The courses of the current winter semester are offered in a combined form of digital content and on-site elements: while the experimental parts of the lab courses take place in the labs (under implementation of the typical COVID measures), the lectures and tutorials are run in digital form, i.e., by posting of lecture videos complemented by online discussions. Participants have to register for the courses in HISPOS by October 21. The access data to the courses in Moodle (containing all relevant further information) is emailed to all registered students on October 22.
