I didn't have to use any of the tutorials, I even did project 2 with out have to do the tutorials, I followed every step in the book, and it was very easy to understand and follow, i'm now starting on project 3 and 4, If I could just follow the book and turnin in the projects, I would most likely be almost done with the class due to the book being so easy to follow, and once I get started in the book I don't want to stop
