December ACT Help for UCS and USC

I am applying to a couple of UCs and USC as well. I was just wondering if taking the ACT with writing on December 9 would make it in on time to be reviewed. As well as if I take the ACT in December should I post my previous ACT score to be sure that there is something there just in case my scores do not reach them on time. Thank you in advance.

On the UC website, it states that they will accept up to the December sitting.

Submission deadline

Freshman applicants for fall 2018 must arrange to have official score reports sent to us by December 2017. If you plan to take an exam in December, indicate the planned test date on your admission application.

And don’t worry - if you report your scores to one campus, they will be shared with every campus to which you’ve applied.
