How many times should we take the SAT?

<p>I'm wondering how many SAT's we should take cause I heard some colleges like the UC's factor that into their decision, but some private colleges don't consider this?... well if it does matter then how many do you think I should take? I've taken 3 so far (1720,1810,2000), do you think I should take another one and go for a 2150? btw for the 2000: math 800,CR 600, writing 600.</p>
