Das gesamte abiturrelevante Wissen vereint in einem Netzwerk! Alle Schüler vereinen sich in einem Netzwerk, einem Knotenpunkt, einer Wissensballung. Das Wissen aller Schüler und Lehrer findet hier zusammen und steht für jeden kostenlos zur Verfügung! Nach dem Prinzip des Austausch und dem Motto: Jeder profitiert von jedem! In allen Bundesländern wird das Zentralabitur geschrieben. Das bedeutet einheitliche Themen und Abiturprüfungen für jeden Schüler und jede Schülerin. Diese zentralen Aufgaben und Themen erlauben und erfordern schon fast eine Möglichkeit des zentralen Lernens. Eine solche Möglichkeit bietet Abiunity! Hier können sich Schülern und Schülerinnen schulübergreifend auf das Zentralabitur in ihrem Bundesland vorbereiten. Doch nicht nur für Schüler ist die Abitur Community gedacht, sondern auch für Lehrer oder andere freiwillige Helfer, die die Schüler auf ihrem Weg durchs Abitur unterstützen wollen. Alles was dem Austausch dient und anderen Hilfe bieten könnte, kann hier gesammelt werden: ob Präsentationen, Referate, Texte, Hausaufgaben oder Sonstiges. Auch Fragen treffen hier auf Antworten.
