X-Tutorials are implemented in the form of research tutorials. They are not capacity neutral, but they are low capacity: They are typically not credited in one subject, but in the elective area: überfachlicher Wahlpflichtbereich (üWP) / freier Wahlbereich/ Wahlpflichtbereich/ Studienbereich Allgemeine Berufsvorbereitung (ABV). They are therefore not recognized for a specific course of study, but rather across the entire range of courses offered by the university. In coordination with the AG BUA Studierende and the BUA Büro, a specific module was developed for this credit.
