What's here to worry about?
I got exactly the same result. We did similar tests in high school during biology classes, so this test's results came as no surprise to me. ;)

67% female 33% male

^^Exactly the same!

87% Female, 13% Male

Good enough, considering it's just some silly quiz.

I like that is says "You have the brain of a girly girl
Which isn't a bad thing at all"
Contrary to what so many believe.
Sexism is bad, even if you're a feminist.

80% Female, 20% male. I think thats a good thing.
