SAT December Scores

<p>I have taken the March and October SAT tests but haven't sent them in yet. I am applying to UCs (deadline Nov. 30 ) and I wasn't completely happy with my reading scores, so I'm going to take it again at the December test date.
Do UCs accept December test scores?
Can I send in all my scores with the December test date or should I send the March and October ones now and the December ones separately?
Also, do i have to rush/priority deliver December's SAT scores?</p>
