Should I retake the SAT?

<p>So far I have take then SAT 3 times. Superscored is a 2120 with 780 W, 640 CR and 700 M. I'll be applying to ivies/baby ivies (Columbia, Williams, etc.) and I wanted to know if my scores would be sufficient. I know my CR has to go up, and I really want it to, but the only time I can take the SAT would be january. I have to take subject tests in December. I'm worried that taking the SAT 4 times will reflect poorly on me. I think I can go up in the math section, because on practices tests I've been getting 760s consistently. I don't know about the cr section, it tends to screw me over. Please advise.</p>
