there's a few things i want to point out that are more worth noting.
1) the reality is that academic success has almost no utility in a capitalist economy. capitalism simply does not reward education levels. the business people don't give a fuck. to succeed in a capitalist economy, you need good people skills, not a good education. that is why your bosses in life will always be C student brotards, whether you're a high intellect boy or girl, unless you're also good at being a slut. men get further in life with their social skills than their book learning, and women get further in life by being sluts than by being scholars. that's how capitalism works. your female boss probably did suck somebody's cock to get her job, and it's a coin toss as to whether she did well in school or not. that won't matter, unless she has nice tits.
2) if there's a gender problem in the schools, it's not a reflection of the curriculum, but a reflection of the teaching staff. almost all primary school teachers are women. have you ever talked to any of them? anybody that's spent much time talking to female school teachers will instantly realize that they themselves are the reason the girls get better marks - it's favouritism, and the young boys know that. if you ask the kids, they won't tell you they need more hands on learning, they'll you their teacher is a rad fem sexist bitch that isn't giving them a fair chance.
a better solution is more standardized testing. your marks in school should not be a reflection of your teacher's opinion. your teacher's opinion shouldn't fucking matter - your teacher should be forced to give you an A if you ace the test, whether she hates you or not. testing should be objective and empirical, not subjective and emotional. we have made the testing too subjective and in the process rewarded too much power to a gender bias that reveals itself clearly in the subjective grading criteria. that needs to be reversed.
you will notice the marks balance out if you take away the subjective bias underlying the issue, and the fact that the teachers are the problem, not the kids, will reveal itself through proper empirical analysis.
