"Belegbogen" stands for course record sheet. Students enter each of the lectures, seminar and exercise courses they have attended into the course record sheet. At the end of the semester, the sheet is filed in the "Studienbuch", the course record book - see under "S". Students have to present the Studienbuch to the examinations office (Prüfungsamt) - at the end of the basic study stage (Grundstudium) and main study stage (Hauptstudium) respectively.
