Its really hard to get into.
With more university under your belt, the better your chances.
But even that, good luck getting the country you want.
Just being real, from what PeaceCorps friends have told me.
Plus, once you're there, you're on your own.
You don't have a Peace Corps supervisor or anything like that.
But it'll look great on your resume.
(I myself would consider just traveling on my own accord, but I'm low on dough)
