Hello, Our kids were enrolled in SCVCS for about a year. There is no fee and they were enrolled mid-year last year. They shipped all the materials to the house. If you qualify, they will send/lend you a computer. I do not know the details of that system. Overall, it was a very good program.
Our issue with them was you didn't have the same flexibility as a traditional home school (because it is not one). My wife needed surgery in Mid-Oct and needed a couple weeks of flexibility and it was going to be difficult to work out. You have to log a certain amount of hours. If not for that, we would probably still belong.
Please PM me with any other questions as I'll forward them ot my wife. She taught for many years and has a good understanding of all this stuff. I just go to work.
