How can I improve my chances of getting into Columbia as a transfer student?

<p>I have just completed my first year in college and my overall GPA is a 3.8. I attend a public city college (CUNY). I plan on applying after I complete one more semester. I don't really have anything that would distinguish me amongst other applicants. To make matters even worse, my high school grades weren't too hot (2.5 GPA) and neither were my SAT scores (1540). What could I do to make myself a stronger applicant? I have one semester before I apply. Any advice would be greatly appreciated.</p>
