My SAT got cancelled and the make up is late

So my SAT got cancelled due to weather issues and the make up was supposed to be set to the 7th, but for some reason it is now set to the 21st. The colleges I want need them though, if I take it the 21st, they won’t get them until about the 10th. That’s a huge problem. I have two SAT IIs already sent, Math I and History. I wanted to take Math II and Bio and send those out too. How big of a problem is this?

Let the school(s) know, but understand that they have many thousands of applicants and a tightly constrained, time-phased process underway, which is necessary to meet their (perhaps) late-March decision deadline. Unquestionably, however, you’re not the only applicant adversely impacted by this/these schedule changes.

Does this affect all those who were snowed out by the original January SAT?
