Jan SAT scores confusion

<p>The January SAT scores were received by Columbia on February 14. I have a doubt that my friend already sent in December 2013 scores before. As Columbia accepts Jan scores too I want to ask whether
Columbia looks a second time on the app after Jan scores arrive?</p>

<p>It is just because that guy has 2000 in Dec but 2200 in Jan.</p>

<p>I am asking this question on behalf of a friend.</p>
