Since the introductory week for new international students could not take place this semester, Göttingen International has created a website where the various information is presented as an online tutorial (Study in Göttingen, (Surviving) Life in Göttingen, FlexNow, StudIP, Living in Göttingen): https://www.uni-goettingen.de/en/623575.html
These tutorials are certainly very helpful for a good start in studying at the University of Göttingen.
