It can go at least two ways, neither of which is favorable to women:
Johnny studies 6 hours and gets a B+ on the big Math test.
Beth studies 18 hours and also gets a B+ on the big Math test (because Beth just isn’t very smart, but she works really hard to achieve equivalency).
Johnny studies 6 hours and gets a B+ on the big Math test.
Beth isn’t really sure how much she studied and isn’t really sure how much Johnny studied, but she only got a B+ on the test and that is just SOOOOO unfair, because she tried really hard and she’s clearly a victim and everyone is out to get her and she clearly deserves an A.
That’s a pretty good analysis. I’m just going by the time I spent as a close associate of the MIT community. The guys were absolute wizbangs—walking, talking geniuses. The gals were what the PC crowd would have called, ‘underrepresented.’ Even of the ones I met, they didn’t compare to the guys.
Male and female brains are just different. There are exceptions in the STEM area, but they are just that—exceptions.
