You can link collections together to create a learning pathway for your users. This allows you to organise your courses into different stages and add certificates at the end of each stage.
The Next Collection feature in the collection editor allows you to choose a collection for a user to be automatically enrolled into once they complete the collection you are editing.
You can read more about the collection editor here.
Click the arrow to see a dropdown list of the other collections on your site, then select one by clicking on the collection name.
Make sure you publish your changes after you have selected the next collection.
Any user enrolled into the collection after you have published the changes will be enrolled into the next collection upon completion of the current collection.
