In 4th grade, I got a C in math. During my teacher student grade review meeting, my male teacher told me "it's okay, girls don't do as well at math as boys." Yeah, so there's this as a reason. I definitely wasn't a good student until high school. I definitely had a bad teacher who gave me an excuse for YEARS to accept bad results in math. My mother still bitches about that guy to this day. I suspect I have a slight learning disorder that affected my ability to process numbers. I mix 6/9s. 7/9s when transcribing numbers. Made homework difficult. Once I got to the point where letters started replacing numbers in homework, I went from a C student to an A student in math and was competing for the top grade in my math classes. Once I learned that I could do the work, I did the work and excelled. I suspect that this type of bias affected more girls than just me, and these discouraged girls affected US scores.
