You can use the moodle e-learning platform to register for the courses/topics in which you are interested using your user name and password (university account). As soon as at least ten people have registered their interest in a course, a corresponding date will be coordinated and announced.
+++ Attention, update +++
Due to lack of registrations, no courses are planned for September yet. However, the courses remain open for registrations. The computer centre will schedule a date for the respective course as soon as there are ten registrations.
