I went to a Catholic boarding school called St Edwards college for boys in a tiny island called Malta.  I'm not Catholic.  I was a "heathen" and wasn't allowed to do pretty much anything.  I went there because the school needed the money and allowed non Catholics.  I could fill volumes listing my experiences there.  I will say the education was far better than in the USA.  We were doing work that I did not experience again until the 12th grade back in the US, especially in English composition. Also I did not have to attend mass, especially morning mass.  The Catholic kids sure didn't like attending mass either...ha.  When the Headmaster came around in the morning to bless us and spray holy water from his salt shaker, us non Cathoilcs would duck from it, and if some hit us we would say "It burns, it burns"  That really angered them...
