A "Studienbuch" is issued to each student when they register or matriculate. Students use this course record book to carefully enter and document all the academic papers they acquire in the course of their studies, such as certificates and credits (Studienbescheinigungen or Scheine), until they eventually de-register (Exmatrikulation/Abmeldung) from the university. Students have to present their "Studienbuch" before each examination.
