In terms of getting “Chanced” for elite colleges / universities like USC or Emory, it is virtually impossible for others to predict what may or may not occur in your specific case. With an admit rate now of only 13%, and with 3K+ applicants with test scores in the 99th percentile among those not gaining admission, your success when applying to USC, for example, will instead likely depend on too many potential factors for anyone to correctly evaluate… making predicting admission nearly impossible.
In terms of USC, I suggest reading an excellent thread on the topic from the beginning…
I also suggest reading through the following very helpful insider’s guide to USC admissions…

As for Emory, the #s may be more in your favor vs USC, simply due to the # of applicants. But… both are highly competitive and should be consider reaches for all applicants.
Good Luck…
