Improvement count for anything?

<p>Okay so I'm a sophomore at a public high school (for what it's worth, a good high school, so hopefully that'll help me lol). It only recently struck me that I want to go to a good college and what that involves. Kinda late, I know, but what can I say. Not that I've done /terribly/ so far - I don't think I've gotten a C yet, but I've definitely been A and B, a few honors, yadaya. No extracurriculars to speak of. My GPA weighted is about 3.9, but my unweighted hovers around a depressing 3.5. However, next year I'm actually going to start working in my classes! So hopefully I'll get all As. I will also:</p>

<p>-be president and founder of the Amnesty International Club (and we will do stuff that's worthwhile)
-be in the Academy of International Studies
-be president and founder of the Film Club (haha, I'm not expecting that to help much)
-be on the school newspaper (possibly an editor)
-be a part of our class council
-/try out/ for the play (no guarantee I'll get in, lol)
-take 2 AP and 4 honors classes </p>

<p>I took the PSAT this year and got 750 or so for verbal, low 600s for math (there was no writing), but I hadn't even learned some of the math stuff yet and I wasn't taking it too seriously, so hopefully I'll do significantly better on the real thing. What should I do for "oomph"? What colleges should I be looking at (I REALLY want to go to California, but I'm an out-of-stater D=)? And if I have a 4.0 junior and senior year with a 3.5 freshman/sophomore will I still look okay? If you actually read or skimmed all this, thank you so much!</p>

<p>The general consensus here is that getting good grades all through high school is best, but upward trends are also highly looked upon.</p>

<p>you took the PSAT without writing? how did you do that?</p>
