Welcome to the board!
We do plan for Preparing to be completed before the 4 year history cycle, if that is where your kiddos place language arts, math, and age-wise. Our guides are designed for you to be able to enter at any guide, as placement is mainly based on the 3 things I just mentioned.
If you are using your own language arts and math, then you'd have a little more flexibility into which of our guides you'd use.
We are releasing our guides at the pace of one per year. Our newest guide will be out next year by this time. It will be a guide for the ancient time period covering Creation to Christ (including the beginning of the spread of the gospel).
We DO need to get our long-range plans up on the website, but you can see them in our new catalog which can be ordered here:
