I loved going to MC. The community felt more like a family than a school, people really cared about one another. Teachers are committed at this school, you could tell they actually care about the student's academic success and general well being. The religious aspect of the school was really special too, offering a moral backbone to an age that really needs some morality! I would highly recommend this school to people who truly care about investing in their education and their future!
