courses

I was stumbling aruond drupal.org and found two modules: http://drupal.org/project/content_complete and http://drupal.org/project/complete

Now I'm not entirely sure if either will do what I want but it seems like both at least are heading in the right direction. I'm looking for some kind of if/then logic in that when a user completes task x they get %y added to their total. In my use-case it's % completed of a course or lesson. Has anyone else used either of these projects or do any kind of user progression tracking?
