If you were sentenced to a 3-year prison sentence, how do you think you would fare

For me it would be about survival I have never been in prison, but I am familiar with the system it's not a joking matter I don't know about any other state, but for the state of NC anything up to a year maybe 2 its county jail anything above that and it state prison Im not trying to sound like a know-it all just saying its about survival and always watching yourself
