Sending Scores

I know I have a lot of these last minute questions but bear with me. When do scores have to reach colleges? Do they have to get to the colleges by their deadlines? Or are they lenient about when it arrives. I know that the common app has a self reporting section, but I want to make sure just in case. I have a lot of January colleges and I just sent scores to some of them. I did look on websites but a lot of them are vague. For instance, Georgia Tech first says that you can self report until the scores arrive but then it says to send scores ASAP to avoid missing a deadline. I was just wondering if anyone had any ideas about what the general policy is for score reports.

I am wondering in particular about CalTech, University of Chicago, UPenn, and Georgia Tech. I think for Univ Chicago they allow you to just self report until the scores arrive but, again, it’s vague. I already talked about Georgia Tech. Not sure about UPenn or Caltech as they are vague too. Caltech, as far as I can see, only talks about a deadline for taking the test but, again, I want to be sure. Does anyone have information about this from prior experience?

I have already sent scores but I can rush ship if I need to (2 days).

I just sent the scores today which is why I’m concerned.

I really need help with this. Does anyone have info?
