Hello Angeliki and Anzhelika,
Thanks for uploading the first tests of your Unit! So far they look really good.
Unfortunally we had to adapt the exercises in your unit a little bit. I uploaded the new and now correct material in the folder and added the word "NEU" in the name of the document.
Please have a look at it and, whenever you find the time, adapt the exercises in your moodle version.
Thank you very much and greetings,
Dana
