We have been doing Classical Conversations for several years and feel that the CC challenge program isn't enough. The science and history are weak, in my mind, and I have plenty of time to dedicate to a better program. I am interested in TOG, SL, and MFW. I like that SL and MFW literature books comes with the program, but I like the flexibility of TOG. I just wonder how attainable all the books are for TOG. Any thoughts or suggestions for other curriculum? We really want to be able to get our history from real books.
