This suggests to me that Brandeis would be a better match than Tulane. I also have a close friend with a D at Brandeis who is extremely happy with her experience so far (she is a second sophomore). Proximity to Boston for internships and culture/entertainment is a huge plus. Travel should also be considered. It’s not a difficult flight to New Orleans but flights could become fairly pricey in the near future. And they’re often more expensive around the times students tend to fly for holidays.
Brandeis also provides the somewhat unusual combination of a LAC size school with top notch research facilities if your DS is STEM oriented.
Good luck!
