How is the timetable created and when is it published?
You are free to assemble your own schedule (this may not apply to some fields of study at the Faculty of Medicine and some combined studies) just by registering or enrolling in courses and signing up for seminar groups.
The publication of the timetable of individual courses takes place at different faculties at different times, again according to the Term Calendars by Faculties.
Keep only the courses you really want to take in a given semester in your schedule. For courses that are held at another faculty, be sure to allow some time for transferring.
There may be situations where you have conflicting courses in your timetable. If you can't resolve this, for example by moving to another seminar group, you have to consider which courses to keep in your timetable and which to postpone to the next semester, so that it doesn't cause you too many complications in your next pass through the study.
