I have an anecdote to share - the university in which I was supposed to study CS before coming to my senses and realizing I know more than the tutors had strict 50/50 gender admission policy. The acceptance was based purely on exam results (only math). So that friend of mine (a girl) is ranked among the top - no surprises there. After she is accepted she decides she prefers to study electronics and according to rules the first girl that was left out gets the place. The problem is there are 18 with one and the same score - so they accept them all. What was curious was that the average acceptance score of the admitted girls was higher than for the boys. So the gender policy actually ended discriminating the girls - fewer were admitted than would have been if gender quotas were lifted. That was across the board in all engineering specialties and a few years in a row.
