The Advanced Placement Chemistry (AP Chemistry, AP Chem) examination is offered by the College Board as part of the Advanced Placement program. The exam is designed to give American and Canadian high school students the chance to demonstrate their skills and earn college-level credit. Our free AP Chemistry practice exam allows candidates to revise the complete topic spectrum for the actual exam. Our simulator presents multiple choice questions in a friendly 15 questions exam which follow the actual exam closely. Our free practice exam covers areas of Chemistry including states or matter, reactions and structure of matter. As with all our exams, this exam is free for all users. You are also free to take the exam as many times as you wish to improve your chemistry skills and understanding.

The course material for AP Chemistry is comprised of the following categories:

Reactions
Chemical equilibrium
Chemical kinetics
Stoichiometry
Thermodynamics

States of Matter
Gases
Liquids
Solids
Solutions

Structure of Matter
Atomic theory, including evidence for atomic theory
Chemical bonding, including intermolecular forces(IMF)
Nuclear chemistry

The prerequisites by the College Board include completion of High School Chemistry and Algrbra.

The AP Chemistry exam is usually available during May of each year. The exam itself is divided into two major sections – multiple choice and free response essays. The multiple choice section is made up of 75 multiple choice questions. Candidates cannot use a calculator during the multiple choice test, or any reference material.

Our questions are of the form:

Q1. A chemical reaction is the result of collisions of sufficient energy. The rate of reaction is the rate at which these effective collisions occur. In this context , what does the collision frequency depend upon?

A1. how closely the particles are crowded together
