i am planning on majoring in math and I was wondering which school would allow me to get the best education out of these three options?
Brown is the best out of these three. The other two are excellent but Brown is far more prestigious (if that’s what you r looking for).
^Enough with “prestige”… I really wish CC would ban that word.
@SternBusiness I do find myself leaning towards Brown…
@harvardandberkeley Thats why I said “if thats what your looking for”. Brown is the best school out of the three anyway. That is the obvious. Just giving my opinion.
Have you talked to the math department? Asked professors about research opportunities, or about what students do after graduation? Looked at course catalogs? Talked to undergrads at all three schools to get their impressions of the department? What’s the percentage of women among the undergrad majors? If it’s low, you might want to gently probe to find out why.
All three schools are excellent. Brown’s Ivy connection means some folks will automatically say it’s the best. Barnard folks will argue that its connection with Columbia means that it has that same name recognition. I have a graduating senior at Tufts who’s received a stellar education. If your research shows that all three will give you the same grounding and opportunities in math, choose whatever fits you best. Congratulations on having these wonderful choices!
@harvardandberkeley Kinda ironic your name is harvardandberkeley and you have issues with the word “prestige” being mentioned lol
As far as the OP is concerned, you simply can’t go wrong with an Ivy 
Slithey Tove’s suggestions are spot on as far as going more in-depth than a simple knee-jerk decision based on the shallow gauge of “prestige”. Obviously that’s why the OP posed the question here, right? She clearly knows that all 3 are prestigious schools. Only she can decide if the slight differences between the 3 schools as far as prestige goes—and let’s not kid ourselves that the differences aren’t slight; we’re talking about top 30 schools; no steep separations that would cause one to say “far more” or “no brainer” or “obviously”—are important to her.
The default “It’s an Ivy, so it must be better” attitude doesn’t really help, and isn’t really quantifiable in the real world.
And my D is a sophomore at Tufts in science, also getting a stellar education with research/ fellowship opportunities. Her good friend is a strong Math major and is VERY challenged (but in a manageable way), according to D.
Good luck! Three phenomenal schools!
^^ I imagine that @harvardandberkeley has a connection to both Harvard and Berkeley. Many CC posters have usernames that correspond to their collegiate affiliations. I’m not sure why that would make his/her opinions on prestige predictable – though they were perhaps somewhat randomly interjected in this thread.
I second Slithey Tove’s suggestions, and here are a few of my own. Try to find students in each university who are majoring in math or the major you intend, and ask for their comments, in particular, women students’ perspectives on how women are treated within the department. You might want to visit all three campuses to get a feel for the surroundings, sit in on classes, where you will meet students you could talk to. If you have been accepted to all three, you might consider contacting each of the deans of admission for each college and pose the question to them - tell them you’ve been accepted to these three colleges, and ask ‘Why should I choose your college?’ and see what s/he has to say. Good luck!
