Neuer Assistent (Einstieg im Zeugnisnoten-Dialog) geht die Lerngruppe Schüler für Schüler durch: berechnete Note mit ungerundetem Wert und Teilbereichen, Mitarbeitsgraph abschnittsweise oder als Verlauf, Arbeiten und Einzelnoten. Das 1. Halbjahr erscheint im 2. Halbjahr nur als Kontext. Die Endjahresnote wird jetzt in Dialog und Assistent aus den Halbjahresnoten verrechnet (gemeinsamer ReportGradeCalculator). In Klasse 10 kommen Projektprüfung, schriftliche/mündliche Abschlussprüfung und zusätzliche mündliche Prüfung hinzu, gewichtet nach Oberschulverordnung und PrüfV Sek. I; gerundet wird dabei bewusst nicht automatisch. Die Zeitleisten-Erzeugung des Mitarbeits-Assistenten liegt dafür im gemeinsamen ParticipationTimelineBuilder.
