Chemistry is a category of physical science that deals with the structure, composition, and various properties of matter. Some topics which chemistry aims to cover include the formation of chemical bonds, properties of atoms, and the intermolecular forces responsible for giving matter its unique properties.

A course is the study of a particular topic within a wider subject area and is the foundation of a qualification. A typical course includes lectures, assessments and tutorials.

Part-time learning allows one to obtain a degree or qualification even if one cannot attend school on a full-time basis. One can learn at one's own pace, gradually accumulating credits that count towards a final qualification.
