Never mind U.S. High School students, how about us adults? Honestly, I didn't score well with this test either...
Let's not blame the U.S. educational system outright, I believe much of the blame has to be owned by us parents. Over the past 20 - 30 years, we've allowed ourselves to buy in to the notion that certain people know better than us. Sometimes that true, but God has endowed every single mom and dad with certain gut instincts about each of our particular children.
