I know it’s a bit too early (I’m only a sophomore, eep!) but if anyone has an idea on schools with fairly strong math/computer science departments– please shoot! Unweighted GPA is somewhere around 3.95, and I’m an international student.
Preferably schools with 30+% acceptance rate, though, and somewhere on the East Coast. Cost isn’t too much of an issue, anything below 50k is fine! So far I’ve got:
NYU (Courant)
UMichigan
Carnegie Mellon
Stony Brook
URochester appears in a Princeton Review sampling, “Great Schools for Mathematics Majors,” and would appear to meet most of your requirements.
@merc81: Thanks! I’ll look into that 
RPI fits your description and has a strong CompSci dept (Math too).
For the full, somewhat eclectic list, you can see #17 here, @VaporeonKid :
Consider the schools to represent a sampling of those that might be good for you. Nonetheless, the list could be helpful for generating further ideas.
Also, consider whether you want a school with “great math and CS” or “great CS and math” (in other words, which of the 2 is main focus). Obviously some schools like CMU will be tops in both, but bear in mind CS at CMU is extremely difficult to get into (CMU’s overall published acceptance rate is ~25% but its CS acceptance rate is around 5-6%–arguably the most competitive CS department in the country or at least on par with MIT/Stanford/Caltech; Math is easier to get into there).
@insanedreamer: By RPI, do you mean Rensselaer Polytechnic Institute? Sorry, I’m not too familiar with the acronyms of schools!
@merc81: Thanks so much for the list – super helpful and insightful (albeit a tad bit unique, as you said)!
RPI, do you mean Rensselaer Polytechnic Institute?

Yes
Also Northeastern
Thanks! I visited Northeastern and loved the campus – nice to know that it has a great math and CS department! @insanedreamer
@VaporeonKid, Will you be applying as an international, i.e., not an American citizen or permanent resident? If yes, then you can’t use overall acceptance rates or net price calculators as guidelines.
If you can afford the difference between $50K and whatever the cost of attendance is (could be +$15K a year) then you will have an advantage over other internationals that are applying for financial aid. But bear in mind that if you don’t apply for aid the first year, your options to do so in subsequent years are extremely limited.
If you need or want financial aid, read each college’s policy toward international students carefully. CMU and Stonybrook, for example, do not offer any aid to international students.
@momrath: Thanks for the insight! And yes, I will be applying as an international student. My parents have mentioned that they don’t expect any FA throughout college, and they are willing to pay full-price (+ attendance costs). I’ll definitely look into all the schools’ international student admissions policies!
If you don’t need financial aid, then don’t apply for it. This will give you a substantial advantage in international admissions. But first be sure your parents fully understand the cost of attendance, including transportation if you live outside the U.S. and projected increases. Private school costs are already well over $50K and in two years will undoubtedly be higher. If you don’t apply for aid in the first year, you may not be eligible for it in later years, so plan conservatively.
@momrath: I understand-- I’ll discuss this with my parents! As far as I know, they have explicitly mentioned they do not need financial help in paying for school, but I’ll ask again to be sure. Thanks for the insight!
If you would like a maximal undergraduate focus for the study of math and computer science, do not overlook liberal arts colleges. Beyond the “gateway” college math class, proof-based linear algebra, you will find that the best of these colleges offer 15+ further mathematics courses within their departments from which to choose.
@merc81: Which liberal arts colleges do you recommend? I’ve looked at Williams (absolutely love it-- but it’s a bit of a reach for me) and Harvey Mudd (don’t like the location, not really a fan of CA)!
If you’re female - Wellesley. Probably best math department of all LACs except Williams (which doesn’t have even near a 30% acceptance rate). CS department is way too easy as is common for LACs, but Wellesley CS grads mostly still seem to end up with decent jobs at top companies, i.e. Apple, Microsoft, Google, various startups (don’t know the job retention rate after 2 years though).
Also I noticed you put down CMU. CS at CMU is definitely a lot harder to get into than other colleges at CMU - definitely a lot harder than 30% acceptance rate.
I am female-- so thank you for the insight! However, I’m not too sure I want to go to an all-female college. @doctorgirl
For math, look into Hamilton, Bowdoin, Haverford, Reed, Carleton and Grinnell. Schools from within this group frequently enroll math majors at ten times the national average for colleges of any type. Then consider the CS offerings at these colleges, which appear to be strong at Hamilton, Haverford (when considered with options at Swarthmore), Grinnell and Carleton and perhaps growing at the other schools:
@VaporeonKid, If your 3.95 UW GPA is on a 4.0 scale, then you could target a few super-selectives, like CMU, Williams, Brown, or any others that interest you as long as you apply to a balanced list of reach, match and safety. Of course you would need to present outstanding scores, extracurriculars, essays and recommendations as well, but there’s no reason to eliminate the reaches just yet.
