Electives

In higher education in various countries, such as Canada, Israel, Nigeria and the United States, a course is a unit of teaching that typically lasts one academic term, is led by one or more instructors (teachers or professors), and has a fixed roster of students. A course usually covers an individual subject. Courses generally have a fixed program of sessions every week during the term, called lessons or classes. Students may receive a grade and academic credit after completion of the course.In India, the United Kingdom, Australia and Singapore, as well as parts of Canada, a course is the entire programme of studies required to complete a university degree, and the word "unit" or "module" would be used to refer to an academic course as used in North America and the rest of Europe. This corresponds roughly to an academic major in the United States system.
In South Africa, a course is officially the collection of all courses (in the American sense, these are often called "modules") over a year or semester, though the American usage is common. In the Philippines, a course can be an individual subject (usually referred to by faculty and school officials) or the entire programme (usually referred to by students and outsiders).
Courses are time-limited in most universities worldwide, lasting anywhere between several weeks to several semesters. They can either be compulsory material or "elective". An elective is usually not a required course, but there are a certain number of non-specific electives that are required for certain majors.
