I think you're massively overestimating the quality of education in the U.S. Simple arithmetic of two digit numbers is already in the 90% mark for adults. Branching logic is completely, completely out of scope for >2 branches. It's funny you said eight year old; the US average adult reading level is 8th grade. That's a skill most use to some degree every day, just for reading signs, billboards, and text on TV. Can you imagine how rusty arithmetic must be? Completely made up, but probably generous.
