Norway's Serie B League Group A adopts a double round robin competition system (each team plays with other teams twice as a host and away team respectively). The calculation method of points in a single game is that the winner gets 3 points, the loser gets 0 points, and both sides get 1 point in a draw. Finally, the ranking order is based on the number of points. If the points are the same, the ranking is based on the number of goals won or lost. The champion of the league will be directly promoted to the Serie A next season, and the second place will participate in the upgrading play off with the second place in Group B. The last three teams will be demoted to the Serie C next season.
