Students must be manually added to the alumni list when the course is completed. Alumni continue to have access to the course after it is complete. Instructors need to decide whether they want past students to have access. Automatically adding them would create problems for the majority who do not maintain alumni lists.
SCOs are not handled like regular ATutor content. They are indepedent units that run outside the ATutor tracker. They are more intended to be content units rather than an entire course (although entire courses do exists). Data is stored in the sco database tables, thought the tools to retrieve the data have not been created yet.
To remove a course from a student's course list, they need to be remove manually from the course enrollment list.
Tracking completion of courses is not something that would be easy to implement, since a definition of complete can vary significantly across courses. In the interest of leaving ATutor adaptable to what ever teaching stategies an instructor might use, we're unlikely to add an automatic course complete function since that would limit how one defines complete. From the users perspective, SCO tracking is displayed in the bullets that precede an items in the sco table of contents once it has been open through the Packages tool. red, yellow, green
