Why do men outperform women on the SAT? The SAT's supposed to predict college grades. Women do better in high school and they do better in college. What's the problem here? Ah, the more you use, the more you start accepting that the SAT's coachable, the more problems you have with it.

I played street hockey in Riverside Park when I was a kid. I played goalie. I didn't make the hockey team in college, so I played lacrosse instead.
