I don't know of any non-Catholics gaining a place there for this year. They are now an Academy and can set their own entrance criteria. There is a list of criteria published somewhere on this site (I don't know where or I'd copy it). It goes from 1 to 8 think. For example, you would fit into Category 1 if you had a sister at the school and were Catholic. Category 8 was girls of no religion. Don't quote me on this, it's just an example, but we fit into the last category. This subject sticks in my throat.
Someone else will come along and offer more help.
