Each time you want to duplicate a challenge, you must first add a new ChallengeMe activity to your course. You can then duplicate an existing challenge to avoid having to reconfigure everything from scratch.

Here is the procedure to follow:

• Add a new ChallengeMe activity to your course (See the guide)
• Click on this activity
• Click on “Create or duplicate a challenge”
• Click the “Duplicate an existing challenge” button
• Select the challenge to duplicate from the list

The settings from the duplicated challenge will be loaded into the new one. You can still edit them if needed.
