+Liebe Prüfende,
+
 ich habe gerade die Räume ins ZPA gepusht. Bitte schauen Sie auf https://zpa.cs.hm.edu/teacher/exam_plan/ ob das so für Ihre Prüfungen passt.
 
 Ich habe versucht die Raumnutzung sehr zu optimieren, daher gibt es z.B. mehrere kleine (unter 10 Anmeldungen) Prüfungen in einem Raum oder ein Raum für eine Prüfung ist gleichzeitig Reserveraum für eine weitere Prüfung.
