I agree with others that St. Mary’s might be a good option.
Have you considered Brandeis? It’s got a large Jewish population with solid programs in the sciences, opportunities for lab research, and it offers merit. Plus the Boston area has no shortage of medical facilities.
You might want to check out some of the Colleges that Change Lives schools (CTCL). Many of them offer merit aid and she would be in the top 25%ile of applicants (necessary if merit aid is sought –– top 10% would be better still).
If she’s open to Women’s colleges (you mentioned Bryn Mawr so I presume she is), some of them are generous with merit (e.g., Bryn Mawr, Mt. Holyoke, Scripps). Here’s a CC thread on that topic:
Also, given that her HS GPA is good and she’s taken a challenging curriculum and has strong EC, taken dual enrollment, etc., you might want to think about NOT submitting any standardized test scores if they are under 1,500. A 1,400 SAT score might do her more harm than good in terms of admissions and especially in terms of obtaining merit. Many –– if not most –– schools (including the most competitive) will be test-optional or test-blind this year because of COVID (and many have decided to go that route permanently). You might want to take advantage of that and have her apply with her strong HS record, good essays, and solid teacher and counselor recs.
(I think you threw a few people off in the beginning when you mentioned a 3.5 projected college GPA in science classes and a need for hand-holding, it sounded like you were talking about her HS record). Good that you clarified.
