ILIAS stands for "Integriertes Lern-, Informations- und Arbeitskooperations-System" (a German open source learning management system) and is the internet-based learning platform of the university. Most lecturers use ILIAS to share teaching and learning materials of their course with students. You can log in to the ILIAS platform using your student account. You should have access to your courses automatically after successful registration via C@MPUS.
