Es erlaubt Ihnen, den ungefähre endgültigen Durchschnitt zu kennen. Sie wird auf eine vom Anwender in den Anwendungseinstellungen gewählte Weise berechnet. Es wird empfohlen, die entsprechende Option zu wählen. Das liegt daran, dass die Berechnung der Schuldurchschnitte unterschiedlich ist. Wenn Ihre Schule den Durchschnitt der Fächer auf der Vulcan-Seite angibt, lädt die Anwendung diese Fächer herunter und berechnet nicht den Durchschnitt. Dies kann geändert werden, indem die Berechnung des Durchschnitts in den Anwendungseinstellungen erzwungen wird. \n\n<b>Durchschnitt der Noten nur aus dem ausgewählten Semester </b>:\n1.
