Chance me 4 Stanford?

Some of you may have noticed my many threads regarding acceptance to Stanford…I apologize for that.
I’m a junior, not a senior, by the way. So stats are subject to change. See my questions at the end.

Extracurriculars:
Weightlifter (not particularly good, though)
Running an actual business (I file my taxes with the IRS and all) that sells cosmetics/skin care products online.
Philosophy Club
President of National Math Honor Society.
Doing a 2-year laboratory research project on Investigating Aspirin-Loaded pHEMA-VP Hydrogel Nanoparticles as a Novel Pulmonary Adenocarcinoma Therapeutic.

Not …much else. RIP…

Current SAT: 1420 (predicted 1520 by senior year)
Math: 770
Reading/Writing: 650
Predicted Junior Year Weighted GPA: 4.31
Predicted Class Rank: 6%
PSAT: IDK

Competitions:
None yet, I will apply/attempt to do RSEF/ISEF this year.
I will apply to the Coca-Cola scholarship thing, maybe Siemens.
Trying to be a TED/TEDx speaker.
I may apply to the Google Science Fair this year, too.

Internships:
Janelia/HHMI Medical Center Internship
I may do the GMU ASSIP Lab Internship…

My questions:

  1. I go to a magnet school for math and science, and my science grades are mostly Bs…OOPS. But my passion is health/dermatology/science… so what are admissions officers going to think about that?
  2. Is it better to be well-rounded or angular in (a) field(s)? I don’t have various extracurricular activities, but I have a few in one field (health/dermatology/science).
  3. What are some common misconceptions about applying to Stanford, and what is one (not-obvious) theme Stanford students have?

“my science grades are mostly Bs”

According to the Stanford Daily, the acceptance rate for 2017 has fallen to 4.65% (down from 4.8% last year). Most students with straight A’s are turned down. Your science grades are mostly B’s.

Apply if you want to. Focus on other schools.
