any advice on starting a career as a female correctional officer in a males prison?

I'm a 22 year old woman and my application was just accepted to begin testing for a correctional officer 1 position. If accepted, i would most likely be employed at the maximum security or maryland correctional training center. I've been preparing for my tests so in hopes that i pass, does anyone has any advice or tips i should keep in mind when entering the career? I'm not nervous or anything, i just want to perform my job the best i can. And other people may know things i don't know. So I'm basically trying to be a sponge to absorb other peoples knowledge. Thanks everyone.
