Christian life

My D is thinking of TCU. When we went to visit they said the “C” can be as big or small as you want. My D knows she wants to find a strong, diverse group of Christian friends that are very socially active. Right now she goes to 2 different Bible studies- one with older more mature Christians like herself and one that is more for new Christians (she feels she can bring kids from school there). My S went to a large school but when he tried to get involved in some Christian activities he discovered that they seemed to be rather closed (Athletes for Action was like the NAACP, and Bible Study on campus was like a Korean Church and no one spoke with him). Can anyone tell me about some of the Christian groups on campus or about the Christian sorority? Also she is from out of state not Texas - is that a disadvantage?
