Wow! In my opinion I don’t see what else the admissions office at UCI could be looking for!! Like some said above, you could try to possibly bump up your SAT score by retaking one, or even trying the ACT, but I truly don’t think your current score is one that would cause the admissions to reject you. As for Pepperdine, I’d say that you have a very likely shot of getting admitted - problem is is that their big academic merit scholarships go to students with crazy high SAT Scores (although your GPA is perfect), so even though you’d most likely get admitted, paying for it could be a future issue. But your stats are very impressive, and I’d be shocked if you didn’t get into UCI. Good luck and I hope everything works out for you!!
