I'm Genuinely curious about my odds/how I can improve

Hello! I promise I’m not trying to fish for compliments, I know that my stats are good and I believe that I’m a solid candidate, but I want to go to a top schools like HSYP, Brown (top choice), Amherst etc. which I know are reaches for everybody. What do you all think about my odds, and what can I do to improve my chances (if anything other than writing solid essays can be done)? Anyway, here goes.

ACT: 35
SAT II: Math II 780 Bio E 780

AP: APUSH 4, APGOV 5, Calc AB 5, Calc BC 5, Bio 5, MicroEcon 5. I regularly take my lit classes and physics at a local college to help facilitate my personal schedule. This year in school I’m doing Health, AP Psych, AP Chem, and AP Stat along with writing at the local college.

EC’s: Sport: Member of a national pre-olympic team, nationally ranked, state/regional champion, 2-time national champ.
Boy Scouts: Eagle Scout
Yearbook Editor 3 years
Debate Team
Volunteer Work: Volunteer for local theater, Volunteer Assistant Coach
Science: Independent Research at Penn (summer), Paid independent Research at a Cancer Institute (summer), 2-time ISEF participant, 3rd place Medal Winner, 3 special awards won.

Anyway, once again, I’m not fishing for compliments (I promise), I legitimately want to know if there’s anything that can be done to improve and what my odds are. Thanks!

what’s your GPA?

Class Rank 1 out of about 300, GPA 4.65 (4.0 scale, weighted) 3.97 unweighted

Oh, also, looking to go med in the future.

4.0 scale means that 4.0 is highest possible I think?
if you’re interested in medicine, you definitely need some volunteering related to medical things, like at a local clinic or hospital. (emphasis on this)

Your stats are good, so it depends on your personal statements, EC’s/volunteering stuff, and interviews. and rec letters

are you applying for brown’s 8 year med program?

Yeah, 4.0 is the highest possible unweighted. Thanks! I’m actually hoping to do some shadowing next month (We’ll see). Yeah I’m applying to PLME, but I’m hoping to do econ/premed wherever I end up (If it’s possible of course, PLME and Brown just make it nice and relatively easy)
