Is is possible to get into a very good college such as USC, Duke, etc with a 3.4 gpa?

i am very involved in many extracurricular activities such as orchestra volleyball, basketball (school and AAU), track,student council, i have many volunteer hours, i also have a full time job. Ive taken all Pre-Ap cles since freshman year. I am an African American female. i am also in the top 25% of my cl. Oh and i have not taken the SAT or the ACT yet and i am a junior.
