<p>Females generally get higher GPAs than males. So if you decrease the male/female gender ratio - one might expect GPAs to increase.</p>
<p>But on the other hand - do relationships improve or decrease average GPAs? Maybe it all averages out. They distract some individuals from their studying. But it could sometimes help some people to study as well. </p>
<p>One could think of MIT - which does gender-based affirmative action. What about that?</p>
