Just bumping you:) I believe it used to be one world history credit for the first three guides (ancients), one credit for 4th (MA/Ren/Ref), and 1/2 American and 1/2 World for both guides 5 and 6. The first three guides have a lot of Bible. If you did a separate program for that you could potentially just do the history in the three guides in one year with a high schooler. But with the new guides coming out that may be different! As far as how many credits, I don’t have a high schooler yet….but I think it depends on your state and where they might attend college. Hopefully others will chime in:) Blessings, Gina
