"Exmatrikulation" is the term used when students are removed the university register, the so-called "Matrikel". This normally happens when students successfully complete their studies and graduate. However, students who fail to re-register each semester (Rückmeldung) or who don't pay the semester fee (Semesterbeitrag) or who exceed the standard time to degree (Regelstudienzeit) can be struck off the register.
