Due to Overlapping for Registered Courses
You may have possibly selected classes in which the times and/or dates overlap. In this case, this may be the reason you did not get the class you wanted.

Exceeding the Limit of ECTS Credits for Your Selected Program
It is possible to register for courses and exceed the ECTS credit limit. Course, however, will only be allocated up to the maximum extent of the program. Waiting lists and direct allocation can exceed the amount of stated ECTS credits. Please note: If additional courses (allocation according to priority number) are to take place afterwards, all previous allocations (also direct allocations and allocation according to sequential order) will count!

Registration Not Saved
You may have possibly not clicked to save your registration and have therefore not fully completed the registration process to sign up for those particular classes. Check KUSSS under "Meine Anmeldungen" to see if all of the classes you are signed up for are actually listed there.

Classes Have Already Been Allocated Within the Same Course Class
If you have already been allocated to a course, you cannot sign up for another course that has the same course content. You can find information on course content and the course class (the code is located in brackets next to the course title) in the course's header for each course.
Each institute can decide whether or not they want to add students and they can do so manually.

Cancelled Course
The course you registered for has been cancelled (when, for example, not enough people have signed up).
