You can adjust the filter for selecting a specific program (e.g., Master of Science in Media Informatics), semester (e.g., summer) or language of instructions. For classes with English on demand, the language will be switched to English when an exchange student takes part. Besides taking classes, exchange students could become an intern of a research laboratory or work on a final project which would lead to a thesis at the home institution.
Additionally, projects with changing subjects are offered every semester. For details check out elective classes and projects: https://medien.hs-duesseldorf.de/studium/wahlangebote
