I just got my SAT scores back. I got a 2300 (750 CR 800 M 750 W 10 Essay). If I am aiming for top business schools, such as Wharton, or just Ivies in general, is it necessary for me to retake the SAT? And should I still take the ACT? I have heard different thresholds as to when Ivies start viewing scores as equal, from 2200, 2250, and 2300, which is why I am not sure how much retaking will benefit me.
