I imagine it would be difficult to find homeschooling curriculum that works well for your specific needs. Reviews like this, I'm sure, is invaluable to many home school families in helping them find the right curriculum. Guest Hollow looks like it would work great for many families.
I would be interested to see how you tweak Guest Hollow's Gov., Econ., and Fin. and what you decide to include for your rising 8th grader. I'm planning to do that with my rising 8th grader as well. As I was flipping through the curriculum last week I realized there will be some challenges with the course load, plus the subject matter that I will have to navigate through in my selection of what he does. I would like to do it as a family subject with my high schooler, and I'm not quite sure how it will look yet. I've considered taking 2 years to allow my mature 8th grader time to mature even more as we work through the course, but I'd love to see how another family navigates a similar challenge with Guest Hollow's Gov., Econ., and Fin. TIA. 🙂
