Yes, I am beefing up the upper grades’ assignments for those modules as part of the revision. With the new plans, each module will count for 1/2 credit of world history/geography and 1/2 credit of Bible, or if you prefer, you can combine those for 1 full credit of world history, since the Bible portion is focused on the history of Ancient Israel. Your decision.
By the way, I am planning to include a page in each lesson plan book that outlines credit suggestions and calculations for that year of study to, hopefully, make that information more readily available for everyone.
