You might be surprised. My daughter took first year university linear algebra last year and graded assignments and tests were often returned weeks later, in some cases well into the exam preparation period. I told her this was unacceptable and she should complain, but you can imagine why a young, shy first year student might not be able to get over that potential barrier.
Another thing that one might not have considered is the perception of women and math. Of course your daughter might not want to protest against unfair mathematics teaching structures given that her struggle is societally used to represent that all women struggle at math. <relevant xkcd comic here>. I would also hesitate to protest unfair practices in situations where I was a minority because I know anything short of quietly excelling is a negative representation of my entire demographic.
