The tests are outdated
The tests are outdated, poorly programmed, have random errors that mess with the end results. There are mistakes (not just spelling) in the learning materials and there is no straightforward reporting option, should one encounter an issue. The designers of that website should take the ICDL course themselves, as it clearly feels that they didn't. If you want to learn ICDL (in German) any other resource (such as using the software for two weeks in combination with any search engine) is a better way.
On a positive note: the website design is good enough to not get lost. 🤪
