Can you share your experience with single-sex education?

I’m writing a research paper about single-sex education. It’s mainly about coed schools that offer single-sex classes in certain subjects. I’m not looking for you guys to to my research for me, but I am interested in first-hand (or second-hand, if it pertains to your kiddos) experience with this.

What subjects were offered/did you take? What was your experience? Was it beneficial, and if so, why or why not?

Thanks!
