You don't have to wait.
On a related note, does anyone have any knowledge on how long it takes for schools to receive/process these reports
on average? Particularly, when would you expect a university to receive a report if that school was one
of the four free reports chosen when you signed up for the test?
I'm not sure, but I think it's pretty quick... I checked the status of an application about 1 week after my scores were sent and it already displayed "Received".
It may vary from one institution to another, I don't know.
