conventions are available for use during the entirety of Section II.

New test (2014 and later)

The 2014 AP Chemistry exam was the first administration of a redesigned test as a result of a redesigning of the AP Chemistry course. The exam format is now different from the previous years, with 60 multiple choice questions (now with only four answer choices per question), 3 long free response questions, and 4 short free response questions. The new exam has a focus on longer, more in depth, lab-based questions. The penalty for incorrect answers on the multiple choice section was also removed.

Prerequisites

The College Board recommends successful completion of high school chemistry and Algebra 2; however, requirement of this may differ from school to school. AP Chemistry usually requires knowledge of Algebra 2; however, some schools allow students to take the course concurrently with this class. The requirement of regular or honors level high school chemistry may also be waived, but usually requires completion of a special assignment or exam, or completion of high school chemistry alongside AP Chemistry.
