In terms of getting “Chanced” for USC, it is virtually impossible for others to predict what may or may not occur in your specific case. With an admit rate now below 13% and falling, and with 4K+ applicants with 4.0 unweighted GPAs and test scores in the 99th percentile among those not gaining admission, your success will instead likely depend on too many potential factors for anyone to correctly evaluate… making predicting admission nearly impossible.
Instead… it will likely come down to a composite and holistic analysis of your stats coupled with writing ability / essays, ECs, potential leadership roles, potential other unique qualifiers (URM, First Gen, geography, demographics, etc.), your Why USC? explanation/reasoning, etc.
I suggest possibly reading an excellent thread on the topic from the beginning…
Moreover, it may be best to just read through the following very helpful insider’s guide to USC admissions…
