Will the December Free Score Report reach UC's in time?

I took the December 2nd subject test and I have the opportunity to use the free score report. However, collegeboard states that the scores will be sent within 10 days after scores are released, which is December 15th. Will UCs get my scores in their office in time before January 1st?

*** I called the UC Helpline and they said that the wanted the scores in their office by January 1st.

The UC’s state they accept up to the December sitting so if you sent them through the Free score report, they should get there by the deadline.
