The e-learning covers a wide range of topics, which are broken down and explained in detail. In part, the page "Wikipedia" was consulted as a source or to deepen the knowledge. A more trustworthy source would have been desirable, such as studies or excerpts from reference books on the relevant topic, as used elsewhere to deepen knowledge. The quiz at the end of thematic units can be quite helpful to consolidate what has just been learned. Unfortunately, however, small carelessness errors have crept in here, so that answer "wrong" had to be marked in order to achieve the full score at the end of the quiz.
On the whole, however, a good way to complete the FPZ training in a self-organized manner, even alongside work!
