Uncertainty about the learning path

Yesterday I wanted to take the “Design Patterns” test because I thought I had completed all the necessary courses. During the test, it became clear to me that there were questions about topics that were not taught in the course. Like dark patterns for example. After some research, I discovered that there is a course on the subject of dark patterns, but it is not listed as "recommended learning" in the test and is also not included in the career path I made. The whole thing is of course very frustrating when you think you are well prepared and then find out that you haven't had half of the topics yet and that they haven't been pointed out.

I also find it very confusing that in the carrer path the Color Palette challenge is at position 4 and the Color psychology lesson, which you need for this task, is at position 12. The whole thing doesn't really inspire confidence in me and makes the whole thing seem a bit unthought out.
