In UC schools, do we submit the best of the SAT scores overall in each subject?

For example, the first time I took the test I scored a 670 in the math section, but the second time, I got a 720. My other two scores (reading and writing), however, were higher the first time I took the test. Does that mean I have to submit the scores as a set, like together since they were recieved from the same date? Or can I put the highest I scored in each subject overall?|||Nope all the scores have to be from one sitting meaning in a set.
