We were a very technical field of studies and had only a few woman enlisted. Bringing those few successfully through their time was valued quite high.
Requirements to their work were clearly lower than for us and getting an appointment with the professors was easier for them, too. All in all it was less of an overall-hassle for them.
But yeah, one might say this is some kind of survivorship bias or whatever, I don't care. It's what I perceived and it was also a recurring topic in "mens only"-discussions. So other perceived it that way, too.
