If I remove psychology, then Carleton is 1st at 40%, Hamilton is 2nd at 36%. Other question is should be adding in Natural Resources and Conservation (aka Environmental Science)?
In my opinion natural resources and conservation is distinct from environmental sciences and usually found at larger state universities. They are sciences but not enviro science.
edited to add: Where has she visited or are you trying to set up first visits now?
Excellent suggestion by @merc81 to look at the physical science building. Adding on to that, perhaps have her reach out to some profs in her area of interest. All excellent choices, I think school vibe could be the tie breaker.
What was her #1 choice? Perhaps evaluate what she liked about that one and find the closest match among her plethora of outstanding choices.
I’m not trying to downplay her disappointment- it does sting to get a bunch of turn downs on the same day, but you started your question with the word Unfortunately. That’s a glass half empty term when she really has a glass almost filled to the brim.
Is your athlete daughter leaning anywhere?
This needed to be said.
@wisteria100, no offense taken as the disappointment was hers, which is completely natural for an 18-year old kid. Yes, she’s lucky to have the amazing choices she has, and over the next couple of days she will feel that way too. Her twin Is leaning towards two NESCAC schools that she has spent a lot of time with the coaches - both are wonderful choices.
Aside from the specific academics what type of community is she looking for? Does she care if a campus tends to be more sporty/jockish or if it has Greek life or if the students are a bit more quirky/nerdish? Does she want a more intense or a more laid back academic environment?
Personally I too would find it difficult to choose among her schools- they are all excellent options! If she does not care that she is not in the mountains, and if she is looking for higher intensity academics with a friendly but quirky student body, I personally think Carleton is a clear winner. Just hands down hard to beat the fact that the academics are outstanding, it is in a lovely small town yet still so close to the Twin Cities (not regionally isolated) AND the student body is exceptionally friendly and down to earth. From everything I hear Carleton is a very happy place and its students have tremendous opportunity post grad.
I would use caution when considering the waitlist schools as well. The fact that they waitlisted her does not mean that they are better options for her chosen field. Her seemingly top two choices, Hamilton and Carleton, are fantastic institutions. They may actually be better, and certainly appear at the very least to be comparable, choices for neuroscience.
@Apple23, agree. Based on her research DD is felling that Hamilton may be the best overall fit, even though Carleton arguably has the strongest STEM program. Another consideration is potentially wanting to be at a different school than her twin so that she can grow on her own - that will play into the equation as well.
What does her gut say? Has she joined any of the accepted student Facebook groups?
I wouldn’t judge by accepted student Facebook groups based on my family’s experience. They tend to attract a certain type of user which may or may not reflect the student body as a whole. Typically, discussions are dominated by a few dozen people who may or may not actually matriculate.
In fact, if you took one of my kids’ advice, you’d completely stay clear of them. 
Visits or overnights scheduled? That would be another way for her to get a gut feeling.
Hasn’t been to Carleton yet since it’s far away - planning to go to accepted students day; been to Hamilton and all of the NE schools at least once as they are drivable for us.
@wisteria100, the science building at Hamilton is a beautiful facility; best she can tell the science quad at Carleton is going to be under renovation for the next 3 years so while it’s going to be great in 2020 that’s a negative for now - is this a correct assumption?
I’ll put in a plug for Bates.
Bates has a full neuroscience department. While some schools offer neuroscience, at most places (Carleton, Colby, Colgate) it’s a concentration or minor located within the bio or psych department. At Bates it’s a full-blown major.
Bates’s digital and computational science program is young, which might at first glance seem a disadvantage, but in reality could be a real advantage in that the program isn’t bogged down with a lot of old tenures profs teaching nothing but Fortran and Cobal. It’s meant to be a truly interdisciplinary program. There will be a major starting in the class of 2018 (meaning your daughter could declare as a DCS major if she chose to) but the classes are also available to students across all disciplines.
Here’s a explanation of the new program and how Bates sees it going forward.

I’d also add that from your description of your daughter I think she’d be very comfortable at Bates, although I don’t think she’d be uncomfortable at any of the schools.
@Sue22, thx and I’ll make sure she knows about the Comp Sci program - pretty sure she already does as she did alot of research on her choices. While she knows that she wants to pursue Neuroscience for now, a broad LAC palate is important to her as she’s just getting started on the next part of her journey.
I think the hardest part is that she’s ended up with a bunch of great choices, Bates included. So now she just needs to pick one acceptance that she feels is the best fit, and then throw a waitlist or two into the mix if it feels the same.
Bates seems to strongly reinforce their neuroscience offerings with related classes in their psychology department. In this way, Bates may be the standard bearer that the other choices may need to approximate.
Here are the plans for Carleton and the science buildings: https://apps.carleton.edu/campus/doc/Sci_Plan_Const/
It sounds like Carleton is putting some good resources into the physical plant in the sciences but you may want to ask questions about how the construction will affect students over the next few years. It looks like the bulk of the construction will be completed in the summer of 2019, when the OP’s daughter is going into her junior year.
@Sue22, agree as it could easily slip into 2020, so not certain what kind of experience you have with scaffolding everywhere - definitely not ideal timing for a Fall 2017 student.
While I’m not picking for her, the 200,000 SF Taylor Science Center at Hamilton is a wonderful facility.
