Hello, I will chance for chance

.
I am rising senior...
GPA/Rank: I don't know what it is on the 4.0 scale, but the rank is around 13/~700 or top 2%
SAT: 2240/1490 (will take again in October)
SAT II: Math II 800 Chem 770
AP: 5 on AP World History, AP US History, AP US gov, AP English, AP Calc BC, AP Physics B and 4 on AP Stats and AP Chem (both of which I self-studied). I also self-studied AP Physics C (both parts) and will be getting those scores next month.
Classes: Generally, I always took the most challenging courseload. Also took three courses at the local college (Calc III, Real Analysis, and Complex Analysis).
Senior year I am taking AP French, AP Lit, AP Comparative, AP Chem, and a university higher-level math course.
Volunteer: ~250 hours at local hospital
Extra-Curricular: Science Olympiad (co-captain), Debate Club (co-founder), Math Club, French Honor Society, Model UN
I am also doing research in molecular engineering with a professor of the local university over the summer and will be submitting to Siemens/Intel.
The two things I haven't really done are physician shadowing and medical conferences/summer programs. Do BA/MD programs seriously consider these things or should i just focus on research and SAT? Since the summer has just begun, I was wondering whether I should devote a lot of time over the summer looking for physician shadowing.
I am interested in applying to the following BS/MD's: CUNY/Sophie Davis, SUNY Stony Brook, RPI/Albany Medical, University of Rochester, and Boston University.
