Sports. The only people from our high school who were accepted to Stanford when my son applied had SAT scores in the 1200s (out of 1600 - this was in 2007 and writing had just been introduced). No one with a 1300+ had ever been accepted. My son added to those rejection numbers with a 1570 and so did a number of other academic superstar kids that year. Now that Stanford has gotten more popular their numbers may have gone up, but they still need a football team.
Superscoring didn’t improve either of my kids scores more than 10 or 20 points btw and my math kid did better in CR every time.
