I have used their reading lists. I tried to enroll in an adult version of their Great Books discussion list, but there wasn’t enough interest and it was closed.
Another site you might look at is the Hillsdale K-12. The entire curriculum is available for download and it is free. It is quite comprehensive and challenging.
Oh thank you. I love having that kind of thing available for reference and ideas.
Great advice! I’ve been collecting the Hillsdale curriculum for years by purchasing on ebay and amazon. Many of the books are out of print, but they are excellent!
