Chance me? What are my chances of getting into Caltech, Brown, Harvey Mudd?

(Going into 11th grade, planning to take 6 honors/higher level classes)

(If it matters) Race/gender: Indian male

Intended major: Physics

Received A’s in all my STEM classes except physics honors where I got a B+

Unweighted GPA for sophomore year: 3.78

of honors classes: 5 (AP US History, Multivariable Calc, Chem Honors, Physics Honors, standard English, Spanish 3 honors)

Unweighted GPA for freshman year: 3.82

of honors classes: 1 (Standard history, Standard english, Biology, Spanish 2, Differential equations)

APs: 5 on AP calc AB (8th grade), 5 on AP calc BC (9th grade, self studied), 5 on APUSH (10th grade), 5 on AP physics C Mechanics (10th grade, self studied), 5 on AP physics C Electricity/Magnetism (10th grade, self studied)

Received AP Scholar with Distinction

SAT: 2230, 800 on SAT math II, 690 on SAT US History

94.5 on AMC 12B, 2015
Participated in F=ma exam, score unknown
Part of Robotics/Engineering club at my school
Part of the Cross Country/Track teams at my school, not varsity
Part of school orchestra and outside orchestra (violin II)
I do volunteering as well
In 9th grade I did an internship in computational chemistry that included a final presentation, I’m going to start a physics internship this year

What would be my chances of getting into Caltech, Brown or Harvey Mudd (extrapolating these stats to my 11th grade year)? What are some realistic universities I can look at (that have good physics/STEM programs)?

You are very advanced in Math. I can’t recall reading about another sophmore who has taken Multivariable Calc, i’m sure it happens but it’s not very common. I think you are pretty competitive, i would recommend focusing on your EC’s particularly the math and science ECs. Internships at NASA, that type of thing. To be honest, looking at your background I would have thought Stanford, MIT, Harvey Mudd, Franklin W. Olin not Brown. Your unweighted GPA is lower than ideal for Brown and many other very top colleges but your course rigor is likely to be off the charts by the time you finish with high school. Ideally when applying to schools like Brown you have A’s not only in your chosen field of study but A’s across the board

As I mentioned in your other thread, your best bet is building on your superb math credentials and going for colleges that will value brilliance in subject area over lack of balance in other areas. MIT, Caltech and Harvey Mudd are all good candidates for such schools.
