When upwrds of 90% of srtudents fall into the categories I described, I can't give a whole lot of credence to your statements of certainty.

I would suggest you do a bit wider research on the subject than just your personal observation kind.

Do you have a link? How many where tested, who performed the test, and which areas were sampled?

Because saying 90 percent of those coming out of public schools don't know the century that the Civil War took place is a pretty tall claim.
