- Course is the broadest term for the study of a subject. It could be used to refer to an entire degree program, but it is most appropriately applied to a specific subject such as First Year English Literature.
- Class is more specific and is most properly applied to a section of a course taught by one instructor to one group of students at a certain scheduled time.
- Lesson is the most specific and implies a particular unit of instruction, such as would be delivered by a particular instructor to a particular class on a given day.
