<p>What they “want” to see is up to each school. Even those schools that require all your scores sometimes use computer programs to calculate the highest score rather than actually looking at your entire testing history. Nevertheless it is in an applicant’s best interest to put his best for forward whenever he can ie. only submit his/her highest scores when given the chance. The uc system asks for SAT or ACT scores meaning that you can submit either one test or the other, but if you choose to submit the SAT you must submit all SAT1 scores. </p>
