Stereotypes given by people have brought the confidence level down. Women start to believe that they're meant to be dumb and that's how people want them. So they don't try. But with the proper education and encouragement, people can meet a different expectation. At my school, the girls have higher scores than the boys. I'm not saying I'm against also encouraging boys, I'm just saying it's possible for women to meet a level of intelligence that can also be represented by males.
