# Pre-Fetching Supervision Tasks

When you enter a Supervision task from **Tasks** > **Perform Tasks**, Hyperscience automatically assigns you 10 tasks and pre-loads those images in order to reduce browser latency. New tasks are pre-fetched only when there are fewer than five tasks remaining in your browser queue.

## Returning tasks

Keyers are not able to work on tasks already assigned to another user. There are two ways that a task can return to the queue to be re-assigned:

1. If you do not complete the task within 4 minutes after starting it. This time period can be configured by the system admin; the default is 4 minutes.
2. If you exit a current task, return to **Tasks** > **Perform Tasks**, and then re-enter a Supervision task. This will pre-fetch 10 new tasks.
