Since my kids are only 5-14, they haven't had much of a chance yet. But my oldest son (then 13) got to take the SATS last year and my daughter is taking them this year at 12.
I took them my junior year of HS and got a 1200, which was good enough for UConn at the time so I didn't bother taking them again my senior year. My son beat me (even if you only count the math and verbal) and I'm sure my daughter will, too.
They've gotten to root for the World Series Champion Boston Red Sox, Super Bowl Champion New England Patriots, NCAA Basketball Champion UConn Huskies (Men's and Women's) and NHL Champion Boston Bruins as a kid. They either sucked or were so-so when I rooted for them when I was their age. The Celtics were better back then, though.
One thing that we both got to do was learn how to drive a car and operate a backhoe at 13yo at our place in Maine with my father as instructor.
