Can you narrow the universe down a little bit for us? What part of the country, how big or small a school, any idea what you might want to study and any cultural preferences? For example is it important for you to attend a Catholic college (based on your Catholic HS), not important but you might prefer a more conservative school, or not important at all and you could be happy at a very liberal/activist school?
I think those big questions will help the group point you in the right starting direction. Best of luck.
