In our Book 5 intensive training schedule we had a block of time devoted to consulting about how to complete the book, since we had only scheduled 3 days, which would take us through lesson 8. The difficulty from my perspective as the tutor was helping the participants understand the value of going through all the lessons as a group. There was some question as to whether it is necessary practice all the lessons as a group. In the "To the Collaborators" section it mentions only doing the study unit with the help of a tutor.

However, in the last paragraph of To the Collaborators and Section 10 of the study unit, it mentions working as a group to become intimately familiar with the lessons, and practicing all the elements related to drama. So we did the skit (Why is Driving a Car Like Teaching Children's Classes).

In the end, we decided to complete our training as a study circle to thoroughly practice all the lessons, with the understanding that we could shorten it if we all were feeling sufficiently "intimate" with the material toward the end. (We have also scheduled a second intensive that will be entirely intensive with no study circle; we scheduled 7 days of 8 to 10 hours -- I do not know yet if we will actually need all of that time!)
