Applying to UWC

<p>I'm in ninth grade and I'm planning on applying to UWC at some point soon, for grades 11 and 12. For all the UWC alumni out there; is there anything I should know before applying/the possible interview to come? Also I think it should be noted that I'm going to be applying for a scholarship. Last thing before I post this, I want know how much they care about your grades when they consider accepting you. My grades are kind of all over the place. I mean that I have classes that I get C's in, classes I get B's in, and a couple of classes I have A's in (or probably will soon). I think I heard somewhere that they go mostly off how you are in your interview, but I really don't know.</p>
