1) There are too many women in undergrad biology, at least 90% are women. Honestly, I think that stem programs should expand not by poaching dummies from other majors that flunk out. I think that they should aim to steal women from biology into other stem fields and men back into medicine. 2) no mistakes about it, biology is not a soft science. I had to take 3 semesters of physics, calc plus applied calc, stats plus applied stats, four semesters of chem (mandatory minor in chem). My "fun" classes were in algae, fungi, human entomology, and epigenetics. It was a crazy and difficult time. There is no way a program as rigorous as mine could be faked or cheated through. The cheaters flunked by 3rd year. Trust me, there were a lot of privileged minorities who didn't make it past 2-3 years in the program. (one of them was recently forced to return home because of Trumps immigration policies) the medical education system is extremely difficult. If you don't pull your weight you loose everything. I knew a girl who got into the program because her parents were both drs. She had scholarships, every kind of sliver spoon imaginable. The program chewed her up and spit her out because she was weaker than her parents and had no business being a nurse, never mind a dr.
