ib612,
First of all, thanks for your help in my thread. You've made me done some serious thinking and I really appreciate it!
As for you, I think your academics are fine. Considering your GPA, test scores, and AP classes, here's what I think:
UC Davis/San Diego/Santa Barbara - You're in.
UC Berkeley - Reach.
Stanford - Reach, as for anybody.
For those two reach schools, I would recommend explaining your extracurriculars VERY WELL on your application. Emphasize what you've done in the library and talk about what you started (colleges love students that founded something new!).
If you are applying to Stanford, write STELLAR essays and develop a strong relationship with your teachers and counselors for PERFECT recommendations, and list your awards/honors and employment.
Lastly, you might want to look at Pomona or other liberal arts schools in Cali.
Hope for me at HYPS? (I'll chance you back!)
