The researchers also found that the average SAT score of a college that rejected a student was more than twice a strong a predictor of that student's earnings as the average SAT score of the school he or she actually attended. Just being interested in attending an elite school, then, could be a positive factor in how much someone actually earns.
So go ahead, reach for the stars (or the Ivies) if you think you have a shot at getting in. If you don't, there are plenty of other schools that will be happy to have you.
