OP should of course do his or her own research to test hypotheses, including the gender-specific information at LACs. Everything on CC, to be honest, is a guess as to what may happen behind closed doors.
On the “LACs don’t accept by major” point… that does not mean they accept students without keeping in mind institutional priorities re populating their majors and various departments. On a curious anecdotal note, every single one of the female students who got into an Ivy from our fancy prep school seems to have applied as a STEM major; random coincidence or institutional priorities at schools historically failing to attract female science-track applicants? Probably for another thread…
