Retake SAT as College sophomore?

<p>I want to apply to very selective schools, my GPA is high enough (3.958) but my SAT is on the lower side (old sat 1320), I took the SAT only once during high school when I put NO effort whatsoever in scholastics. Im pretty confident that if I took it now I would do much better, but I do know part of this will be attributable to being older than the average test taker. What do you guys think of retaking the SAT at this point of my education??</p>
