Why are you interested in considering Catholic colleges if “too Catholic” is a concern? There are lots of other good choices. Not trying to be challenging to you; it just would be helpful to know to answer the question.
It might be helpful if you define “too Catholic”. I know several former BC and PC students, but I don’t really know what to respond to.
If the school is otherwise a good fit for you, I wouldn’t worry about it. Just as I wouldn’t worry about Brandeis being “too Jewish”. A great educational opportunity is a great opportunity regardless.
