Academic courses and curriculum

In education, a course is typically a coherent package of instruction covering specific topics. It may be part of a larger program or curriculum and is often described by credit value, duration and prerequisites. Modern courses exist in-person, hybrid or online formats; "online courses" and "massive open online courses (MOOCs)" expanded access to many subjects. "Course" is often used interchangeably with "class," though "class" can refer to a particular meeting of a course.

Uses, distinctions and idioms

Many idiomatic expressions use the word: to "stay the course" means to continue to the end, "off course" means deviating from a planned route. Distinctions matter in context: a curriculum groups courses into a program, while a syllabus defines a single course. In sport, a golf course commonly has 18 holes, a basic standard in modern play.

History and notable facts

The English word derives from Old French and ultimately Latin "cursus," meaning a running or a course. Across fields it retains the core sense of movement or ordered progression, whether that is the sequence of dishes at a meal, the stages of a medical regimen, or the subjects arranged for study.
