I gave a presentation on my previous work today to the graduate art class I got myself into. When I was taking questions, the professor asked me, "how do you do in your mechanical engineering classes?"
I wasn't really sure what to make of that. When he repeated himself, I said I do well.
I ended up later arguing with a (male, engineer) friend who thinks females are genetically less likely to be good engineers, though he says it doesn't apply to me.
