We used the first SCM guide this year for our Bible time. Since it wasn’t for history (we used TQ middle ages and ren/reformation for that), I didn’t consider adding more. So I can’t really answer that.
At this point, I plan on using the second SCM guide for our Bible this next year. By using the SCM guides, we combine Bible history, ancient history and geography as well as theology and scripture memory into our Bible time.
