My D is a junior with your same aspirations. USC SCA is her goal scenario, and she is anxiously waiting for the fall so that she can officially apply and then learn her fate. Clearly, with acceptance rates in the 4-6% range, even the most qualified applicants should balance out their dream school reaches with a # of other back-up schools.
Good luck…
