Use Digiexam for regular assignments.

Use the  lockdown mode for an assignment during your class 

By using the feature "Add media links" in an exam you can use Digiexam as a platform for your regular classes/courses. You can allow links to specific web pages, Youtube-clips and create an assignment for the students to work on, but still in a device lockdown mode.

Example:

Allow a Single web page if you want to restrict your students' access to a specific URL or use Whole domain to allow them to use the entire domain.
