Too Late to Send Test Scores for Merit Scholarship Deadline?

I already sent in SAT/ACT scores by the Dec 1st deadline but I improved my score for the ACT Dec test. Will they accept it if I sent it today?

From past years, the chances seem good that all decisions on who will be invited to interview for the top scholarships have already been made by this time. Invitations for interviews (along with acceptances to this subset of admits) go in the mail in about 3 weeks, and they need a lot of time to process those accepted packets, etc. If your Dec ACT scores arrived before they screened your application, you could be good. But chances are, it was too late for merit consideration. OTOH, those scores will be used for admissions decisions. Good luck.
