Will I get into the University of So. Cal (USC)?

Your GPA is excellent, continue like you did in Junior year. The only thing in your way is your SAT scores aim at least for a 1800 which is a dramatic jump but it is possible if you attend SAT courses and study with Sparknotes, definitely retake them and take the Math SAT II will be big plus. Also, a lot of extracurriculars will help your chances a lot too and the fact that your dad attended USC should help.
