I bought the annual membership, because the trial course seemed too easy.
I wanted to learn graphic design. I am at a beginner level, I don't really know how to use adobe programs, nor do I have professional training in design. As I saw that the graphic design had 4 modules I decided to go through with all of them because the first (free) module was too easy, but I hoped that it would get more interesting in the later modules. Unfortunately, it didn't. Since I had purchased a yearly subscription I decided to try their advanced graphic design course. In the first lesson, they again talked about the colour wheel and they did so on such a beginner level! It is what everybody knows already from their "graphic design" class, or if you go and google is what the first thing you read. I am really disappointed. I think this is the course for those who really have no experience with anything digital. But then don't call it a professional diploma in graphic design, because it is sooooo far from it.
