Your module leaders are best placed to advise you about how your assignment has been set up. A resource might be set to Auto-Submit. This means that when you select the resource from ‘Get Started’ and Save it for the first time, it is automatically shared with the workplace and the following message will be shown:

You will need to tick and agree to the terms of usage to continue.
→ How do I share for assessment / submit my asset, if my workbook is not automatically submitted to the workspace?
Your tutor will be able to advise you of all the steps you need to take. If you need to submit your work manually, you can use the ‘I want to’ button to ‘share’ your work to a particular workspace using the Atlas link.
