Sending SAT/ACT

Hi,

I just saw UMD requires official SAT/ACT reports, and I still haven’t sent mine in yet. When I send scores, does UMD receive them automatically. I am confused about the whole process. On the College Board website, it says rushed SAT scores will arrive within 1-2 weeks, and on the ACT website it says priority ACT will arrive in 3-4 business days. However, I do not see the option to send priority ACT scores when I try to. Help is greatly appreciated.
