Chances at Ivies and UC's?

Your GPA is really good and activities are very impressive, but your SAT score is not as good as the rest.
I think you will have more chance on USC and since you are a resident I think you have a good chance for UCLA. Everybody who applies to ivies are so good in everything including in standardized tests, and if the school recommends SAT subject test scores it’s better to have a higher score for them.
Anyway good luck!
