What is a small, private Catholic college like?

I went to a small, private Presbyterian (I think) college, and there were a lot of upper-middle cl students who had gone to private high schools and prep schools. It was kind of similar to a small, private Episcopalian college I almost went to before it, although with a more reformed aspect in some groups than the Episcopalian one, it seemed. Anyway, I went on medical leave, and I'm thinking about going to a small, private Catholic college now, and I wondered what differences there might be. The Catholic college is in New England, and I was born and raised in the South. I don't really have a Southern mentality, though.
