I do know someone who got waitlisted at UCLA and accepted to Stanford (though waitlisted at Harvard). She was definitely a special case- someone with a special obstacle through life and managed to overcome it. I guess Stanford just felt that was more important to them than SAT scores, which UCLA may have found more important. It also depends on the year you apply…if you’re one of the best tuba players in the nation, but that school doesn’t need a tuba player it doesn’t help. But if another school wants to improve the caliber of the band, you are in luck
