Why are girls better at the university?

ProfessorAs
I am a new university professor. I noticed girls in general are better at class discussions. doing the required homework, and with analytical reasoning. asked other professors from several universities, mainly men but from both genders, and the vast majority had the same observation.
as a professor, it is my duty to lift the level of my students skills and notably teach pieces of information. therefore my questions is for all but mainly to students. what do you think is the reason? is it only maturity and responsibility? or is there something mental. When you discuss classes with the other sex do you feel they are intellectually Superior/inferior? or you just feel they are more/less active in the studies?
