Yes, 3.7UW/4.2W is a lot more favorable than 3.4/3.7. And if your rank is high, all the better. Even a 4.0 weighted wouldn’t make you a slam-dunk for Tufts, especially coming from MA (as colleges with a national reputation are trying not to take too high a percentage of local students, yet they attract a lot of local applicants)… but at least you’re not applying with below-median stats, which tends to make the odds pretty low without a hook. Also, these stats make acceptance to UMass Amherst a much safer bet (although you might still keep Lowell in the mix, as there’s some good scholarship money to be had there and it’s increasingly respected as a STEM school).
I still say, give the women’s colleges a chance to win you over. The aid is generous, the admissions odds higher than at mixed-gender schools with comparable reputations, and the “ED bump” is significant at many of them. Plus, you’d be hard-pressed to find a more affirming environment for an LGBTQ+ woman. Smith has its own observatory and very strong STEM, in addition to cross-registration with UMass Amherst and the other consortium schools. https://www.fivecolleges.edu/academics/astronomy As I suggested in my earlier post, run the Net Price Calculators for Smith, Mount Holyoke, and UMass Amherst - do the LAC’s look like a better deal than the state flagship, for your financial profile?
