So it turns out I didn’t send my scores into basically all my schools like I thought I did and their applications are all due in early January, most around January 1. 
So I panicked and sent all of my scores using rush just last night. I honestly don’t know how rush service works and if schools will even accept it because I’ve heard that some of the schools I’m applying to do not like it. For example, Columbia says don’t use rush on their website. But I don’t see any other way around this?? What should I do?..
You did not need to rush because for most schools including Columbia, the scores can arrive after the early Jan application deadline (in fact, Columbia and many others even take Jan test scores). Also, even if you sent a rush order last night, that does not assure it will be sent before a Jan 1 application deadline.
Until 3 years ago, rush delivery consisted of College Board sending a piece of paper by mail to a college with your test scores. Many colleges had a policy against rushed scores as a result, because they wanted the usual SAT report via electronic delivery. CB no longer sends anything by mail but instead sends rush scores electronically just like regular scores. Many colleges still say you should not rush scores, but many do so today because they know it is mostly a waste of money since it will result at most in sending the scores a day or so quicker than regular delivery and possinbly not any quicker at all because the college may have a designated weekly date that it wants scores sent, rather than daily, and thus the rush scores just get sent the same time as the scores ordered regular delivery. As the result of how rush scores are now sent, colleges do accept them since they receive the same thing as regular scores.
Ohhhhh! Thank you so much. Ahhh ;A; if I had known earlier, I wouldn’t have spent the the money on them ;A;
