Good teacher with a lot of knowledge and good examples. Goes through the material in a nice and structured way. The questions in the course powerpoint are a good way to apply the material just learned as well. The course itself was highly recommended. The online exam trainer is less so. I myself saw, from what I suspect, 3-4 errors in the questions. These were shared with the teacher. Furthermore, I miss the option on per chapter questions. So that after a class day, if you want to practice more of a specific topic. the ability to do so online. That way, you also get used to the question quickly. So I would like to see the option to take practice questions by chapter and the option to take a practice exam, of the entire book.
