I just sent my scores today for the regular deadline universities which are mostly Jan 1st, and I DID NOT USE rush score reporting. Will my scores reach on time? I am kind of worried right now. Please anyone help!
Probably no issue since most of those colleges accept scores that arrive after the applicaiton deadline, and thus you are likley safe even if CB does not send them by the app deadline. Even with those that state they want scores in their hands by the app deadline, you are probably safe because they will likely still accept them if they come quickly after.
As to whether they will be sent by the app deadline, the answer is maybe, maybe not. Scores, both rush and regular, are sent these days by College Board putting them in an online account that a college has with CB and thus delivery officially occurs the same time as the score is sent, but CB may take more than a few business days to send them; note the same would be true of rushed scores which these days may or may not increase the sending speed from regular, and if it does, it is often no more than a day quicker.
Thank you so much @drusba for your detailed response. I overheard that it may take 2 weeks to reach the scores to my universities. I hope the Adcoms will be fine if my score gets there around Jan 11th since I have already self-reported on common app as well.
