Clicking just two links will take you to the “Subject” (Studienfach) level, where you can see all courses offered in this subject from within the study regulations selected. This page may be very long in some cases. To limit the results, use the filter functions to choose a specific “phase” or even a “concentration” (Schwerpunkt) for your program. This will shorten the list right away. The filter function also tells you how many modules are included in the relevant area.
