How Do I Fare?

I will beginning my junior year of high school this year. While I plan to apply to the top ~20ish schools for premed, I’ve been feeling a little nervous.

I’ve maintained a 4.0 GPA until now and feel I can expect a 3.95 or 4.0 by the time I graduate.

So far, I’ve taken (for AP):

2015

AB Calculus (4)

2016

AP US History (5)
AP Psychology (5)
AP Biology (4)
BC Calculus (3) - AB Subscore (5) <<<< (I was expecting a 4, and was really disappointed knowing how high the 5 rate is.)
Physics 1 (3) <<<< (Honestly, I’m happy about this one. While my school offers the class, we technically didn’t have a teacher. I wasn’t even expecting to pass given my circumstances, so that one doesn’t bother me.)

SAT Subject:
Bio (710)
U.S. History (650)

Yes, I will take a Math II. I plan to take it enough times to achieve a score of above at least 720.

Is it worth self-studying/brushing up on the material for BC Calc next year while I take other classes in order to improve the score, or is this just one score and I shouldn’t be concerned.

Future classes:

11th Grade (2017):
AP Stats (4-5?)
AP Chem/IB SL (4?)
IB History/AP World (5?)
AP Lit (4-5?)/IB English HL 1

12th Grade (2018) Obviously I’ll get these scores after I apply and so they won’t “matter”, but they’ll of course be on my transcript
IB English HL 2
IB French SL 2
IB Bio HL 2
IB Math HL 2
AP US Gov

As for standardized testing, I took the PSAT as a sophomore and got a 1360 (out of 1520).
As for an ACT score, let’s assume I’ll get a 32-34.
And SAT, I’m unsure where I’ll place, honestly. Is 1400 a safe bet given PSAT + actual big-time studying in the future?

As for EC’s (+Projections):
-3 years of Peer Court (80+ volunteer hours on a peer panel for juvenile offenders)
-I’ve been playing piano competitively for ~9 years now, with at least two duets, solos, and one concerto/yr in my city’s university festival competition. Hope that counts?
-2-maybe 3 years of varsity tennis
-I started the Feminism Club at my school where we do annual donation drives to the Road Home and have weekly meetings.
-4 years of staff writing for the school newspaper
-3 years of French club
-NHS?

Sob stories (because let’s be honest here, there will be an essay of how I’ve “overcome challenges” or some crap like that).
Growing up a gay teen in a conservative household in Utah? Who knows if that’s an essay that writes well.

Long story short:
-Can I hope for admission to an Ivy League or any school in the top 20?
-Should I try to retake BC calc, or will one or two low AP scores not matter much, given a good grade in the class/the rigor of my coursework?
-How do I avoid being burned alive by all of this? (And how do those perfect scoring, 16 AP-class-taking ubermenschen still breathe?)

Thank you for reading through this mess. It means a lot!

O.K. you are impressive, but ima go down the line bluntly here. (Hope no offense taken, trying to help)
Good GPA and AP test scores
Bad SAT II scores, this will limit you extensively.
PSAT doesn’t matter at all.
I can’t actually grade your chances without actual scores, even with them its mostly luck but w/o = impossible
Bad bad bad ec’s
The essay would work IF you got a AC that wasn’t against that type of thing, I’m personally not, but there is a chance you get someone who will look down on you because of it, so be careful
And just for the point, you shouldn’t just take IB or AP classes for college admissions, Ivy league Deans have specifically said as long as its challenging for the student 6+ AP classes in High School, we level them all out as equally rigorous
