Tom Farber gives a lot of tests. He's a calculus teacher, after all. So when administrators at Rancho Bernardo, his suburban San Diego high school, announced the district was cutting spending on supplies by nearly a third, Farber had a problem. At 3 cents a page, his tests would cost more than $500 a year. His copying budget: $316. But he wanted to give students enough practice for the big tests they'll face in the spring, such as the Advanced Placement exam.
"Tough times call for tough actions," he says. So he started selling ads on his test papers: $10 for a quiz, $20 for a chapter test, $30 for a semester final.
