Submitting SAT/ACT Scores

I am planning on applying to a few University of California (UC) schools next fall, and have taken the ACT three times and the SAT once. Based on the UC test requirements, will I be sending in all SAT AND ACT scores, or can I send in all of my ACT scores or just my SAT score?

If someone who has been through this process before has any insight, that would be especially helpful.

Under current rule, you can choose to send either SAT or ACT. However, by fall, when you will be applying, rules might change, and you need to check then to see if there has been a change. Also, you need send scores to only one UC to which you apply and all others will get them from the one

You can choose to send either all your ACT scores or your SAT score as stated by @drusba. The UC’s will take the highest score from a single sitting. Also as stated by @drusba make sure you check the requirements before applying since there can be changes made.
