We have a group of 7 moms interested in doing History and Literature as a group using the TOG Y3. They are still deciding whether to purchase the whole program or pay the per class fee. My question is this: Has anyone come up with a shorter list of books to use? Obviously we won't all be able to get the same books from the Library, and the DI history total comes to 326 (UG) or $373 DI. Has anyone made a short list that works?
