I had a lot of experience with this. I'm not saying that it's all women. But based on my experience the perceiving of the teachers with girls and guys are different. They think girls excel more and that guys don't. They give more extra credits to the girls, even though if we got the recitation answered. Also if we passed and got a high grade, teachers will be skeptical about you on how did you do it, like did you cheat or ask someone abt the answers. what do you think?
