Do colleges have to see all your SAT scores?

<p>I'm thinking of applying to USC, UCLA, UCSB, and Stanford.
Can I just send them 1 out of my 3 SAT scores or will they see all of them?;O</p>

<p>I don’t know about USC, UCLA, UCSB. But Stanford asks a student to submit all scores. This rule doesn’t apply if you have ACT and sending those are a financial issue for you.</p>

<p>UCs and Stanford require all SAT scores, but I think USC allows Score Choice.</p>

<p>So if I take the ACT does that change anything?
Also I’ve taken 2 SATS. one - 1810. Second - 1870.
Should I take it again in October of senior year? (I’m about to be a senior)
Or should I just take the ACT in September?</p>
