You are a 4.0 student with a 35 ACT - those stats make you a competitive applicant at every school in those two categories. If your ECs, recs and essays are also strong, that makes you a competitive applicant all-around.
Most of the top schools are reaches for everyone: the Ivies, Stanford, Caltech, UChicago, maybe Duke and Northwestern, and the very top LACs. I think Emory is a low reach/high match for you, though. Rice would be a low reach probably.
woogzmama’s list is good. To it I would add:
Grinnell
Haverford
Brown
I realize none of these are matches, but they are all intellectually rigorous, very non-preppy, and have very little (if any) Greek life.
I’m afraid that all schools - even those listed above - have a grand mixture of kids, and that includes preppy students and/or those just wanting the piece of paper to frame and hang on a wall. Most schools also have Greek life.
The good news is, you will almost certainly be able to find and engage people who are more like you, because they are part of that mix also.
I would suggest some of the good state schools for matches. You will find incredibly vigorous work if you seek it, plenty of people like you to hang out with; and unlike on a really small campus, you can “hide from”/avoid things you wish to avoid: Greek clubs, preppy kids, etc.
Granted, your 100-level lectures will be large at the state schools; but if they are like UW-Madison, those survey courses will be accompanied almost invariably by a weekly discussion with about 10-20 students, as well as a weekly lab in the science courses. I imagine other state schools also do this to help make teaching more personal in the larger 100-level classes. As you get into your major-related courses, class sizes become quite a bit smaller.
So what are some good state schools that would be matches (low, med, or high…) for you as an OOS applicant?
- UVA
- U Michigan
- UC system (Berkeley and UCLA are tops)
- UNC-Chapel Hill
- UW-Madison
- U Washington
- U Illinois
- Georgia Tech
- UT-Austin
- U Minnesota
- Penn State
- U Maryland
…are some of the best. All are strong in many programs, both in the STEM fields and in the soft sciences/humanities.
Some additional private universities that would be matches for you include schools like BU, Northeastern, Tulane, Wake Forest, Case Western, and U Rochester. BU, Case and Northeastern are quite large schools that probably behave quite a bit like the state schools I mentioned.
