Registration in this CMS is required until October 31, 2025. LSF exam registration is required to participate in the exams (and will be possible until 1 week before the final exam). Please contact your Prüfungsamt for any problems with LSF registrations. Only for Erasmus students a registration solely on CMS is sufficient. Any other student cannot write the exam unless registered on LSF. We cannot register you on LSF.

Mental Health
Being a student is challenging and might be very overwhelming. If you need support during times of struggle, reach out to friends, family, or faculty you trust. The student union at UdS also offers a counseling service that you may contact. You do not have to go through this alone! If for whatever reason (e.g., a personal emergency) you cannot attend the lectures or deliver your work in time, please let us know and we will make appropriate arrangements.
