# Drip and course settings

> Release modules all at once, on a schedule, or sequentially.

Drip controls when each **module** unlocks for a learner. Open the course, then **Settings**.

## Choose a mode

<Steps>
  <Step title="All at once (default)">
    Every module is available the moment someone enrols.
  </Step>

  <Step title="Fixed interval">
    Release one module at a time, a set number of days apart. Anchor from **enrolment date** or a **fixed start date**.
  </Step>

  <Step title="Custom schedule">
    Set each module’s release individually (offset days or a calendar datetime).
  </Step>

  <Step title="Sequential">
    A module opens when the learner finishes the one before it. No dates.
  </Step>
</Steps>

You can also require the previous module to be complete even when using dates.

Locked lessons still appear in the lesson list, but the learner cannot open them yet. Preview as a student to check the locks.

## Other course flags

On the same settings screen:

* **Visibility** — who can find the course.
* **Certificates** — issue a certificate of completion.
* **Discussion** — allow discussion on the course.
