For questions related to the design of a single course, say, of approximately semester length. Questions about syllabus contents, grading options, etc. Use the [curriculum-design] tag for sequences of courses contributing to a degree.

In the US, at least, a "course" is a relatively short term (few months) study of a single topic, not a "course of study" which would be a "curriculum". Use this tag for help in designing and specifying a single course, such as Data Structures. A "course" is a single unit within a "curriculum".
