Considering going to a Christian school, but I’m not Christian

I’m thinking about taking classes for my masters in clinical mental health at a Christian university but I’m not Christian. The classes seem really interesting and the study abroad opportunity really sealed it for me. But since I’m not Christian, I’m not sure what will be expected of me. I’m more agnostic. I asked my cousin if she could be the reference but I feel like a fraud lying like that. Any opinions ? Lol Edit: it’s Houston Christian University and its the Masters in Clincal Mental Health
