This course is not recommended for beginners, the author assumes previous knowledge from the student and start to talk directly about how to use the tools and strategies, which does not make sense if you are learning at a beginners level. Additionally, he mentioned that if we do not have the knowledge about the subject he is explaining, then we can check his other course and buy them where he explain in detail the concept. I believe this approach is not honest, as I though this course will show me the foundation theory and understanding of the main concepts before I start to apply them. I am disappointed. The course is probably good but not excellent, for people with already experience in the field.
