My son is a rising senior who is planning to major in Economics. We used Economics in a Box (used in by My Father's World) and LOVED it! Again, very free market. The curriculum includes chapters from the book Money, Greed, and God, which I found helpful in reconciling my faith and my free market beliefs. I could not recommend it more highly. This year my son will take AP Micro & AP Macro Economics online through Patrick Henry College.
We loved the Uncle Eric books in elementary/middle school as well. We used Sonlight's plan for Economics in high school, the core of which is Thinkwell. We've used Thinkwell for high school math, physics and economics. I can't express how much we love it! Landon took Thinkwell's Calculus course followed by the AP Calculus BC test and scored a 5. I have no doubt he could have done the same on the AP Economics test, but he didn't need that particular college credit.
Thank you. My head's been swirling with so many different options, this included. Your opinion of it just moved it up my list.
For all classes on the transcript, I recommend either a whole or half credit, not smaller or larger. Here an easy to remember "formula" for dual enrollment college classes:
