From Malcolm Gladwell’s new book David and Goliath (iBooks version):

“If you get As in school, you never need to figure out how to negotiate your way to a passing grade, or to look around the room as a nine-year-old and start strategizing about how to make it through the next hour.”

They are talking about grades, someone missed the missing apostrophe.  The book is good, but I am a Gladwell fan.  He makes some good points.  I like the way he looks for the boundaries of things.  This one reminds me of Outliers.
