>In an international survey conducted in 2003, students from forty countries were asked whether they agreed or disagreed with the statement: "When I study math, I try to learn the answers to the problems off by heart."
Is "off by heart" really a well known phrase in 40 countries? I'm from the US and this question really confused me (even though I'm aware of the phrase "by heart").
