SAT superscore?

<p>Hi,
so those colleges that super score SAT, do they ONLY look at our highest scores?
Or do they review all the scores although they focus on the highest ones?
I'm thinking about applying to Columbia, which is the only school in my list that doesn't take the Score Choice..and I wasn't sure if taking SAT for three times or submitting lower scores along with my other scores would hurt my application.</p>
