My daughter, was told by her science teacher, that a b grade was unrealistic, she had an a for her isa, and a c in her mock. My son had an a for his isa, and a 'd' for his mock, was told he just needed to revise.
He got a 'b', my daughter hasn't taken hers yet, but has stopped trying. The point is that everyday sexism is alive in my local school.
I did stand up for her by the way, i said you underestimate her. But his face spoke volumes.
