I had high respect for the online crash course, due to the shortness of days. Nevertheless, Daniel managed to impart a lot of knowledge and ideas to me. Even the self-study phases I did super gladly and voluntarily, because I was very interested in the advanced topics.
I can absolutely recommend the online course AEVO, by Dr. Daniel Büttner, to anyone who wants to learn and expand their knowledge.
Anyone who has taken this course can only become a good instructor!
