# Get one CourseSection

> Retrieve a single CourseSection record by its Id.

A **CourseSection** is a structural grouping that organises lessons within a `Course`. Sections represent milestones or learning stages — each section should bring the member one step closer to the course's overall learning goal.

Sections are ordered by `DisplayOrder` and can be set to unlock immediately or after a delay, using the same `UnlockType` / `UnlockAfterDays` mechanism as individual lessons:

| UnlockType | Meaning                                                          |
| ---------- | ---------------------------------------------------------------- |
| Immediate  | Section is available as soon as the member enrols                |
| Sequential | Unlocked only after the previous section is completed            |
| Timed      | Unlocked after the number of days specified by `UnlockAfterDays` |

Sections are optional — lessons can belong directly to a course without a section. However, using sections can help create a clearer learning path for members, and allows you to unlock groups of lessons at once.
