I think they'd make a college education something that's only available to women if they could. So far they're having to settle for quotas that make it as difficult as possible for them to be accepted, and rules that make it as easy as possible for them to be expelled before they can graduate.
Given the persistent, bothersome fact that men tend to be more financially successful than women (due to men being more willing to put in longer hours, spend their lives on the road, aggressively go after their goals, and other factors which feminists are loathe to admit), if you can't MAKE women be more successful, well then the only thing to do is cripple the careers of the men.
