What class in high school did you slack off in, and now you WISH you hadn’t? A new survey asked people to name the #1 subject they wish they’d paid more attention to. And MATH took the top spot.

Here are the top eight subjects we wish we’d tried a little harder at . . .

1. Math. 31% of people wish they’d paid more attention. 23% of men and 15% of women said it was the most useful class they took.

2. A foreign language, 26%.

3. Science, 23%.

4. History, 19%.

5. English, 15%.

6. Social studies, 14%.

7. Music, 9%.

8. Physical fitness, 8%.

Older people were more likely to say history. And young people were more likely to say music or gym class.
