Unsending scores?

<p>Stupidest mistake of my life. So I have a 30+ ACT score I'm sending to USC and when I was sending my SAT2s to USC, I forgot to uncheck my horrible 1800-1900 SATs from last year from the score report so I accidentally sent USC my 700+ SAT2 INCLUDING MY 1800s SATs which is terrible. Is there any way for me to undo this or did I basically kill my chances because there's probably going to be some confusion at the office as to why this applicant has an 1800 SAT score but also a 34 ACT. Any way whatsoever to take out the SAT?? Freaking out.</p>
