Are you a senior? If so apply anyway…assuming you can pay for the application feel and SAT scores to be sent. See what happens…and then start talking to them.
If you are junior, figure out what attributes of the college there are. Small? Urban? Has such adn such major? Most likely there are other schools similar. You can look for “overlap” colleges…ones that are similar.
Either way, you would have to convince your parents that this college would be okay.
If you are protestant/jewish but you are looking at a catholic school, you might talk to them about the clubs that match your religion and how day to day classes are not influenced by the religion.
BUt if you were Jewish and wanted to go to a fundamentalist Christian or Mormon school, they may have stronger concerns.
