I am currently in the course. It covers both photography and business aspects. the initial assignments are rather basic, covering very specific single aspects of photography such as DoF or selective focus. Later lessons are more complex assignments covering different areas of photography, from portraiture, sports, architectural, etc. So you get exposure to different areas should you not know what or how to shoot that area. Each assignment is critiqued.
Is it great? No. It is a good general course covering a broad area that will make you work to improve and explore your photography.
