<p>If you designate USC now, those scores go out to the universities right away - as soon as you see them online (if not a tiny bit before). If you wait to see them, you add a week or more to the amount of time it takes for them to be sent to USC. Your scores would likely not arrive until January, and I am certain that would be too late for scholarship consideration. They would still be fine for regular admissions deadlines.</p>
<p>Remember, USC superscores the SAT and only uses your highest scores. They also prefer you do not use score choice, so there really is no reason to wait to see the scores. Just send 'em and forget about it until Spring.</p>
