I am in a pretty similar boat as you with a similar UW GPA, but after seeing some of the comments on my chance post, I think I can offer you some advice. Your test scores this far are pretty good and colleges will understand that you have a strong interest in comp sci by the subject tests you have taken. Furthermore your ECs are pretty out-of-the-ordinary so they may be enough to overshadow your GPA. As always, I recommend applying to some safety schools in case, but I do think if you apply to 5 or more of these elite schools, you have a pretty decent chance of getting into at least one. Good luck! I would appreciate it if you could chance me back here: http://talk.collegeconfidential.com/what-my-chances/1995754-chance-me-low-gpa-rank-cornell-rice-wash-u-ucla-etc-p1.html
