I disagree @coolguy40 . The first step is to read online whether they have any sort of "moral contract" that requires things like "no premarital sex" "no drinking even if you're 21 on or off campus" "homosexuality not allowed", and perhaps whether or not it has chapel requirements. If it has any of those, it's an incredibly religious school, and probably not worth touring if you don't subscribe that sort of religious beliefs.
Can you see if you can take the course at a local community college? If the college advertises their finance degree and then barely offers the core courses required to graduate on time, it seems like the school could plan better.
If it's a teacher I'm trying to impress I tend to dress a little nicer. For example, for Intro to Finance I try to dress a little nicer. However, for critical reasoning I'll dress more casual because I care less.
