By the way, I took the ACT last April and got a 31 composite (32 English, 32 Math, 31 Reading, 30 Science). I'm taking the SAT on Saturday and am really going to try to get a high math score. I took the Math 2 subject test and got a 710, and I got a 5 on the AP Calc AB exam if that stuff matters.
I will also apply to Stanford and Rice as my most selective schools -- will the 28 in math matter a lot there? I believe it won't hurt as much because they are liberal arts universities at their cores. On the commonapp, I will say that I intend to study computer science as my first choice, though.
I also know that Univ. of Washington doesn't admit based on major but it would be nice to be directly admitted as a CS major because I could always switch if I wanted, plus, getting into their CS department as a sophomore is difficult. At UCSD I think they limit enrollment to the CS major, and if I don't get in then I might consider another school where I know I'll be able to study CS and be able to switch if I want.
