I know how active USC has been in recruiting URM candidates. I worked at a high school that sent a number of students to USC-almost a feeder.
My sister attended USC and she didn’t have a perfect GPA, but close, like the OP.
Sister was heavily recruited, as a URM, with similar grades to the OP and high, not perfect, SATs for close to a full ride. Our son, was also heavily recruited in multiple areas for USC (sports, academics). We knew that his NMS win was an attractor for a number of schools who wanted NM winners.
Also, USC is very active in the local community and has articulation agreements with local high schools near the campus, which are heavily diverse. Every time I’ve visited USC, there is always a tour, with local students, going on at the campus somewhere.
The OP is a URM, and although the Court decided on equality in admissions, there are ways in which this OP can discuss how her culture has evolved her interests. She’s a strong student and appears to proactive in her EC’s and it comes through.
Based on my local experiences, I think this student has a good shot at USC. She wont know until she applies. (They work really well with the families.)
Edited to add: She’s from Illinois, so that is another point in her favor with geographic diversity.
