When in KUSSS, click on "Stundenplan" to view your current schedule of classes for that semester. Under "Vordefiniert" on the right-hand side, you can select to view your schedule by week, semester or by day.

In the right menu bar under "Mein Stundenplan" you can use the item "Bearbeiten" to create and edit a prospective class schedule showing registered classes or a schedule showing selected classes and class registrations.
These individually created schedules are only temporarily available, meaning they cannot be saved in the system.
