It depends on what and how you are being taught. Women are more submissive to authority, so you can put them in any type of class and they're more likely to willingly be brainwashed by whoever is speaking to them. A lot of grades are based around telling the teacher what they subjectively want to hear. Things like math where it's not just subjective brainwashing and regurgitation of whatever the teacher wants to hear seem to be dominated by males though.
