University of Washington: HCI (Human computer interaction) program

<p>I am studying computer science in a New York state college. My GPA are less than 3.0, but i am still working on it.
Univ of washington HCI program does not require GRE score. it also didn't say GPA requirements, but i guess 3.0 is the minimum.
My question is what i can do right now to improve my chances to get in UW or any other HCI graduate programs except keep working on my GPA . .</p>
