My oldest used it last year. It's a great program, but probably not for everyone (nothing is I guess :001_smile:)
There are two ways to use it, the way it is designed is to have Dive drive the program and the student uses a textbook or the Internet to round it out. On the cd are videos, a workbook, exams, answers, and a few other things which I forget. You print out the workbook and students answer the questions contained in it instead of the questions in the textbook. This is what we did.
The other way to use it is as a supplement to various textbooks, students answer the questions in the textbook and use the videos for teaching and labs.
As April said there is a syllabus online, but it doesn't correspond with any particular text. Scheduled are Apologia, Bob Jones, the Internet, and maybe one other text. We used Bob Jones.
It is not easy, ds17 would spend 1.5 hours a day, but he learned a lot. I did not use it with ds16 because he is doesn't do well with self-directed programs.
