Can you provide a link to the test? I searched Forbes but I haven't found it so far. I want my family to take the test. Since we range in age from 7 to 45, this should be a decent test for a Midwestern family.
Of course, homeschooling our children, at least through 8th grade, means that we will blow the curve. Oh well, maybe my youngest daughter will miss a question to keep the people that Forbes tested from feeling too bad.
My kids are in public school and know geography pretty well ---partly because they learn map reading on family trips to different states. If these kids don't know where the Pacific Ocean is, it's very doubtful their parents know where it is ---also these kids are the kids likely to have children quite soon themselves ----homeschooling only works in the families whose kids would do okay either with homeschool or public school. I can't imagine what homeschooling would do these kids.
