Goal is to find 5 courses that they haven't taken, and for which they have satisfied the prerequisites
Electives count as one course found, these are added to a list of electives but not scheduled
Courses for which the prerequisites are satisfied but are not immediately considered for scheduling are added to a list of alternatives
This algorithm also attempts to schedule concurrent prerequisites together
