Java for Kids is a self-paced course.  The suggested approach is to do one class a week for ten weeks.  Each week’s class should require about 3 to 6 hours of your time to grasp the concepts completely.  Prior to doing a particular week’s work, open the class notes file for that week and print it out.  Then, work through the notes at your own pace.  Try to do each example as they are encountered in the notes.  Work through the projects in Classes 3 through 10.  If you need any help, all completed projects are included in the JK Code folder.
