One of the major perks of Skool is to be able to create courses. AND it is to your benefit that your members be able to hit 100% completion on your courses.
But when you create a wild goose chase sending people out of the module with outbound links then they may never hit 100% completion.
Your stats tell the story.
If you're not getting 100% user completion - then you probably have outbound links. Ya gotta take ownership - get real - think about your member's user experience.
