Hi Natalia,
The exam number is not necessary for your report -- for us, you don't really need to put any number on your report, just put the name of the course. If you really want to put some number, you can put the number of the course (08193200 "Data Science for Digital Humanities 2") or the number of the associated module (129612 "Digital Editions and Corpora 2"). We will then register the grades in the end, with the help of Dr. Moser.
Best,
Goran
