Nice on the quantum mechanics course. You still need to take SAT IIs. What's your favorite EC? I've heard around that passion in a couple instead of barely getting involved is better. Im assuming Model UN? High reach at Princeton (bc its Princeton and your test scores so far...), reach at Cal Tech, U of Cal bc of OOS. Low reach at Carnegie Mellon, U of Chicago, and Cornell.
Idk enough about UVA for instate students to tell you your chances, but I'll go with low reach. I say these are all reaches just because they're the top schools in the nation, and only siemens winners, etc, are matches. So you are a very competitive applicant to all these schools. i suggest a safety or two though, just in case, but I'll guarantee you'll get admitted to one or two of these schools.
Good luck!
If you have nothing better to do, wanna chance me back?
Chance: BU Trustee, BC Presidential, Harvard
