City Year/AmeriCorps questions

I just looked at my FastWeb scholarship site and saw an offer to do the City Year program and get about $5000 for my education. I’m within 18 months of graduating with my BA and teaching certificate, but I’m not sure if I’m ready for the post-collegiate world yet. Has anyone had any experience with City Year or AmeriCorps? I heard of both in high school, but the time wasn’t right for me back then.
