<p>Your current SAT scores and your earlier ACT are about equal according to this chart: <a href="http://www.spartanburg6.k12.sc.us/dhs/Guidance%20website/SAT-ACT%20Conversion%20chart.html%5B/url%5D">http://www.spartanburg6.k12.sc.us/dhs/Guidance%20website/SAT-ACT%20Conversion%20chart.html</a>.</p>
<p>If you re-take the ACT, that might be higher. In your case, with your background, I think you can send either or both. In my own opinion, your SATs are strong for candidates of your background, as NSM said, and could be good enough for even the most selective schools. Doesn't mean they WILL be, but could be.</p>
<p>Whether you should apply to Stanford and Columbia depends on how much you want to major in business. Is that important to you, or do you think you might be just as content in a different major?</p>
