Submitting December ACT scores to UT

I’ve already taken and sent in my SAT scores to the University of Texas at Austin but I’m taking the ACT in December (that was the next testing date available at the time). I know on the website UT states that they will accept scores up to December 31st and that they will deny someone for sending in scores late. Do you think they will still accept it since I already have other scores submitted and since I’m taking the test in December? Also, how effective would it be to pay for the priority delivery report? Thank you!

I’d just send the scores from the time you take the test - they should arrive shortly after you receive them online that way.
