I also have a sad, sad, situation like this. Once, in the 7th grade, when a girl (who was part of the "popular group,") was caught socializing, and told to identify Cuba on a map, right after we took a quiz on the Caribbean. She was utterly stumped, and stared at Patagonia for a couple minutes until the teacher started laughing.

And I agree that urban schools aren't necessarily the best. I go to a High School ranked in the top 50 within the United States, and ask anyone in the halls who wrote Harry Potter or the Lord of the Rings, and most likely, they won't know. Same goes if you ask them what the chemical formula for table salt is (everyone has to take at least a semester of generalchemisrty). Although if you ask then about Disney, or Celebrities, they could probably tell you everything that's possible to know.
