Can I use my December SAT for applications ?

I’m planning to register for the SAT on December 2 this year, but will I be able to use it for my application if I got higher than my former score of 1020 ( I know it’s a bit bad ). I’m planning to apply to couple of the CSUs

check with the school on whether you can use the Dec test date

All the Cal states will accept the December SAT scores except San Diego State, San Jose State and San Luis Obispo. These three schools only take up to the November sittings.
