Each nation has student housing, but the accommodations in no way meet demand, and they are usually appointed according to a queue system. Each nation has at least one pub evening per week, with a following night club. The solemn peak event in the course of an activity year is the organization of student balls once a year. Most well known of the nation balls (as opposed to balls organized by student unions) is the ball hosted by Göteborgs Nation - called the "Gustaf II Adolf Ball" (also known as the "GA-Ball"). Most nations also host at least one banquet per week, where a three-course dinner is served. Each nation also has different activities for students interested in sports, arts, or partying. All activities within the nations are voluntary.
